HAMILTON — ON TIDES OF THE BAT OF FUNDT. 3'5 



set of specimens illustrating the character of sands used for 

 makino; of bricks, and for mouldino- in brass and iron : of one 

 of these (Mr. Fellow's from Windsor) a cargo of 250 tons was 

 lately shipped to Boston for brass tube casting. Then we have 

 a set of specimens from Spriiigville, East River, Pictou, show- 

 ing the character of the rich specular and brown iron ores 

 found there, the latter I found to contain nearly sixty per cent, 

 metallic iron, and there is a specimen of the East River lime^ 

 stone from which lime is largely made and exported : very much 

 esteemed in the neighbourhood of New Glasgow. 



I am afraid my remarks are somewhat crude and imperfect, 

 but I must plead want of time to produce any thing more 

 complete, and I hope such as they are they will be of service 

 in marking the most important features in a collection of 

 minerals which I think will be found very useful in illustrating 

 the mineralogy of the Province; and of great interest to all who 

 have devoted any attention to the subject.

The general outlines of the Bay of Fundy are well knoTfn, 

 Its width, by a direct line from Brier island, the most western 

 point of Nova Scotia, skirting the south-western point of Grand 

 Manan island, to the coast of Maine, a short distance west of 

 Quoddy Head, may be called in round numbers, fifty statute 

 miles. From its mouth, it extends in a course as nearly as 

 possible, due north-east, with nearly straight shores but a gradu- 

 ally decreasing width, for about one hundred and ten miles, 

 when its waters separate into two arms known as the Minas 

 channel and Chiegnecto channel. A line drawn directly from the 

 northern to the southern shore in the immediate vicinity of cape 

 Chiegnecto, the point of bifurcation, will show its breadth to be 

 there about thirty miles. Following the more northern or 

 Chiegnecto channel a further distance of about thirty miles, we 

 find its waters again nearly equally divided. One — Shepody 

 bay — extends in a northerlv direction into New Brunswick, and
