3 x 4 x 9 inches weighs about 0 pounds.

Loss in broken and rejected bricks, from 2 to 4 per cent.

tProf. Ira 0. Baker, in 'Toads and Pavements," says: "The organization of a paving gang is usually about as follows: 1 Man in charge of spreading the sand cushion....$ 2.50 1 Helper on the sand cushion 1.50 6 Men wheeling blocks from wagons 9.00 4 Men setting blocks 10.00 1 Man sweeping pavement and filling joints with sand 1.50 1 Foreman in general charge 5.00 Total per day of 10 hours $29.50 "This gang should at least lap 1,000 square yards in 10 hours." Expert 15,000 (small) in ID hrs.

Average man _8,000 to 10,000 (large) in 10 hrs.

Expert 10,000 to 12,000 (large) in 10 hrs.

Cost of filling joints in a brick pavement: With sand 2c. sq. yd.

With tar 10 to 120. sq. yd.

With Portland cement grout, mixed in small Into 10 to 120. sq. yd.

With Portland cement grout. uniform brick.

thin joints ... . . or 10c. sq. yd. Cost of expansion joints: 1 gal. tar at Or. for each 5 or 0 eq. yds. of pavement sq. yd. Add, also, cost of administration, tools, profits, etc. If brick blocks are piled at side of street,/add 2 or 2 cents per square yard.

The prices of labor and material will vary from the above according to the locality, and this outline may he changed to suit local conditions.

Other estimates taken from various sources give the following costs, which may be used in checking detailed local estimates: Brick work only, 15 to 20 cents per square yard.

Brick, 4 inches of brick on 3 inches of sand, 65 to 85 cents per square yard; 4 inches of brick on 6 inches of natural cement concrete and 11/2-inch cushion of sand, $1.20 to $1.60 per square yard: sidewalks, 2 inches of brick on sand, 50 to 80 cents per square yard. Tables XXVII and XXVIII may he used in computing the number of bricks required for the foundation and top courses respectively of pavements.

The following analysis of the cost of brick paving is taken from "Engineering News." July 24, 1902: "The following is a summary of {he cost of paving with brick laid on edge, wages being 25 Cost of Brick Paving Cost per Square Tarr 57 'Tavel," at $10 per 11. $0.57 Hauling miles over earth roads .06 Laying pavers, including labor of grouting .08 0.18 cu. ft. = 1/150 cu. yd. of grout" .05 1/36 cu. yd. sand cushion at $1.08 a en. yd. .03 Planks to protect concrete .01 Total net coat 30 80 Add about 19 per cent for profit .15 Contract price $0.95 .1 part Portland cement to 2 parts sand. "To this, of course, must he added the cost of grading and cost of concrete foundation."
