Above weights of food are net in avoirdupois ounces. Each complete

ration with its tin container weighed nearly twenty-seven pounds. The

five pounds over net weight of daily ration was taken up in tin

necessary for protection of food. The weight of component parts of

daily ration had to be governed to some extent by the size of the

commercial package in which the food could be purchased on short

notice. Austin, Nichols & Co., of New York, who supplied the food

stores for my polar expedition, worked day and night to complete the

packing of the rations on time.

The food cases described above were used on Colonel Roosevelt's

descent of the Rio da Duvida and also by the party who journeyed down

the Gy-Parana and Madeira Rivers. Leo Miller, the naturalist, who was

a member of the last-named party, arrived in Manaos, Brazil, while I

was there and, in answer to my question, told me that the food served

admirably and was good, but that the native cooks had a habit of

opening a number of cases at a time to satisfy their personal desire

for special delicacies. Bacon was the article most sought for.

Speaking critically, for a strenuous piece of work like the

exploration of the Duvida, the food was somewhat bulky. A ration

arrangement such as I used on my sledge trips North would have

contained more nutritious elements in a smaller space. We could have

done without many of the luxuries. But the exploration of the Duvida

had not been contemplated and had no place in the itinerary mapped out

in New York. The change of plan and the decision to explore the Duvida

River came about in Rio Janeiro, long after our rations had been made

out and shipped.

"Matte" the tea of Brazil and Paraguay, used in most of the states of

South America, should not be forgotten. It is a valuable beverage.

With it a native can do a wonderful amount of work on little food.

Upon the tired traveller it has a very refreshing effect.

Doctor Peckolt, celebrated chemist of Rio de Janeiro, has compared the

analysis of matte with those of green tea, black tea, and coffee and

obtained the following result:

Manner of preparation: The matte tea is prepared in the same manner as

the Indian tea, that is to say, by pouring upon it boiling water

during ten to fifteen minutes before using. To obtain a good infusion

five spoonfuls of matte are sufficient for a litre of water.

Some experiments have been made lately with the use of matte in the

German army, and probably it would be a valuable beverage for the use

of our own troops. Two plates and a cup, knife, fork, and spoon should

be provided for each member of the party. The United States Army mess-

kit would serve admirably. Each man's mess-kit should be numbered to

correspond with the number on his duffel-bag.

An aluminum (for lightness) cooking outfit, or the Dutch oven

mentioned, with three or four kettles nested within, a coffee pot or a

teapot would suffice. The necessary large spoons and forks for the

cook, a small meat grinder, and a half dozen skinning knives could all

be included in the fibre case. These outfits are usually sold with the

cups, plates, etc., for the table. As before suggested, each member of

the party should have his own mess-kit. It should not be carried with

the general cooking outfit. By separating the eating equipments thus,

one of the problems of hygiene and cleanliness is simplified.

RIFLES--AMMUNITION--A heavy rifle is not advised. The only animals

that can be classed as dangerous are the jaguar and white-jawed

peccary, and a 30-30 or 44 calibre is heavy enough for such game. The

44-calibre Winchester or Remington carbine is the arm generally used

throughout South America, and 44 calibre is the only ammunition that

one can depend upon securing in the field. Every man has his own

preference for an arm. However, there is no need of carrying a nine or

ten pound weapon when a rifle weighing only from six and three fourths

to seven and one half pounds will do all that is necessary. I,

personally, prefer the small-calibre rifle, as it can be used for

birds also. The three-barrelled gun, combining a double shotgun and a

rifle, is an excellent weapon, and it is particularly valuable for the

collector of natural-history specimens. A new gun has just come on the

market which may prove valuable in South America where there is such a

variety of game, a four-barrel gun, weighing only eight and one fourth

pounds. It has two shotgun barrels, one 30 to 44 calibre rifle and the

rib separating the shotgun barrels is bored for a 22-calibre rifle

cartridge. The latter is particularly adapted for the large food

birds, which a heavy rifle bullet might tear. Twenty-two calibre

ammunition is also very light and the long 22 calibre exceedingly

powerful. Unless in practice it proves too complicated, it would seem

to be a good arm for all-round use--sixteen to twenty gauge is large

enough for the shotgun barrels. Too much emphasis cannot be placed

upon the need of being provided with good weapons. After the loss of

all our arms in the rapids we secured four poor, rusty rifles which

proved of no value. We lost three deer, a tapir, and other game, and

finally gave up the use of the rifles, depending upon hook and line. A

25 or 30 calibre high power automatic pistol with six or seven inch

barrel would prove a valuable arm to carry always on the person. It

could be used for large game and yet would not be too large for food

birds. It is to be regretted that there is nothing in the market of

this character.

