WORKS OF ART IN DANISH PEAT.

When treating in the "Principles of Geology" of the changes of the earth

which have taken place in comparatively modern times, I have spoken of

the embedding of organic bodies and human remains in peat, and explained

under what conditions the growth of that vegetable substance is going on

in northern and humid climates. Of late years, since I first alluded

to the subject, more extensive investigations have been made into the

history of the Danish peat-mosses. Of the results of these inquiries

I shall give a brief abstract in the present chapter, that we may

afterwards compare them with deposits of older date, which throw light

on the antiquity of the human race.

The deposits of peat in Denmark,* varying in depth from 10 to 30 feet,

have been formed in hollows or depressions in the northern drift or

boulder formation hereafter to be described. (* An excellent account of

these researches of Danish naturalists and antiquaries has been drawn

up by an able Swiss geologist, M.A. Morlot, and will be found in the

"Bulletin de la Societe Vaudoise des Sci. Nat." tome 6 Lausanne 1860.)

The lowest stratum, 2 to 3 feet thick, consists of swamp-peat composed

chiefly of moss or sphagnum, above which lies another growth of peat,

not made up exclusively of aquatic or swamp plants. Around the borders

of the bogs, and at various depths in them, lie trunks of trees,

especially of the Scotch fir (Pinus sylvestris), often 3 feet in

diameter, which must have grown on the margin of the peat-mosses, and

have frequently fallen into them. This tree is not now, nor has ever

been in historical times, a native of the Danish Islands, and when

introduced there has not thriven; yet it was evidently indigenous in the

human period, for Steenstrup has taken out with his own hands a flint

instrument from below a buried trunk of one of these pines. It appears

clear that the same Scotch fir was afterwards supplanted by the sessile

variety of the common oak, of which many prostrate trunks occur in the

peat at higher levels than the pines; and still higher the pedunculated

variety of the same oak (Quercus robur, L.) occurs with the alder, birch

(Betula verrucosa, Ehrh.), and hazel. The oak has now in its turn been

almost superseded in Denmark by the common beech. Other trees, such as

the white birch (Betula alba), characterise the lower part of the

bogs, and disappear from the higher; while others again, like the aspen

(Populus tremula), occur at all levels, and still flourish in Denmark.

All the land and freshwater shells, and all the mammalia as well as the

plants, whose remains occur buried in the Danish peat, are of Recent

species. [3]

It has been stated, that a stone implement was found under a buried

Scotch fir at a great depth in the peat. By collecting and studying a

vast variety of such implements, and other articles of human workmanship

preserved in peat and in sand-dunes on the coast, as also in certain

shell-mounds of the aborigines presently to be described, the Danish

and Swedish antiquaries and naturalists, MM. Nilsson, Steenstrup,

Forchhammer, Thomsen, Worsaae, and others, have succeeded in

establishing a chronological succession of periods, which they have

called the ages of stone, of bronze, and of iron, named from the

materials which have each in their turn served for the fabrication of

implements.

The age of stone in Denmark coincided with the period of the first

vegetation, or that of the Scotch fir, and in part at least with the

second vegetation, or that of the oak. But a considerable portion of the

oak epoch coincided with "the age of bronze," for swords and shields of

that metal, now in the Museum of Copenhagen, have been taken out of peat

in which oaks abound. The age of iron corresponded more nearly with that

of the beech tree.*

(* Morlot "Bulletin de la Societe Vaudoise des Sci. Nat."

tome 6 page 292.) [4]

M. Morlot, to whom we are indebted for a masterly sketch of the recent

progress of this new line of research, followed up with so much success

in Scandinavia and Switzerland, observes that the introduction of the

first tools made of bronze among a people previously ignorant of the use

of metals, implies a great advance in the arts, for bronze is an alloy

of about nine parts of copper and one of tin; and although the former

metal, copper, is by no means rare, and is occasionally found pure or

in a native state, tin is not only scarce but never occurs native. To

detect the existence of this metal in its ore, then to disengage it

from the matrix, and finally, after blending it in due proportion with

copper, to cast the fused mixture in a mould, allowing time for it to

acquire hardness by slow cooling, all this bespeaks no small sagacity

and skilful manipulation. Accordingly, the pottery found associated with

weapons of bronze is of a more ornamental and tasteful style than any

which belongs to the age of stone. Some of the moulds in which the

bronze instruments were cast, and "tags," as they are called, of bronze,

which are formed in the hole through which the fused metal was poured,

have been found. The number and variety of objects belonging to the age

of bronze indicates its long duration, as does the progress in the arts

implied by the rudeness of the earlier tools, often mere repetitions

of those of the stone age, as contrasted with the more skilfully worked

weapons of a later stage of the same period.

It has been suggested that an age of copper must always have intervened

between that of stone and bronze; but if so, the interval seems to have

been short in Europe, owing apparently to the territory occupied by the

aboriginal inhabitants having been invaded and conquered by a people

coming from the East, to whom the use of swords, spears, and other

weapons of bronze was familiar. Hatchets, however, of copper have been

found in the Danish peat.

