advice of the late Mr. A.W. Morant, M. Inst. C.E., the Borough Engineer
at Leeds, of Fryer's method of destruction by burning--that is, of the
dry ashes and cinders and the animal and vegetable refuse. The
author was Mr. Morant's assistant. The first kiln was constructed at
Burmantofts, 11/2 miles from the center of the town in a northeasterly
direction, and has been in use since the beginning of the year 1878. In
1879 another kiln was constructed at Armley Road, a mile from the center
of the town in a west-southwesterly direction, which has been in use
since the beginning of 1880.

Each destructor kiln has six cells, three in each face of a block of
brick work 22 feet long, 24 feet through from face to face, and 12 feet
high. Each cell is 8 feet long and 5 feet wide, arched over, the height
being 3 feet 4 inches, and both the bottom and arch of the cell slope
down to the furnace doors with an inclination of 1 in 3. The lower end
of each cell has about 26 square feet of wrought-iron firebars, the
hearth being 41/2 feet above the ground.

There are two floors, one on the ground level, a few feet only above the
outlet for drainage, the other floor, or raised platform, being 15 feet
above it. The refuse is taken in carts up an incline of 1 in 14 on
cast-iron tram plates to the upper floor, and deposited upon and