We had our rifle ammunition packed by the U. M. C. Co. in zinc cases

of one hundred rounds each, a metallic strip with pull ring closing

the two halves of the box. Shot-cartridge, sixteen gauge, were packed

the same way, twenty-five to the box.

The explorer would do well always to have on his person a compass, a

light waterproof bag containing matches, a waterproof box of salt, and

a strong, light, linen or silk fish-line with several hooks, a knife,

and an automatic at his belt, with several loaded magazines for the

latter in his pocket. Thus provided, if accidentally lost for several

days in the forest (which often happens to the rubber hunters in

Brazil), he will be provided with the possibility of getting game and

making himself shelter and fire at night.

FISH--For small fish like the pacu and piranha an ordinary bass hook

will do. For the latter, because of its sharp teeth, a hook with a

long shank and phosphor-bronze leader is the best; the same character

of leader is best on the hook to be used for the big fish. A tarpon

hook will hold most of the great fish of the rivers. A light rod and

reel would be a convenience in catching the pacu. We used to fish for

the latter variety in the quiet pools while allowing the canoe to

drift, and always saved some of the fish as bait for the big fellows.

We fished for the pacu as the native does, kneading a ball of mandioc

farina with water and placing it on the hook as bait. I should not be

surprised, though, if it were possible, with carefully chosen flies,

to catch some of the fish that every once in a while we saw rise to

the surface and drag some luckless insect under.

CLOTHING--Even the experienced traveller when going into a new field

will commit the crime of carrying too much luggage. Articles which he

thought to be camp necessities become camp nuisances which worry his

men and kill his mules. The lighter one can travel the better. In the

matter of clothing, before the actual wilderness is reached the

costume one would wear to business in New York in summer is practical

for most of South America, except, of course, the high mountain

regions, where a warm wrap is necessary. A white or natural linen suit

is a very comfortable garment. A light blue unlined serge is desirable

as a change and for wear in rainy weather.

Strange to relate, the South American seems to have a fondness for

stiff collars. Even in Corumba, the hottest place I have ever been in,

the native does not think he is dressed unless he wears one of these

stiff abominations around his throat. A light negligee shirt with

interchangeable or attached soft collars is vastly preferable. In the

frontier regions and along the rivers the pajama seems to be the

conventional garment for day as well as night wear. Several such suits

of light material should be carried--the more ornamented and

beautifully colored the greater favor will they find along the way. A

light cravenetted mackintosh is necessary for occasional cool evenings

and as a protection against the rain. It should have no cemented

rubber seams to open up in the warm, moist climate. Yachting oxfords

and a light pair of leather slippers complete the outfit for steamer

travel. For the field, two or three light woollen khaki-colored

shirts, made with two breast pockets with buttoned flaps, two pairs

of long khaki trousers, two pairs of riding breeches, a khaki coat cut

military fashion with four pockets with buttoned flaps, two suits of

pajamas, handkerchiefs, socks, etc., would be necessary. The poncho

should extend to below the knees and should be provided with a hood

large enough to cover the helmet. It should have no cemented seams;