The next stage of improvement, or that manifested by the substitution of

iron for bronze, indicates another stride in the progress of the arts.

Iron never presents itself, except in meteorites, in a native state,

so that to recognise its ores, and then to separate the metal from its

matrix, demands no inconsiderable exercise of the powers of observation

and invention. To fuse the ore requires an intense heat, not to be

obtained without artificial appliances, such as pipes inflated by the

human breath, or bellows, or some other suitable machinery.

DANISH SHELL-MOUNDS, OR KJOKKENMODDING.*

(* Mr. John Lubbock published, after these sheets were

written, an able paper on the Danish "Shell-mounds" in the

October number of the "Natural History Review" 1861 page

489, in which he has described the results of a recent visit

to Denmark, made by him in company with Mr. Busk.)

In addition to the peat-mosses, another class of memorials found in

Denmark has thrown light on the pre-historical age. At certain points

along the shores of nearly all the Danish islands, mounds may be seen,

consisting chiefly of thousands of cast-away shells of the oyster,

cockle, and other molluscs of the same species as those which are now

eaten by Man. These shells are plentifully mixed up with the bones of

various quadrupeds, birds, and fish, which served as the food of the

rude hunters and fishers by whom the mounds were accumulated. I have

seen similar large heaps of oysters, and other marine shells with

interspersed stone implements, near the seashore, both in Massachusetts

and in Georgia, U.S.A., left by the native North American Indians at

points near to which they were in the habit of pitching their wigwams

for centuries before the white man arrived.

Such accumulations are called by the Danes, Kjokkenmodding, or

"kitchen-middens." Scattered all through them are flint knives,

hatchets, and other instruments of stone, horn, wood, and bone, with

fragments of coarse pottery, mixed with charcoal and cinders, but never

any implements of bronze, still less of iron. The stone hatchets and

knives had been sharpened by rubbing, and in this respect are one degree

less rude than those of an older date, associated in France with the

bones of extinct mammalia, of which more in the sequel. The mounds vary

in height from 3 to 10 feet, and in area are some of them 1000 feet

long, and from 150 to 200 wide. They are rarely placed more than 10

feet above the level of the sea, and are confined to its immediate

neighbourhood, or if not (and there are cases where they are several

miles from the shore), the distance is ascribable to the entrance of a

small stream, which has deposited sediment, or to the growth of a peaty

swamp, by which the land has been made to advance on the Baltic, as it

is still doing in many places, aided, according to Puggaard, by a very

slow upheaval of the whole country at the rate of 2 or 3 inches in a

century.

There is also another geographical fact equally in favour of the

antiquity of the mounds, namely, that they are wanting on those parts of

the coast which border the Western Ocean, or exactly where the waves are

now slowly eating away the land. There is every reason to presume that

originally there were stations along the coast of the North Sea as well

as that of the Baltic, but by the gradual undermining of the cliffs they

have all been swept away.

Another striking proof, perhaps the most conclusive of all, that the

"kitchen-middens" are very old, is derived from the character of their

embedded shells. These consist entirely of living species; but, in the

first place, the common eatable oyster is among them, attaining its

full size, whereas the same Ostrea edulis cannot live at present in the

brackish waters of the Baltic except near its entrance, where, whenever

a north-westerly gale prevails, a current setting in from the ocean

pours in a great body of salt water. Yet it seems that during the whole

time of the accumulation of the "kitchen-middens" the oyster flourished

in places from which it is now excluded. In like manner the eatable

cockle, mussel, and periwinkle (Cardium edule, Mytilus edulis, and

Littorina littorea), which are met with in great numbers in the

"middens," are of the ordinary dimensions which they acquire in the

ocean, whereas the same species now living in the adjoining parts of

the Baltic only attain a third of their natural size, being stunted and

dwarfed in their growth by the quantity of fresh water poured by rivers

into that inland sea.*

(* See "Principles of Geology" chapter 30.)

Hence we may confidently infer that in the days of the aboriginal

hunters and fishers, the ocean had freer access than now to the Baltic,

communicating probably through the peninsula of Jutland, Jutland having

been at no remote period an archipelago. Even in the course of the

nineteenth century, the salt waters have made one irruption into the

Baltic by the Lymfiord, although they have been now again excluded. It

is also affirmed that other channels were open in historical times which

are now silted up.*

(* See Morlot "Bulletin de la Societe Vaudoise des Sci.

Nat." tome 6.)

