Q.4.5 This is intended to locate another ridge, passing south of the last, and is composed entirely of the greenish or bluish-green diabase, only. At least I found no conglomerate during my short search here. All these two ridges are separated from each other by low nearly depressions having a direc- tion of N 38 W. Q.4.6 is not separated with the same distinct- ess from Q.4.5 indeed I doubt whether any facts can remain here to be brought out. If thus or any its directions & N 70 W. which is also the direction of that ridge of Q.4.5. became a fault depression lies in line with the northern edge of the diabase ridge, towards the south of which the conglomerate exposure of Q.4.6 are found. No diabase was visited. here. Q.4.1 Just at the landing northeast of the house. Black ish grey slate, same as at G.7.1 and Walleston Hight. Strike N 80 W. dip 70 N. to 85 N. The slate is banded towards the south. more near- sive farther inland. Then banded again. Just east of it came 20 feet is some of the rock I called massive slate, which looks like argillite. On both sides of this sheet at catified slates are much contorted and there are included contorted slates. It would be called a dyke here I think. but it will look and break like argillite. What is the meaning of the included contorted pieces. Q.4.2 Strike banded slate along shore. fine exposure. N 85 W. Dip 80 N. Warren's argillite farther is land. Q.4.3 Strike of banded rock fine long exposure. N 80 W. dip 70 N. - 80 N. Q.4.4 The slate extends out into the sea in ledges un- der the water for 100 feet at least, keeping up its strike. This is the place to go to see contorted strata still preserving their general strike with great accuracy. Dip northward 80-75. N 80 W. The contortion of the included banded slates in the more massive argillite, in very estimation one are nothing. Q.4.5 There seems to be a dike here along, the strike of the slate similar to the others at G.7.1. Q.4.6 Strike N. 80 W. Q.4.7 Strike N. 85 W. Dip 80 N. Dike there. The same
