SCIENTIFIC SURVEY. 35 1 



The rocks all the rest of the way from the junction of the two 

 branches to township No. II, the limit of our last year's explora- 

 tions, are mica schist, the same as that described between No. 11 

 and the mouth of Little Black river. In the north-east corner of 

 No. 9, R. 17, the dip is about 15° south-easterly. In the south 

 part of No. 11 the dip is 8° higher. Terraces are generally very 

 scarce upon the river St. John above the mouth of Little Black 

 river, but very handsome ones are often seen for two or three miles 

 of its course below the mouth of the north-west branch. The strias 

 run north-easterly down the river, very much in the fashion of a 

 glacier. In No. 11 we noticed a boulder of the coarse conglomerate, 

 24 feet in diameter. Although we arrived at the Seven Islands' 

 farm on the 30th of May, we passed two large snow-drifts within 

 ten miles of the buildings. This fact shows the lateness of the 

 spring in this part of the State, yet the crops had all been planted 

 when we arrived at the farm. There are probably few years when 

 snow cannot be found on the ground in this region in every month 

 of the year except July, August and September. 



Geology of the Alleguaah Waters. 



Our route now lay from the Seven Islands' farm to Chamberlain 

 lake, or the same route we travelled over the previous year. 

 Therefore we will not generalize concerning this region, and will 

 now notice only some corrections and additions to our last year's 

 report. Between the rivers St. John and Alleguash the rock 

 seems to be entirely mica schist. . Three miles east of the St. John 

 the schists dip 80° S. E. At the line between ranges 14 and 13, is 

 a band of clay slate with perpendicular strata. But half a mile to 

 the east the mica schist appears again, though highly argillaceous 

 in its character, with the strike N. 55° E. 



At the carry below Churchill dam the argillo-micaceous schist 

 dips 60° N. 20° W.; hence we do not feel satisfied that all this re- 

 gion should be ranked as clay slate. Trap and silicious slate were 

 found upon a small island near the McCatherty farm, in Churchill 

 lake ; and on the east shore of the lake a very coarse conglomerate 

 occurs, dipping 12° N. 5° E., whose constiuents are mostly peb- 

 bles of silicious slate. This is evidently a newer rock than the 

 schists and slates heretofore described. Near the south end of 

 Churchill, "similar conglomerates occur, dipping, say 50° N. W. 

 An expedition from here to Spider lak-e revealed nothing of inter- 

 est. There are no ledges upon the lake or its thoroughfare.