If we next turn to the remains of vertebrata preserved in the mounds,

we find that here also, as in the Danish peat-mosses, all the quadrupeds

belong to species known to have inhabited Europe within the memory of

Man. No remains of the mammoth, or rhinoceros, or of any extinct

species appear, except those of the wild bull (Bos urus, Linn., or Bos

primigenius, Bojanus), which are in such numbers as to prove that the

species was a favourite food of the ancient people. But as this animal

was seen by Julius Caesar, and survived long after his time, its

presence alone would not go far to prove the mounds to be of high

antiquity. The Lithuanian aurochs or bison (Bos bison, L., Bos priscus,

Boj.), which has escaped extirpation only because protected by the

Russian Czars, surviving in one forest in Lithuania) has not yet been

met with, but will no doubt be detected hereafter, as it has been

already found in the Danish peat. The beaver, long since destroyed in

Denmark, occurs frequently, as does the seal (Phoca Gryppus, Fab.), now

very rare on the Danish coast. With these are mingled bones of the red

deer and roe, but the reindeer has not yet been found. There are also

the bones of many carnivora, such as the lynx, fox, and wolf, but no

signs of any domesticated animals except the dog. The long bones of the

larger mammalia have been all broken as if by some instrument, in such

a manner as to allow of the extraction of the marrow, and the gristly

parts have been gnawed off, as if by dogs, to whose agency is also

attributed the almost entire absence of the bones of young birds and of

the smaller bones and softer parts of the skeletons of birds in general,

even of those of large size. In reference to the latter, it has been

proved experimentally by Professor Steenstrup, that if the same species

of birds are now given to dogs, they will devour those parts of the

skeleton which are missing, and leave just those which are preserved in

the old "kitchen-middens."

The dogs of the mounds, the only domesticated animals, are of a smaller

race than those of the bronze period, as shown by the peat-mosses, and

the dogs of the bronze age are inferior in size and strength to those

of the iron age. The domestic ox, horse, and sheep, which are wanting

in the mounds, are confined to that part of the Danish peat which was

formed in the ages of bronze and iron.

Among the bones of birds, scarcely any are more frequent in the mounds

than those of the auk (Alca impennis), now extinct. The Capercailzie

(Tetrao urogallus) is also met with, and may, it is suggested, have fed

on the buds of the Scotch fir in times when that tree flourished around

the peat-bogs. The different stages of growth of the roedeer's horns,

and the presence of the wild swan, now only a winter visitor, have

been appealed to as proving that the aborigines resided in the same

settlements all the year round. That they also ventured out to sea in

canoes such as are now found in the peat-mosses, hollowed out of the

trunk of a single tree, to catch fish far from land, is testified by the

bony relics of several deep-sea species, such as the herring, cod, and

flounder. The ancient people were not cannibals, for no human bones

are mingled with the spoils of the chase. Skulls, however, have been

obtained not only from peat, but from tumuli of the stone period

believed to be contemporaneous with the mounds. These skulls are small

and round, and have a prominent ridge over the orbits of the eyes,

showing that the ancient race was of small stature, with round heads and

overhanging eyebrows--in short, they bore a considerable resemblance to

the modern Laplanders. The human skulls of the bronze age found in the

Danish peat, and those of the iron period, are of an elongated form and

larger size. There appear to be very few well-authenticated examples

of crania referable to the bronze period--a circumstance no doubt

attributable to the custom prevalent among the people of that era of

burning their dead and collecting their bones in funeral urns.

No traces of grain of any sort have hitherto been discovered, nor

any other indication that the ancient people had any knowledge of

agriculture. The only vegetable remains in the mounds are burnt pieces

of wood and some charred substance referred by Dr. Forchhammer to the

Zostera marina, a sea plant which was perhaps used in the production of

salt.

What may be the antiquity of the earliest human remains preserved in

the Danish peat cannot be estimated in centuries with any approach

to accuracy. In the first place, in going back to the bronze age, we

already find ourselves beyond the reach of history or even of tradition.

In the time of the Romans the Danish Isles were covered, as now, with

magnificent beech forests. Nowhere in the world does this tree flourish

more luxuriantly than in Denmark, and eighteen centuries seem to have

done little or nothing towards modifying the character of the forest

vegetation. Yet in the antecedent bronze period there were no beech

trees, or at most but a few stragglers, the country being then covered

with oak. In the age of stone again, the Scotch fir prevailed, and

already there were human inhabitants in those old pine forests. How many

generations of each species of tree flourished in succession before the

pine was supplanted by the oak, and the oak by the beech, can be but

vaguely conjectured, but the minimum of time required for the formation

of so much peat must, according to the estimate of Steenstrup and other

good authorities, have amounted to at least 4000 years; and there

is nothing in the observed rate of the growth of peat opposed to the

conclusion that the number of centuries may not have been four times as

great, even though the signs of Man's existence have not yet been traced

down to the lowest or amorphous stratum. As to the "kitchen-middens,"

they correspond in date to the older portion of the peaty record, or to

the earliest part of the age of stone as known in Denmark.

ANCIENT SWISS LAKE-DWELLINGS, BUILT ON PILES.

[Illustration: Plate 1. Swiss Lake-Dwellings]

In the shallow parts of many Swiss lakes, where there is a depth of no

more than from 5 to 15 feet of water, ancient wooden piles are observed

at the bottom sometimes worn down to the surface of the mud, sometimes

projecting slightly above it. These have evidently once supported

villages, nearly all of them of unknown date, but the most ancient of

which certainly belonged to the age of stone, for hundreds of implements

resembling those of the Danish shell-mounds and peat-mosses have been

dredged up from the mud into which the piles were driven.