the material recently adopted by the United States Army for ponchos

seems to be the best. For footgear the traveller needs two pairs of

stout, high hunting shoes, built on the moccasin form with soles. Hob

nails should be taken along to insert if the going is over rocky

places. It is also advisable to provide a pair of very light leather

slipper boots to reach to just under the knee for wear in camp. They

protect the legs and ankles from insect stings and bites. The

traveller who enters tropical South America should protect his head

with a wide-brimmed soft felt hat with ventilated headband, or the

best and lightest pith helmet that can be secured, one large enough to

shade the face and back of neck. There should be a ventilating space

all around the head-band; the wider the space the better. These

helmets can be secured in Rio and Buenos Aires. Head-nets with face

plates of horsehair are the best protection against small insect

pests. They are generally made too small and the purchaser should be

careful to get one large enough to go over his helmet and come down to

the breast. Several pairs of loose gloves rather long in the wrist

will be needed as protection against the flies, piums and boroshudas

which draw blood with every bite and are numerous in many parts of

South America. A waterproof sun umbrella, with a jointed handle about

six feet long terminating in a point, would be a decided help to the

scientist at work in the field. A fine-meshed net fitting around the

edge of the umbrella would make it insect proof. When folded it would

not be bulky and its weight would be negligible. Such an umbrella

could also be attached, with a special clamp, to the thwart of a canoe

and so prove a protection from both sun and rain.

There are little personal conveniences which sometimes grow into

necessities. One of these in my own case was a little electric flash-

light taken for the purpose of reading the verniers of a theodolite or

sextant in star observations. It was used every night and for many

purposes. As a matter of necessity, where insects are numerous one

turns to the protection of his hammock and net immediately after the

evening meal. It was at such times that I found the electric lamp so

helpful. Reclining in the hammock, I held the stock of the light under

my left arm and with diary in my lap wrote up my records for the day.

I sometimes read by its soft, steady light. One charge of battery, to

my surprise, lasted nearly a month. When forced to pick out a camping

spot after dark, an experience which comes to every traveller in the

tropics in the rainy season, we found its light very helpful. Neither

rain nor wind could put it out and the light could be directed

wherever needed. The charges should be calculated on the plan of one

for every three weeks. The acetylene lamp for camp illumination is an

advance over the kerosene lantern. It has been found that for equal

weight the carbide will give more light than kerosene or candle. The

carbide should be put in small containers, for each time a box is

opened some of the contents turns into gas from contact with the moist

air.

TOOLS--Three or four good axes, several bill-hooks, a good hatchet

with hammer head and nail-puller should be in the tool kit. In

addition, each man should be provided with a belt knife and a machete

with sheath. Collins makes the best machetes. His axes, too, are

excellent. The bill-hook, called foice in Brazil, is a most valuable

tool for clearing away small trees, vines, and under-growths. It is

marvellous how quickly an experienced hand can clear the ground in a

forest with one of these instruments. All of these tools should have

handles of second-growth American hickory of first quality; and

several extra handles should be taken along. The list of tools should

be completed with a small outfit of pliers, tweezers, files, etc.--the

character, of course, depending upon the mechanical ability of the

traveller and the scientific instruments he has with him that might

need repairs.

SURVEY INSTRUMENTS--The choice of instruments will depend largely

upon the character of the work intended. If a compass survey will

suffice, there is nothing better than the cavalry sketching board used

in the United States Army for reconnaissance. With a careful hand it

approaches the high degree of perfection attained by the plane-table

method. It is particularly adapted for river survey and, after one

gets accustomed to its use, it is very simple. If the prismatic

compass is preferred, nothing smaller than two and one half inches in

diameter should be used. In the smaller sizes the magnet is not

powerful enough to move the dial quickly or accurately.

Several good pocket compasses must be provided. They should all have

good-sized needles with the north end well marked and degrees engraved

in metal. If the floating dial is preferred it should be of aluminum

and nothing smaller than two and one half inches, for the same reason

as mentioned above regarding the prismatic compass.

Expense should not be spared if it is necessary to secure good

compasses. Avoid paper dials and leather cases which absorb moisture.

The compass case should allow taking apart for cleaning and drying.

The regular chronometer movement, because of its delicacy, is out of

the question for rough land or water travel. We had with us a small-

sized half-chronometer movement recently brought out by the Waltham

Company as a yacht chronometer. It gave a surprisingly even rate under

the most adverse conditions. I was sorry to lose it in the rapids of

the Papagaio when our canoes went down.

