368 BOARD OF AGRICULTURE. 



at the foot of almost every lake (and they are not a few) all over 

 the wild lands — or at least, where there is a pine log to be floated 

 on its waters. We saw no rock in place on our way, but occasion- 

 ally passed moderate sized boulders of a grey compact sandstone. 

 We found the lake to be about four miles in length, and its shores 

 deeplj'^ indented with coves and creeks and its waters, for the most 

 part, very deep. There are several islands in it, and on a part of 

 its eastern shores, and on the islands ledges crop out, some of them 

 forming bluffs of considerable height. After furnishing ourselves 

 with such specimens of the fish and reptiles we came in pursuit of, 

 we landed on the shores and islands to obtain specimens of its 

 geology for your inspection. 



They are of three varieties. On the eastern shore, as you pass 

 up the lake, are found ledges of unstratified syenitic rock — next fur- 

 ther north, on one of the islands, is argillaceous slate full of seams 

 and joints, the strike or range north-east, dip perpendicular, and 

 next north of this silicious slate having the same range and dip as 

 the other. 



I thought it probable that the sandstone might be found in place 

 here as indicated by boulders which we had passed below, but saw 

 nothing of the kind. I was afterwards told by a person who had 

 spent considerable time, a few years ago in the neighborhood of 

 the lake, "prospecting for timber," that on a highland called 

 " Owl's head," not far east of the lake, he found rock that " con- 

 tained shells of various kinds." This was probably the sandstone 

 in question. 



Seboois Lakes. 

 Eeturning from Scragly lake to the Seboois House, we com- 

 menced preparations for an exploration up the Seboois lakes, and 

 accordingly made arrangements with Staples, who had canoes in 

 those waters also, and who was well acquainted with the haunts 

 of some of the wild animals we were desirous of obtaining, to act 

 as guide and woodsman for us. As his canoe was at the Seboois 

 dam, and from the position of the lakes above, and the direction of 

 them from Seboois House, I thought it might be a saving of time 

 to dispatch Messrs. Staples and Besse to the dam for the canoe 

 while Knox and myself took a " bee line" for the foot of the first 

 lake, and wait until they came up the river to that place. In this 

 calculation however, I was foiled, by the fact being made known 

 to us that the invariable accompaniment of a horseback, viz., a bog