The earliest historical account of such habitations is that given by

Herodotus of a Thracian tribe, who dwelt, in the year 520 B.C., in

Prasias, a small mountain-lake of Paeonia, now part of modern Roumelia.*

(* Herodotus lib. 5 cap. 16. Rediscovered by M. de Ville

"Natural History Review" volume 2 1862 page 486.)

Their habitations were constructed on platforms raised above the lake,

and resting on piles. They were connected with the shore by a narrow

causeway of similar formation. Such platforms must have been of

considerable extent, for the Paeonians lived there with their families

and horses. Their food consisted largely of the fish which the lake

produced in abundance.

In rude and unsettled times, such insular sites afforded safe retreats,

all communication with the mainland being cut off, except by boats, or

by such wooden bridges as could be easily removed.

The Swiss lake-dwellings seem first to have attracted attention during

the dry winter of 1853-54, when the lakes and rivers sank lower than had

ever been previously known, and when the inhabitants of Meilen, on the

Lake of Zurich, resolved to raise the level of some ground and turn it

into land, by throwing mud upon it obtained by dredging in the adjoining

shallow water. During these dredging operations they discovered a number

of wooden piles deeply driven into the bed of the lake, and among them

a great many hammers, axes, celts, and other instruments. All these

belonged to the stone period with two exceptions, namely, an armlet of

thin brass wire, and a small bronze hatchet.

Fragments of rude pottery fashioned by the hand were abundant, also

masses of charred wood, supposed to have formed parts of the platform

on which the wooden cabins were built. Of this burnt timber, on this and

other sites, subsequently explored, there was such an abundance as to

lead to the conclusion that many of the settlements must have perished

by fire. Herodotus has recorded that the Paeonians, above alluded to,

preserved their independence during the Persian invasion, and defied the

attacks of Darius by aid of the peculiar position of their dwellings.

"But their safety," observes Mr. Wylie,* "was probably owing to their

living in the middle of the lake, (Greek) en mese te limne, whereas the

ancient Swiss settlers were compelled by the rapidly increasing depth of

the water near the margins of their lakes to construct their habitations

at a short distance from the shore, within easy bowshot of the land, and

therefore not out of reach of fiery projectiles, against which thatched

roofs and wooden walls could present but a poor defence."

(* W.M. Wylie "Archaeologia" volume 38 1859, a valuable

paper on the Swiss and Irish lake-habitations.)

To these circumstances and to accidental fires we are probably indebted

for the frequent preservation, in the mud around the site of the old

settlements, of the most precious tools and works of art, such as would

never have been thrown into the Danish "kitchen-middens," which have

been aptly compared to a modern dusthole.

Dr. Ferdinand Keller of Zurich has drawn up a series of most instructive

memoirs, illustrated with well-executed plates, of the treasures

in stone, bronze, and bone brought to light in these subaqueous

repositories, and has given an ideal restoration of part of one of the

old villages (see Plate 1 above),* such as he conceives may have existed

on the lakes of Zurich and Bienne.

(*Keller "Pfahlbauten, Antiquarische Gesellschaft in Zurich"

Bd. 12 and 13 1858-1861. In the fifth number of the "Natural

History Review" January 9, 1862, Mr. Lubbock has published

an excellent account of the works of the Swiss writers on

their lake-habitations.)

In this view, however, he has not simply trusted to his imagination,

but has availed himself of a sketch published by M. Dumont d'Urville, of

similar habitations of the Papuans in New Guinea in the Bay of Dorei. It

is also stated by Dr. Keller, that on the River Limmat, near Zurich, so

late as the last century, there were several fishing-huts constructed on

this same plan.*

(* Keller "Pfahlbauten, Antiquarische Gesellschaft in

Zurich" Bd. 9 page 81 note.)

It will be remarked that one of the cabins is represented as circular.

That such was the form of many in Switzerland is inferred from the

shape of pieces of clay which lined the interior, and which owe their

preservation apparently to their having been hardened by fire when the

village was burnt. In the sketch (Plate 1), some fishing-nets are seen

spread out to dry on the wooden platform. The Swiss archaeologist has

found abundant evidence of fishing-gear, consisting of pieces of cord,

hooks, and stones used as weights. A canoe also is introduced, such as

are occasionally met with. One of these, made of the trunk of a single

tree, fifty feet long and three and a half feet wide, was found capsized

at the bottom of the Lake of Bienne. It appears to have been laden

with stones, such as were used to raise the foundation of some of the

artificial islands.

It is believed that as many as 300 wooden huts were sometimes comprised

in one settlement, and that they may have contained about 1000

inhabitants. At Wangen, M. Lohle has calculated that 40,000 piles were

used, probably not all planted at one time nor by one generation. Among

the works of great merit devoted specially to a description of the Swiss

lake-habitations is that of M. Troyon, published in 1860.*

(* "Sur les Habitations lacustres.")

