REPORT OF THE DIRECTOR AND STATE GEOLOGIST 1902 1'89 



and one (3) in the town of Brighton, about a mile east of the vil- 

 lage, on the south side of the Brighton-Pittsford highway. 



The one in Rochester is owned by Lamson & Leason, who work 

 it themselves under the name of Hurd Lime Kiln Co. They have 

 a single center-draft kiln, with four fireplaces, two on a side. 

 The kiln, with a capacity of 600 or 700 bushels, is filled from a 

 bucket raised by steam. Soft coal is used in burning. The rock 

 is obtained from J. B. Nell is who quarries it a little farther west 

 on Cottage street from a level which is but a few feet below the 

 zone of silicious concretions carrying the Guelph fauna. It is 

 mainly made up of drifted bryozoan fragments. 



The amount of stone used during the last year, was 429 loads, 

 or about 107 cords. A cord of Lockport dolomite weighs, ac- 

 cording to Lauer & Hagaman, 14,000 pounds. Mr Lamson says 

 that two pounds of stone when burned make one pound of lime. 

 From this it is estimated that the output of lime was about 

 10,700 bushels (70 pounds to the bushel). Besides selling quick- 

 lime in the ordinary commercial form, the company grinds part 

 of it with millstones, for use in the glass works of F. E. Reed, 380 

 Plymouth avenue. Three loads of about 37 to 38 hundredweight 

 each are used in a week. 



The two remaining kilns burning belong to the Rochester Lime 

 Co. of 209 West avenue, Rochester. The principal proprietor is 

 Mr F. C. Lauer, of Portland avenue. The kiln in Brighton is 

 known as the May kiln and is in charge of Charles Rambert. 

 That in Gates is known as the Snow kiln, and is in charge of 

 R. Wakelee. At each of these factories there are two kilns, each 

 having four fireplaces, two on opposite sides, and a central draft. 

 Their capacity varies from 300 to 500 bushels. Wood and coal 

 are used in burning. The stone is drawn in cars, by steam power, 

 up an inclined track to the top of the kiln. When first started, 

 the kiln runs from 16 to 24 hours before the first draw of lime can 

 be made. It can then be filled at the top as fast as the lime is 

 drawn from beneath. Ten to 12 'men are employed at the Snow 

 kiln and 8 to 10 at the May kiln. This, of course, does not 

 include help drawing in lime or distributing it. During the last 

 year 150,000 bushels were sold at 25 cents a bushel. A consider- 

 able part of the lime is shipped out of town.
