CHAPTER X.

_PAUL BEGINS TO UNDERSTAND._

In spite of the news of the war, which was daily assuming a more

threatening character, M. de Gandelau insisted on the works not

being interrupted; and the inhabitants of the _château_ found in

the execution of the plans prepared by Eugène and Paul a beneficial

distraction from the sad forebodings which oppressed them.

In the evening, after reading the paper, which recorded, alas! only

a succession of disasters, everyone remained silent, with eyes fixed

on the hearth; but soon, with a determined effort, M. de Gandelau

started the inquiry how the house was getting on. It was for Paul, as

Clerk of the Works, to give an account of the operations of the day,

and he began to perform his task with a fair amount of exactness and

clearness. He showed his memorandum books, which, thanks to Eugène’s

corrections, were not very badly drawn up, and which, by the help of

a daily summary of accounts, indicated the expenses that had been

incurred.

[Illustration: FIG. 25.]

The excavations had hitherto furnished enough materials to obviate the

necessity of sending for any from the neighbouring quarries. About

the 15th of September the cellar walls were already beginning to make

their plan visible, and it was time to think of the exterior plinths in

elevation, and of the cellar vaultings, for whose construction wooden

centres were required. The carpenter was therefore commissioned to send

for timber-sawyers, to convert some trunks of poplars, which having

been cut some time before, were put by for the purpose. The best part

of the wood was sawn into thin boards for battens, to be employed when

required; and the slabs—that is, the part near the bark—were cut up

for centring for the cellars. As the plans gave only two barrel-vaults

whose arches were different, the curves were soon struck out, and

the carpenter prepared the centres, which were fixed up as soon as

the cellar walls reached the level of the spring of the vaults These

centres were formed in the manner shown in Fig. 25—that is, consisted

each of a tie-piece, A, a king-post, B, two blades, C, and clips, D,

which held fast the curves formed of slabs of poplar nailed together,

as shown at E, and fixed at G and H on to the king-post by means of a

notch, F, and to the tie-piece by an iron staple. On these centres,

supported by props K, and set five feet apart, they laid a covering

composed of planks, L, 3 inches thick, to receive the vaults, which

were made of blocks of tufa extracted from the banks of the rivulet, 8

inches in thickness, with a good layer of mortar over all. The openings

for the air-holes had to be contrived in the haunches of the vault, a

piece of work which gave Paul considerable trouble—or rather, he had

some difficulty in understanding it and sketching it in his note-book;

for, as to Branchu, he did not seem to find any particular difficulty

in it.

Eugène had given the sketch for the air-holes at the same time as the

section of the plinth, 5 feet in height above the ground level.

[Illustration: FIG. 26.]

This drawing presented, in section at A, and in plan at B, the

figure 26. Eugène had to explain this sketch to his clerk-of-works,

who did not understand it at the first glance. “As the light comes

from the sky, at the mean angle of 45°, the cellars must be lighted

accordingly,” said Eugène. “The plinth consists of a course, D, half

sunk in the ground, two clear courses, E F, and a course bearing the

set-off. We give the cellar wall bearing the spring of the vaults, 3

feet. The wall above the floor-level being 2 feet, this wall gives one

foot on each side of the fixed centre-line, but as the plinth has 4

inches of projection outside, there will be 16 inches from the centre

to the exterior face of this plinth. Within, the wall descends plumb

as far as the skew-back which carries the vaults. A width of 8 inches

is needed to receive the latter. Thus, from the centre-line below the

spring of the vaults there will be 20 inches in the interior, and 16

inches on the exterior: total, 3 feet. The lower course rising above

the surface 6 inches, and the height of the plinth being 5 feet, there

remains above these 6 inches, 4 feet 6 inches, which divided by three

gives for each course 18 inches. I take the opening of the air-hole in

the second course; out of the third, I take a chamfer of 4 inches, to

admit the light, as the exterior, M, and the section indicate. I cut

the first course to a slope of 45°, as shown at I, leaving a flat, _a_,

of 12 inches, as you see in the plan. Then, behind this sill, I place

a lintel, with a chamfer in the same way, as drawn at O, and take care

to leave at _b_, two rebates of 2 inches, for casements or gratings,

at discretion. At the back of these rebates, I splay the air-hole,

which has only 2 feet 8 inches of exterior opening, to 3 feet 4

inches. I draw in section an inclined line, _m n_, 8 inches above the

lintel O, which 8 inches will be the rise of the arched opening that

will penetrate into the barrel-vault, and whose curve in horizontal

projection will give the outline X. Thus this arch, X, will receive the

thrust of the courses of the barrel-vault, and will throw it on the two

cheeks, P. Branchu will only have to mark the curve X on the covering

of the centres to form his arched opening.”

[Illustration: FIG. 27.]

It was not quite certain that Paul perfectly caught this explanation,

though repeated several times; and he did not understand it completely

till he saw Branchu construct the air-holes and the centres were

removed (Fig. 27).

[Illustration: FIG. 28.]

