Stone walls are figured either by the perch or the cubic yard.

In taking off a stone foundation, it is customary to take the corners twice, that is, each different face of the wall is measured from out to out, thus doubling the corners. This makes up for the extra labor of laying up the corners.

The cost of a perch of rubble foundations laid in Rosendale cement mortar, 1 to 3, may be taken as follows:

Cut Stone. Cut stonework is figured by the cubic foot, the prices differing according to the amount of labor involved in the cutting; and this will depend somewhat upon the nature of the stone, a hard stone being more expensive to prepare than a soft one. The principal kinds of stone used in building are granite, limestone, sandstone, marble, and bluestone.

Granite. Granite is one of the hardest stones to quarry and prepare, and, on account of its cost it is not so freely used as limestone or marble. Granite in rough blocks from the quarry will cost 45 to 60 cents a cubic foot, the cutting of beds and joints will cost 25 cents for each square foot of surface so treated. If the face is pitched off to a line with rock face, it will cost 25 cents per square foot, while hammering in 8-cut work will cost 70 cents per square foot. Quincy granite will cost, in the rough, about double this, or $1.20 per cubic foot; the cutting will cost one-third more.

From this data we may deduce the following scale:

Granite, in rough blocks at quarry, per cu. ft.

$0.60

Add for beds and joints per sq. ft.

.25

Add for rock face, pitched off to a line, per sq. ft.

.25

Add for 8-cut work per sq. ft.

.70

Hence the facing of an average wall with 8 inches of granite will cost, if the stones are about 2 feet x 3 feet, or 6 surface feet in each block:

Stock, 4 cu. ft.

at .60

$2.40

Beds and end joints 2 2/3 sq. ft.

at .25

.67

Rock face 6 sq. ft.

at .25

1.50

Cost of 6 superficial ft. or 76 1/6 cents per square foot.

$4.57

If the same were finished in 8-cut work, the cost of finishing the surface would be 70 cents a square foot instead of 25 cents, making the cost per square foot 45 cents more, or about $1.21 a square foot.

Limestone. Limestone is used to a large extent, especially in conjunction with brick, for trimmings for various kinds of buildings. Limestone will cost at the quarry about 30 cents a cubic foot; this will apply to Indiana limestone only. Lake Superior redstone will cost 35 cents; Ohio sandstone, 50 cents. In estimating, about 20 per cent should be added for waste, 5 per cent quarry waste, and 15 per cent for cutting waste:

* Window Sets. A common use of limestone is in the form of window sets, consisting of a flat arch in three pieces with keystone, and a light sill, as shown in Fig. 12.

*These prices are based on a freight charge of $0.55 per cu. ft. to Boston. The freight on Lake Superior stone is .55

The rise of these caps is about 10 inches, and the rise of the sill 5 inches. These sets for an average sized window, say 4-foot opening, will cost for a 4-inch reveal $10, and for an eight-inch reveal $15.

Sandstone. The cost of dressed sandstone is about 10 per cent more than that of limestone.

Setting. The cost of setting cut stone may be taken at 15 cents a running foot for window trimmings and ashlar work, and

20 cents for platforms, water table, steps, etc. Trimming and fitting at the building will cost about 10 cents per cubic foot.

The foregoing prices are based upon quarry-men's wages at $2.50 per day, and stone cutters' wages at $4.00 per day.

Much of the cutting and finishing of stone is done by machinery, so that the question of wages will not enter into the preparation of the stock so largely as in many other branches.

Marble. A more expensive stone to use is marble, which can be obtained in a variety of colors, in different parts of the country. The price of marble differs in different localities but for general purposes may be taken as about double the figures which we have quoted for limestone.

Bluestone. Bluestone is used in the East mainly for flagging, copings, etc., but is used to a considerable extent for building, in Central and Western sections. The price of bluestone flagging 3 inches thick with trimmed joints and face planed and dressed, will be 65 cents a square foot; with natural face, 35 cents to 45 cents. Bluestone ashlar 8 inches thick with natural face and dressed joints, will cost $1.00 per square foot, and 15 cents a square foot for setting.

Seam-Faced Granite. In some localities granite, lying in upturned strata with open weathered seams, is to be obtained. This is used for facing walls in ashlar work, being set on edge in the wall with the seam-face showing; this will cost, in place, 4-inch to 8-inch thick, from 60 cents to 75 cents a superficial foot.