The number of sites which he and other authors have already enumerated

in Switzerland is truly wonderful. They occur on the large lakes of

Constance, Zurich, Geneva, and Neufchatel, and on most of the smaller

ones. Some are exclusively of the stone age, others of the bronze

period. Of these last more than twenty are spoken of on the Lake of

Geneva alone, more than forty on that of Neufchatel, and twenty on the

small Lake of Bienne.

One of the sites first studied by the Swiss antiquaries was the small

lake of Moosseedorf, near Berne, where implements of stone, horn, and

bone, but none of metal, were obtained. Although the flint here employed

must have come from a distance (probably from the south of France), the

chippings of the material are in such profusion as to imply that there

was a manufactory of implements on the spot. Here also, as in several

other settlements, hatchets and wedges of jade have been observed of a

kind said not to occur in Switzerland or the adjoining parts of Europe,

and which some mineralogists would fain derive from the East; amber

also, which, it is supposed, was imported from the shores of the Baltic.

At Wangen near Stein, on the Lake of Constance, another of the most

ancient of the lake-dwellings, hatchets of serpentine and greenstone,

and arrow-heads of quartz have been met with. Here also remains of a

kind of cloth, supposed to be of flax, not woven but plaited, have

been detected. Professor Heer has recognised lumps of carbonised wheat,

Triticum vulgare, and grains of another kind, T. dicoccum, and barley,

Hordeum distichum, and flat round cakes of bread; and at Robbenhausen

and elsewhere Hordeum hexastichum in fine ears, the same kind of barley

which is found associated with Egyptian mummies, showing clearly that in

the stone period the lake-dwellers cultivated all these cereals, besides

having domesticated the dog, the ox, the sheep, and the goat.

Carbonised apples and pears of small size, such as still grow in the

Swiss forests, stones of the wild plum, seeds of the raspberry and

blackberry, and beech-nuts, also occur in the mud, and hazel-nuts in

great plenty.

Near Morges, on the Lake of Geneva, a settlement of the bronze period,

no less than forty hatchets of that metal have been dredged up, and in

many other localities the number and variety of weapons and utensils

discovered, in a fine state of preservation, is truly astonishing.

It is remarkable that as yet all the settlements of the bronze period

are confined to Western and Central Switzerland. In the more eastern

lakes those of the stone period alone have as yet been discovered.

The tools, ornaments, and pottery of the bronze period in Switzerland

bear a close resemblance to those of corresponding age in Denmark,

attesting the wide spread of a uniform civilisation over Central Europe

at that era. In some few of the Swiss aquatic stations a mixture of

bronze and iron implements has been observed, but no coins. At Tiefenau,

near Berne, in ground supposed to have been a battle-field, coins

and medals of bronze and silver, struck at Marseilles, and of Greek

manufacture, and iron swords, have been found, all belonging to the

first and pre-Roman division of the age of iron.

In the settlements of the bronze era the wooden piles are not so much

decayed as those of the stone period; the latter having wasted down

quite to the level of the mud, whereas the piles of the bronze age (as

in the Lake of Bienne, for example) still project above it.

Professor Rutimeyer of Basle, well-known to palaeontologists as the

author of several important memoirs on fossil vertebrata, has recently

published a scientific description of great interest of the animal

remains dredged up at various stations where they had been embedded for

ages in the mud into which the piles were driven.*

(* "Die Fauna der Pfahlbauten in der Schweiz" Basel 1861.)

These bones bear the same relation to the primitive inhabitants of

Switzerland and some of their immediate successors as do the contents of

the Danish "kitchen-middens" to the ancient fishing and hunting tribes

who lived on the shores of the Baltic.

The list of wild mammalia enumerated in this excellent treatise contains

no less than twenty-four species, exclusive of several domesticated

ones: besides which there are eighteen species of birds, the wild swan,

goose, and two species of ducks being among them; also three reptiles,

including the eatable frog and freshwater tortoise; and lastly, nine

species of freshwater fish. All these (amounting to fifty-four species)

are with one exception still living in Europe. The exception is the wild

bull (Bos primigenius), which, as before stated, survived in historical

times. The following are the mammalia alluded to:--The bear (Ursus

arctos), the badger, the common marten, the polecat, the ermine, the

weasel, the otter, wolf, fox, wild cat, hedgehog, squirrel, field-mouse

(Mus sylvaticus), hare, beaver, hog (comprising two races, namely, the

wild boar and swamp-hog), the stag (Cervus elaphus), the roe-deer,

the fallow-deer, the elk, the steinbock (Capra ibex), the chamois, the

Lithuanian bison, and the wild bull. The domesticated species comprise

the dog, horse, ass, pig, goat, sheep, and several bovine races.

The greater number, if not all, of these animals served for food, and

all the bones which contained marrow have been split open in the same

way as the corresponding ones found in the shell-mounds of Denmark

before mentioned. The bones both of the wild bull and the bison are

invariably split in this manner. As a rule, the lower jaws with teeth

occur in greater abundance than any other parts of the skeleton--a

circumstance which, geologists know, holds good in regard to fossil

mammalia of all periods. As yet the reindeer is missing in the Swiss

lake-settlements as in the Danish "kitchen-middens," although this

animal in more ancient times ranged over France, together with the

mammoth, as far south as the Pyrenees.