The watches should be waterproof with strong cases, and several should

be taken. It would be well to have a dozen cheap but good watches and

the same number of compasses for use around camp and for gifts or

trade along the line of travel. Money is of no value after one leaves

the settlements. I was surprised to find that many of the rubber

hunters were not provided with compasses, and I listened to an

American who told of having been lost in the depths of the great

forest where for days he lived on monkey meat secured with his rifle

until he found his way to the river. He had no compass and could not

get one. I was sorry I had none to give; I had lost mine in the

rapids.

For the determination of latitude and longitude there is nothing

better than a small four or five inch theodolite not over fifteen

pounds in weight. It should have a good prism eyepiece with an angle

tube attached so it would not be necessary to break one's neck in

reading high altitudes. For days we travelled in the direction the sun

was going, with altitudes varying from 88° to 90°. Because of these

high altitudes of the sun the sextant with artificial horizon could

not be used unless one depended upon star observations altogether, an

uncertain dependence because of the many cloudy nights.

BAROMETERS--The Goldsmith form of direct-reading aneroid is the most

accurate portable instrument and, of course, should be compared with a

standard mercurial at the last weather-bureau station.

THERMOMETERS--A swing thermometer, with wet and dry bulbs for

determination of the amount of moisture in the air, and the maximum

and minimum thermometer of the signal-service or weather-bureau type

should be provided, with a case to protect them from injury.

A tape measure with metric scale of measurements on one side and feet

and inches on the other is most important. Two small, light waterproof

cases could be constructed and packed with scientific instruments,

data, and spare clothing and yet not exceed the weight limit of

flotation. In transit by pack-train these two cases would form but one

mule load.

PHOTOGRAPHIC--From the experience gained in several fields of

exploration it seems to me that the voyager should limit himself to

one small-sized camera, which he can always have with him, and then

carry a duplicate of it, soldered in tin, in the baggage. The

duplicate need not be equipped with as expensive a lens and shutter as

the camera carried for work; 31/4 x 41/4 is a good size. Nothing

larger than 3 1/4 x 5 1/2 is advised. We carried the 3A special Kodak

and found it a light, strong, and effective instrument. It seems to me

that the ideal form of instrument would be one with a front board

large enough to contain an adapter fitted for three lenses. For the

3 1/4 x 4 1/4:

One lens 4 or 4 1/2 focus

One lens 6 or 7 focus

One lens telephoto or telecentric 9 to 12 focus

The camera should be made of metal and fitted with focal-plane shutter

and direct view-finder.

A sole leather case with shoulder-strap should contain the camera and

lenses, with an extra roll of films, all within instant reach, so that

a lens could be changed without any loss of time.

Plates, of course, are the best, but their weight and frailty, with

difficulty of handling, rule them out of the question. The roll film

is the best, as the film pack sticks together and the stubs pull off

in the moist, hot climate. The films should be purchased in rolls of

six exposures, each roll in a tin, the cover sealed with surgical

tape. Twelve of these tubes should be soldered in a tin box. In places

where the air is charged with moisture a roll of films should not be

left in a camera over twenty-four hours.

Tank development is best for the field. The tanks provided for

developing by the Kodak Company are best for fixing also. A nest of

tanks would be a convenience; one tank should be kept separate for the

fixing-bath. As suggested in the Kodak circular, for tropical

development a large-size tank can be used for holding the freezing

mixture of hypo. This same tank would become the fixing tank after

development. In the rainy season it is a difficult matter to dry

films. Development in the field, with washing water at 80 degrees F.,

is a patience-trying operation. It has occurred to me that a small

air-pump with a supply of chloride of calcium in small tubes might

solve the problem of preserving films in the tropics. The air-pump and

supply of chloride of calcium would not be as heavy or bulky as the

tanks and powders needed for development. By means of the air-pump the

films could be sealed in tin tubes free from moisture and kept thus

until arrival at home or at a city where the air was fairly dry and

cold water for washing could be had.

While I cordially agree with most of the views expressed by Mr. Fiala,

there are some as to which I disagree; for instance, we came very

strongly to the conclusion, in descending the Duvida, where bulk was

of great consequence, that the films should be in rolls of ten or

twelve exposures. I doubt whether the four-barrel gun would be

practical; but this is a matter of personal taste.