“I spare you the difficulties,” said Eugène, seeing that Paul was

puzzled to comprehend the construction of the cellars, “for the

structure of the vaults and their penetrations is a matter that

requires long study. We have made only simple barrel-vaults, and

you will observe that the cellar doors are all in the end walls, or

tympanums, and not in the side walls bearing the springing of the

vaults. With the difficulties, I also avoid useless expense. The

courses which form the plinth will be of hard stone, but you will

observe that, except at the angles and for the air-holes, they are

only a facing,—they are not parpings, that is, do not form the whole

thickness of the wall. We have excellent rubble-stone, which, with the

good mortar we employ, offers greater resistance to pressure than is

required to carry two stories and a roof. Letting these rough stones

tooth out on the inside we tie them better into the haunches of the

barrel-vaults (Fig. 28), and thus economise dressed stone. You will

also see in elevation, above the plinth, how we can spare dressed

stone if we wish, while preserving a perfectly sound construction. We

find moreover, on the surrounding uplands, layers of thin limestone,

which split in regular beds from 6 to 8 inches in thickness, and which

make capital range-work. We call that range, or coursed work, in

which the stone is laid with visible faces, beds, and joints somewhat

roughly dressed. This range-work facing, which presents in its way an

attractive appearance, and whose rusticity contrasts with the smooth

finish of the dressed stone, is backed with ordinary rubble walling.

Thus, in districts where stone occurs naturally of this shape in the

quarries, we get an economical building material. But it is puerile to

amuse one’s self with making thin coursed-work where soft freestone

abounds, and where it must be cut into little bits to obtain this

appearance. You will see that it is contrary to common sense to cut

great blocks of stone into little bits, and that when the quarries

supply those only, it is reasonable to employ them according to their

natural dimensions, and to adapt the construction to the nature and

height of the stones. Here we have large blocks, when we require

them, but they are not common. In short, we ought to proceed, as far

as possible, according to the nature of the materials which the soil

furnishes us in abundance.”

The drain was made, the vaults were turned; the steps down to the

cellars were laid; the plinth had risen more than a yard above the

ground. It was time to think about studying the details of the

elevations. That overlooking the garden was only roughly sketched out.

Paul was hoping that it would present a more regular appearance than

that of the entrance side. He made a remark to that effect, for Paul

had seen in the environs of Paris, many country-houses that seemed to

him charming, with their four pepper-boxes at the angles, their porch

in the very centre of the façade, and their zinc cresting on the roof.

He had too high an opinion of his cousin’s ability to allow himself

to criticise the façade of his sister’s house, as designed for the

entrance side; but in his heart he would have preferred something more

conformable to the laws of symmetry. Those windows of all forms and

dimensions shocked his taste a little. When the façade on the garden

side (Fig. 29) was sketched—a frontage which, this time, presented a

symmetrical aspect—Paul declared himself satisfied with it; and in the

evening, the family being assembled, he asked why the entrance front

did not present the symmetrical arrangements which delighted him on the

garden side.

[Illustration: FIG. 29.]

“Because,” said Eugène, “on the garden side our plan gives us rooms

which are the counterparts of each other, of equal dimensions and

corresponding purposes; while on the entrance side we have very diverse

services in juxtaposition. The question you raise, Paul, is a very

large one. Two methods may be followed. On the one hand, you may plan

a symmetrical architectural casing, in which you try, as best you

can, to accommodate the services required by a habitation. Or, on the

other hand, you may arrange these services, in plan, according to

their importance, their respective place, and the relations that are

to be established between them, and erect the casing so as to suit

these services, without troubling yourself to obtain a symmetrical

appearance. When it is proposed to erect an edifice whose exterior

aspect is destined to exhibit a grand unity of design, it is desirable

to endeavour to satisfy the rules of symmetry, and to take care that

the building shall not present the appearance of having been built

piecemeal. In a private habitation it is imperative first to satisfy

the requirements of its inhabitants, and not to incur needless expense.

The habitations of the Ancients were not symmetrical, any more than

those of the Middle Ages. Symmetry strictly applied to domestic

architecture is a modern conceit—an affectation—a false interpretation

of the rules observed during the best periods of art. The houses of

Pompeii are not symmetrical: the country-house—the _villa_—of which

Pliny has left us a complete description, did not present a symmetrical

_ensemble_. The castles, manors, and houses built during the Middle

Ages are anything but symmetrical. Lastly, in England, in Holland, in

Sweden, in Hanover, and in a large part of Germany, you may see numbers

of dwellings wonderfully appropriate to the needs of their inhabitants,

which are constructed without regard to symmetry, but which are

nevertheless very convenient and elegant in appearance, from the simple

fact that they clearly indicate their purpose.

“I know that there are many persons quite disposed to put themselves

to inconvenience every day, in order to have the vain pleasure of

exhibiting regular and monumental façades outside; but I think your

sister is not one of those persons, and therefore I have not hesitated

to proceed according to what I conceive to be the law of common sense

in making the designs for her habitation. I can fancy her asking me,

with her quiet, and slightly ironical smile—

“‘Why, my dear cousin, did you make me so large a window in this small

room? We shall have to stop up half of it.’... Or, ‘Why did you not

give me a window on this side, where the view is so pretty?’

“If I replied that it was to satisfy the laws of symmetry, she would

perhaps have laughed outright, and, _in petto_, might probably have

thought that her respected cousin was after all a fool, with his ‘laws

of symmetry.’”

“Alas!” said M. de Gandelau, “there are too many people in our country

with whom considerations of vanity take precedence of everything else,

and that is one of the causes of our misfortunes. Appearance is the

great object. Every retired _bourgeois_ who has a country-house built,

wishes to have his turrets regularly disposed at the corners of a

building, symmetrical, indeed, but in which he is very indifferently

lodged—satisfied if this inconvenient erection is called the _château_,

internal comfort being sacrificed to the gratification of exhibiting

outside bad stucco carvings, zinc ornaments on the roof, and a quantity

of nonsensical decorations which have to be renewed every spring. Build

us then, cousin, a good house, well sheltered from the sun and rain,

thoroughly dry within, and in which nothing is sacrificed to that

debased luxury which is a thousand times more offensive in our country

districts than it is in the city.”