A careful comparison of the bones from different sites has shown that

in settlements such as Wangen and Moosseedorf, belonging to the earliest

age of stone, when the habits of the hunter state predominated over

those of the pastoral, venison, or the flesh of the stag and roe, was

more eaten than the flesh of the domestic cattle and sheep. This was

afterwards reversed in the later stone period and in the age of bronze.

At that later period also the tame pig, which is wanting in some of the

oldest stations, had replaced the wild boar as a common article of

food. In the beginning of the age of stone, in Switzerland, the goats

outnumbered the sheep, but towards the close of the same period the

sheep were more abundant than the goats.

The fox in the first era was very common, but it nearly disappears in

the bronze age, during which period a large hunting-dog, supposed to

have been imported into Switzerland from some foreign country, becomes

the chief representative of the canine genus.

A single fragment of the bone of a hare (Lepus timidus) has been found

at Moosseedorf. The almost universal absence of this quadruped is

supposed to imply that the Swiss lake-dwellers were prevented from

eating that animal by the same superstition which now prevails among

the Laplanders, and which Julius Caesar found in full force amongst the

ancient Britons.*

(* "Commentaries" lib 5 chapter 12.)

That the lake-dwellers should have fed so largely on the fox, while

they abstained from touching the hare, establishes, says Rutimeyer, a

singular contrast between their tastes and ours.

Even in the earliest settlements, as already hinted, several

domesticated animals occur, namely, the ox, sheep, goat, and dog. Of the

three last, each was represented by one race only; but there were two

races of cattle, the most common being of small size, and called by

Rutimeyer Bos brachyceros (Bos longifrons, Owen), or the marsh cow,

the other derived from the wild bull; though, as no skull has yet been

discovered, this identification is not so certain as could be wished.

It is, however, beyond question that at a later era, namely, towards the

close of the stone and beginning of the bronze period, the lake-dwellers

had succeeded in taming that formidable brute the Bos primigenius, the

Urus of Caesar, which he described as very fierce, swift, and strong,

and scarcely inferior to the elephant in size. In a tame state its

bones were somewhat less massive and heavy, and its horns were somewhat

smaller than in wild individuals. Still in its domesticated form, it

rivalled in dimensions the largest living cattle, those of Friesland,

in North Holland, for example. When most abundant, as at Concise on

the Lake of Neufchatel, it had nearly superseded the smaller race,

Bos brachyceros, and was accompanied there for a short time by a third

bovine variety, called Bos trochoceros, an Italian race, supposed

to have been imported from the southern side of the Alps. (Caesar

"Commentaries" lib 5 chapter 12.) This last-mentioned race, however,

seems only to have lasted for a short time in Switzerland.

The wild bull (Bos primigenius) is supposed to have flourished for a

while in a wild and tame state, just as now in Europe the domestic

pig co-exists with the wild boar; and Rutimeyer agrees with Cuvier and

Bell,* in considering our larger domestic cattle of northern Europe as

the descendants of this wild bull, an opinion which Owen disputes.**

(* "British Quadrupeds" page 415.)

(** "British Fossil Mammal." page 500.)

In the later division of the stone period, there were two tame races of

the pig, according to Rutimeyer; one large, and derived from the

wild boar, the other smaller, called the "marsh-hog," or Sus scrofa

palustris. It may be asked how the osteologist can distinguish the tame

from the wild races of the same species by their skeletons alone.

Among other characters, the diminished thickness of the bones and the

comparative smallness of the ridges, which afford attachment to the

muscles, are relied on; also the smaller dimensions of the tusks in

the boar, and of the whole jaw and skull; and, in like manner, the

diminished size of the horns of the bull and other modifications, which

are the effects of a regular supply of food, and the absence of all

necessity of exerting their activity and strength to obtain subsistence

and defend themselves against their enemies.

A middle-sized race of dogs continued unaltered throughout the whole of

the stone period; but the people of the bronze age possessed a larger

hunting-dog, and with it a small horse, of which genus very few traces

have been detected in the earlier settlements--a single tooth, for

example, at Wangen, and only one or two bones at two or three other

places.

In passing from the oldest to the most modern sites, the extirpation of

the elk and beaver, and the gradual reduction in numbers of the bear,

stag, roe, and freshwater tortoise are distinctly perceptible. The

aurochs, or Lithuanian bison, appears to have died out in Switzerland

about the time when weapons of bronze came into use. It is only in a few

of the most modern lake-dwellings, such as Noville and Chavannes in the

Canton de Vaud (which the antiquaries refer to the sixth century), that

some traces are observable of the domestic cat, as well as of a sheep

with crooked horns and with them bones of the domestic fowl.

