mately the same time is required for cooling as for burning. 

 When a kiln is cooled, the pipes are wheeled into an open yard. 



The company has 10 square down-draft kilns. Soft coal is 

 used, about 100 tons being consumed in a week under the boilers 

 and in the kilns. 



Sixty men are employed the year through. Last year the fac- 

 tory was run for 49 weeks, three weeks being lost owing to the 

 lack of coal, due to delay of traffic, from the heavy snows and 

 thaws. 



The output for the last year was about 600 carloads, seven 

 kilns, holding two carloads each, being burnt each week. 

 Twenty per cent of this is consumed locally. 



The Standard Sewer Pipe Co., on Lexington avenue, office, 8 

 Caledonia avenue, uses clay obtained mainly from two beds in 

 Chili, one (5) just west of the Maplewood brickyard, the other 

 iy 2 miles farther south and just beyond Black creek (6 >. Both 

 beds are connected by sidings with the Buffalo, Rochester & 

 Pittsburg Railroad, which runs past the works. The bed at 

 Maplewood is a red clay about 3 feet deep, underlain by an 

 argillaceous gravel; the other is a light colored clay about 4 

 feet deep and underlain by quicksand. The clay is dug up with 

 spades. The company also uses the New Jersey fire clay. The 

 process of manufacture is the same as that of the Rochester 

 Sewer Pipe Co. This company has five square and four round, 

 down-draft kilns, with six to eight fireplaces each, some fired 

 on grates, others on the floors. The fires are separated from 

 the contents of the kiln by fire walls. 



This year the company has been mainly making conduit pipes 

 and has a double conduit press, or one feeding two dies, one on 

 each side. Six hundred carloads of material have been put out 

 during the past fiscal year. Local trade takes about one tenth 

 of the output. 



Lime industry 



In Monroe county there are at present but three limekilns 

 burning : one (1) in the southern part of Rochester on the corner of
