390 BOARD OF AGRICULTURE. 



Later in the morning we cauglit a glimpse of another large horse- 

 back in township 28, but do not know its length. This is distinct 

 from the one described previously in the corners of Beddington, 

 29 and 22. 



The stage road passes over an interesting horseback between 

 Kenduskeag and Corinth. The road first strikes it in the west part 

 of the village of Kenduskeag, and continues upon it for three miles 

 to a cemetery in South Corhith. It appears to extend somewhat 

 further in both directions. Its general direction is north-westerly; 

 but there arc changes and curves in it, whose precise nature may 

 be ascertained by noticing upon the map of Penobscot county the 

 course of the stage road. This ridge is wide and not so high in 

 proportion to its width as is most common. It is of the whale 

 back type, like the example in Aurora. We estimate its altitude 

 from twenty to fifty feet ; and its width from six to fifteen rods. 

 It starts from the lee side of a large but low hill, and the north- 

 west end is higher than the south-eastern. A cut through it re- 

 veals a section of gravel, precisely like the ideal sketch of a horse- 

 back, on page 2t3 of our first report. 



North-west from Parlin pond there is a curving horseback three 

 fourths of a mile long. Our impression is that it is parallel with 

 the shore of the pond. 



But the most remarkable example of a curving horseback has 

 been described by Dr. Holmes in his notes upon northern Maine; 

 where is one of these ridges bent around in the form of a horse 

 shoe. He also describes another one in the vicinity of great inter- 

 est. These ridges are on the Seboois waters in Nos. and 7. 



In examining the surface geology of Kennebec river, we noticed 

 three ridges above Bingham which we are inclined to refer to this 

 class of deposits, rather than fragments of high terraces, to which 

 they are closely related. The longest one is in the Forks planta- 

 tion, between F. E. Shcpard's and J. Steward's. The shortest is 

 in Caratunk, between E. Pierce's and <t. F. Chase's. The third is 

 in Moscow, west of J. P. Emerson's. They all border upon the 

 river, upon its eastern bank, forming a high ridge between the road 

 and the river. They are designated as long hills upon the map of 

 the county (Somerset.) The longest must be at least a mile and 

 a half in length, and the shortest not over a half a mile. 



Hunters have informed us of other horsebacks in the wild lands; 

 but of them all there occurs to us now the location of only one.