After the sixth century, no extinction of any wild quadruped nor

introduction of any tame one appears to have taken place, but the fauna

was still modified by the wild species continuing to diminish in number

and the tame ones to become more diversified by breeding and crossing,

especially in the case of the dog, horse, and sheep. On the whole,

however, the divergence of the domestic races from their aboriginal wild

types, as exemplified at Wangen and Moosseedorf, is confined, according

to Professor Rutimeyer, within narrow limits. As to the goat, it has

remained nearly constant and true to its pristine form, and the small

race of goat-horned sheep still lingers in some alpine valleys in the

Upper Rhine; and in the same region a race of pigs, corresponding to the

domesticated variety of Sus scrofa palustris, may still be seen.

Amidst all this profusion of animal remains extremely few bones of Man

have been discovered; and only one skull, dredged up from Meilen, on

the Lake of Zurich, of the early stone period, seems as yet to have been

carefully examined. Respecting this specimen, Professor His observes

that it exhibits, instead of the small and rounded form proper to

the Danish peat-mosses, a type much more like that now prevailing

in Switzerland, which is intermediate between the long-headed and

short-headed form. (Rutimeyer "Die Fauna der Pfahlbauten in der Schweiz"

page 181.)

So far, therefore, as we can draw safe conclusions from a single

specimen, there has been no marked change of race in the human

population of Switzerland during the periods above considered.

It is still a question whether any of these subaqueous repositories

of ancient relics in Switzerland go back so far in time as the

kitchen-middens of Denmark, for in these last there are no domesticated

animals except the dog, and no signs of the cultivation of wheat or

barley; whereas we have seen that, in one of the oldest of the

Swiss settlements, at Wangen, no less than three cereals make their

appearance, with four kinds of domestic animals. Yet there is no small

risk of error in speculating on the relative claims to antiquity of such

ancient tribes, for some of them may have remained isolated for ages and

stationary in their habits, while others advanced and improved.

We know that nations, both before and after the introduction of metals,

may continue in very different stages of civilisation, even after

commercial intercourse has been established between them, and where they

are separated by a less distance than that which divides the Alps from

the Baltic.

The attempts of the Swiss geologists and archaeologists to estimate

definitely in years the antiquity of the bronze and stone periods,

although as yet confessedly imperfect, deserve notice, and appear to me

to be full of promise. The most elaborate calculation is that made by M.

Morlot, respecting the delta of the Tiniere, a torrent which flows

into the Lake of Geneva near Villeneuve. This small delta, to which the

stream is annually making additions, is composed of gravel and sand.

Its shape is that of a flattened cone, and its internal structure has of

late been laid open to view in a railway cutting 1000 feet long and 32

feet deep. The regularity of its structure throughout implies that it

has been formed very gradually, and by the uniform action of the same

causes. Three layers of vegetable soil, each of which must at one time

have formed the surface of the cone, have been cut through at different

depths. The first of these was traced over a surface of 15,000 square

feet, having an average thickness of 5 inches, and being about 4 feet

below the present surface of the cone. This upper layer belonged to the

Roman period, and contained Roman tiles and a coin. The second layer,

followed over a surface of 25,000 square feet, was 6 inches thick, and

lay at a depth of 10 feet. In it were found fragments of unvarnished

pottery and a pair of tweezers in bronze, indicating the bronze epoch.

The third layer, followed for 35,000 square feet, was 6 or 7 inches

thick and 19 feet deep. In it were fragments of rude pottery, pieces of

charcoal, broken bones, and a human skeleton having a small, round and

very thick skull. M. Morlot, assuming the Roman period to represent an

antiquity of from sixteen to eighteen centuries, assigns to the bronze

age a date of between 3000 and 4000 years, and to the oldest layer, that

of the stone period, an age of from 5000 to 7000 years.

Another calculation has been made by M. Troyon to obtain the approximate

date of the remains of an ancient settlement built on piles and

preserved in a peat-bog at Chamblon, near Yverdun, on the Lake of

Neufchatel. The site of the ancient Roman town of Eburodunum (Yverdun),

once on the borders of the lake, and between which and the shore there

now intervenes a zone of newly-gained dry land, 2500 feet in breadth,

shows the rate at which the bed of the lake has been filled up with

river sediment in fifteen centuries. Assuming the lake to have retreated

at the same rate before the Roman period, the pile-works of Chamblon,

which are of the bronze period, must be at the least 3300 years old.

For the third calculation, communicated to me by M. Morlot, we are

indebted to M. Victor Gillieron, of Neuveville, on the Lake of Bienne.

It relates to the age of a pile-dwelling, the mammalian bones of which

are considered by M. Rutimeyer to indicate the earliest portion of

the stone period of Switzerland, and to correspond in age with the

settlement of Moosseedorf.

