344 BOARD OF AGRICULTURE. 



Seboomook lake, no ledges are seen, the banks being alluvial, and 

 the meadows extensive and fertile. The excellent character as- 

 cribed to the country between Chesuncook lake and the North 

 Branch mountain for agricultural purposes, by Mr. Geo. L. Good- 

 ale, we can fully endorse — and wonder that it has for so long a 

 time escaped the notice of settlers. 



Between the Carry farm and the mouth of Seboomook Meadow 

 brook in the township of Seboomook, we have not explored the 

 west branch, but know that many ledges occur upon this part of 

 its course, since there are falls in the river. On the east side of 

 Seboomook Meadow pond, are a few ledges of a micaceous appear- 

 ing schist, like one at the north-west arm of Moosehead lake, and 

 also on the north-west carry. No ledges were seen upon the west 

 branch of the Penobscot till we had proceeded about two and a 

 half miles into Plymouth (or Boyd.) This rock is an indurated 

 schist, of a slightly hornblendic appearance. It forms a low ridge 

 running across the valley transversly, and reminds one of the 

 indurated belts of schist frequently found in a talcose region. The 

 dip is 85° N. W. At Gulliver's falls other ledges show them- 

 selves, with strata dipping 56° S. 60° W. The rock is a mica 

 schist, passing gradually into the variety just described. These 

 falls are very strong rapids, which it was necessary to carry by, 

 and they are near the mouth of Gulliver brook. 



In Pittston the tough variety of schist reappears, running appa- 

 rently N. 65° E. with vertical strata. In this township the west 

 branch of the Penobscot divides at the "Forks" into the south- 

 west and north branches. About a mile below the Forks the mica 

 schist dips 60° N. W. Upon the ledges are striae running S. 28° 

 E., or in the direction of the valley. Possibly they are glacial, 

 and are connected with those at the mouth of Rag Muif. More 

 mica schist ledges appear at the Forks. Ledges must be very 

 abundant at the " Canada falls" upon the south-west branch, three 

 or four miles above the Forks, as the river falls many (some say 

 90) feet perpendicularly, but we had no time to explore them. 



In the edge of township No. 3, at the mouth of Lane brook, are 

 many boulders of quartz containing carbonate of iron and other 

 minerals. Boulders of mica schist contain pyrites. These frag- 

 ments reminded us of an auriferous region, and consequently our 

 long suffering tin pan was brought into requisition to wash for 

 gold. But not finding any of the precious metal after a couple of
