not too remote from settlements, are everywhere burned for this 

 purpose. Monroe county has long been celebrated for the 

 abundance and good quality of its lime. At Christiancy's 

 quarry, about 10,000 bushels are annually produced. The 

 Plumb Creek quarries, below Monroe, furnish a much larger 

 quantity. At Kaisinville, where the outcrop of the limestone 

 covers about 200 acres, are 13 kilns, with a capacity of 8,540 

 bushels. Supposing that these kilns burn, on an average, once 

 in three weeks, the total amount of lime produced is 145,180 

 bushels per year. Lime is manufactured at numerous other 

 points in the county. According to statistics on hand, the aver- 

 age cost of the lime at the kilns is about 5 cents per bushel. 

 It is sold for »12| cents at the kilns. Supposing the Plumb 

 Creek quarries to produce 100,000 bushels annually, and all 

 other kilns in the county 50,000 bushels, we have an aggregate 

 of 295,000 bushels, which at 12| cents a bushel amounts to the 

 considerable sum of $36,875. This lime is generally pur- 

 chased by the farmers, who carry it in wagons to the surround- 

 ing country, for a distance of 30 miles. It is generally sold by 

 them for 25 cents a bushel, making a profit to them of $36,875 

 which is likewise retained in the county. The aggregate an- 

 nual addition to the wealth of the county, therefore, fiom the 

 manufacture of lime alone, is $73,750.* 



For architectural purposes, some portions of the Helderberg 

 limestones seem to be extremely well adapted. The sills, caps 

 and water table manufactured at Christiancy's quarry, have a 

 -reputation of many years standing. They may be seen in the 

 court house in Monroe, in the new hotel, in all the new block of 

 stores en Washington street south of the city hall, in Wing 

 and Johnson's banking office, and three stores in Monroe street, 

 There is no stone which stands the weather better. They seem 

 even to improve under the influence of exposure. The distance 

 of the quarry from the railroad has, however, prevented these 

 atones from coming into general use. During 1859, twelve

 reference to selecting and burning the stone, and improving the quality of the lime.