The piles in question occur at the Pont de Thiele, between the lakes of

Bienne and Neufchatel. The old convent of St. Jean, founded 750 years

ago, and built originally on the margin of the Lake of Bienne, is now

at a considerable distance from the shore, and affords a measure of the

rate of the gain of land in seven centuries and a half. Assuming that

a similar rate of the conversion of water into marshy land prevailed

antecedently, we should require an addition of sixty centuries for the

growth of the morass intervening between the convent and the aquatic

dwelling of Pont de Thiele, in all 6750 years. M. Morlot, after

examining the ground, thinks it highly probable that the shape of the

bottom on which the morass rests is uniform; but this important point

has not yet been tested by boring. The result, if confirmed, would agree

exceedingly well with the chronological computation before mentioned

of the age of the stone period of Tiniere. As I have not myself visited

Switzerland since these chronological speculations were first hazarded,

I am unable to enter critically into a discussion of the objections

which have been raised to the two first of them, or to decide on the

merits of the explanations offered in reply.

IRISH LAKE-DWELLINGS OR CRANNOGES.

The lake-dwellings of the British isles, although not explored as yet

with scientific zeal, as those of Switzerland have been in the last ten

years, are yet known to be very numerous, and when carefully examined

will not fail to throw great light on the history of the bronze and

stone periods.

In the lakes of Ireland alone, no less than forty-six examples of

artificial islands, called crannoges, have been discovered. They occur

in Leitrim, Roscommon, Cavan, Down, Monaghan, Limerick, Meath, King's

County, and Tyrone.*

(* W.M. Wylie "Archaeologia" volume 38 1859 page 8.)

One class of these "stockaded islands," as they have been sometimes

called, was formed, according to Mr. Digby Wyatt, by placing horizontal

oak beams at the bottom of the lake, into which oak posts, from 6 to

8 feet high, were mortised, and held together by cross beams, till a

circular enclosure was obtained.

A space of 520 feet diameter, thus enclosed at Lagore, was divided into

sundry timbered compartments, which were found filled up with mud or

earth, from which were taken "vast quantities of the bones of oxen,

swine, deer, goats, sheep, dogs, foxes, horses, and asses." All these

were discovered beneath 16 feet of bog, and were used for manure; but

specimens of them are said to be preserved in the museum of the Royal

Irish Academy. From the same spot were obtained a great collection of

antiquities, which, according to Lord Talbot de Malahide and Mr. Wylie,

were referable to the ages of stone, bronze, and iron.*

(* W.M. Wylie "Archaeologia" volume 38 1859 page 8, who

cites "Archaeological Journal" volume 6 page 101.)

In Ardekillin Lake, in Roscommon, an islet of an oval form was observed,

made of a layer of stones resting on logs of timber. Round this

artificial islet or crannoge thus formed was a stone wall raised on oak

piles. A careful description has been put on record by Captain Mudge,

R.N., of a curious log-cabin discovered by him in 1833 in Drumkellin

bog, in Donegal, at a depth of 14 feet from the surface. It was 12 feet

square and 9 feet high, being divided into two stories each 4 feet high.

The planking was of oak split with wedges of stone, one of which was

found in the building. The roof was flat. A staked enclosure had been

raised round the cabin, and remains of other similar huts adjoining were

seen but not explored. A stone celt, found in the interior of the hut,

and a piece of leather sandal, also an arrow-head of flint, and in the

bog close at hand a wooden sword, give evidence of the remote antiquity

of this building, which may be taken as a type of the early dwellings on

the Crannoge islands.

"The whole structure," says Captain Mudge, "was wrought with the

rudest kind of implements, and the labour bestowed on it must have been

immense. The wood of the mortises was more bruised than cut, as if by a

blunt stone chisel."*

(* Mudge "Archaeologia" volume 26.)

Such a chisel lay on the floor of the hut, and by comparing it with

the marks of the tool used in forming the mortises, they were found "to

correspond exactly, even to the slight curved exterior of the chisel;

but the logs had been hewn by a larger instrument, in the shape of an

axe. On the floor of the dwelling lay a slab of freestone, 3 feet

long and 14 inches thick, in the centre of which was a small pit three

quarters of an inch deep, which had been chiselled out. This is presumed

to have been used for holding nuts to be cracked by means of one of the

round shingle stones, also found there, which had served as a hammer.

Some entire hazel-nuts and a great quantity of broken shells were

strewed about the floor."

The foundations of the house were made of fine sand, such as is found

with shingle on the seashore about 2 miles distant. Below the layer of

sand the bog or peat was ascertained, on probing it with an instrument,

to be at least 15 feet thick. Although the interior of the building when

discovered was full of "bog" or peaty matter, it seems when inhabited to

have been surrounded by growing trees, some of the trunks and roots

of which are still preserved in their natural position. The depth of

overlying peat affords no safe criterion for calculating the age of the

cabin or village, for I have shown in the "Principles of Geology" that

both in England and Ireland, within historical times, bogs have burst

and sent forth great volumes of black mud, which has been known to

creep over the country at a slow pace, flowing somewhat at the rate of

ordinary lava-currents, and sometimes overwhelming woods and cottages,

and leaving a deposit upon them of bog-earth 15 feet thick.

None of these Irish lake-dwellings were built, like those of Helvetia,

on platforms supported by piles deeply driven into the mud. "The

Crannoge system of Ireland seems," says Mr. Wylie, "well nigh without a

parallel in Swiss waters."
