 Another bog (S) on the property of J. B. Collamer, in the north- 

 east corner of the town near the Greece line and on the lake 

 shore, stands as follows: at the outside' is an area of muck, 

 within this, an area of peat and then reed-grown water. 



A peat deposit (9) on the land of Wayland A. Keyes, in the 

 eastern part of Rush near the town line, was worked some 

 years ago, for private use by Hallock Bros. 



In the town of Mendon in the region of the Mendon ponds, 

 are several bogs. One (10) , a closed bog, known as Huckleberry 

 swamp, is on the farm of Judson Howard. This is a typical 

 sphagnum swamp, being surrounded by a narrow ring of mud 

 and water, and higher in the center than at the sides. Mendon 

 pond (11) and Mud pond (12) are surrounded by a deposit of muck, 

 within which is an area of peat, seemingly floating on the water, 

 as it will spring and rock under foot. Within this is open 

 water. Round pond has been divided into two ponds by the 

 formation of a bar of peat. This peat or vegetable matter, for 

 very little earthy matter can reach the center of the pond, is 

 gradually encroaching on the open water and will eventually 

 claim the whole pond. Many of the bogs of the vicinity prob- 

 ably originated in this way. One (13) of this nature is located on 

 the property of Morey C. Garland, in the southwest corner of 

 Pittsford. 



Just north of Mendon pond, in the town of Pittsford, is what 

 is known as the Beaver meadow (34) . An attempt was made some 

 40 years ago, to use the peat from the portion lying or the farm 

 of Robert Hopkins. According to S. J. Crump, of Pittsford, who 

 has examined this deposit, there are about 2 feet of soil, 3 feet 

 of pure peat, under this a thin layer of a black, carbonaceous, 

 jellylike matter which hardens on drying, then a shell marl 

 which has been penetrated to the depth of 2 feet. Conspicuous 

 in the marl are the shells of the common pond snail, Limnea 

 st agnali s. 



Peat occurs at one or two points in the troughlike lagoon area 

 on the south side of the Ridge road. The peat from one of these (15)
