Below tills last bed, the Coal measures continue to occupy the 

 country for some distance, and a bed 4 feet thick, the " Gardener 

 Coal," occurs 330 feet lower. At a distance estimated by Mr 

 Lyman at 2400 feet below the Long Beach Seam, or about 2130 feet 

 below coal No. 29, mentioned above, occurs a bed of good coal, three 

 feet eight inches and a quarter in thickness, oi", including a clay part- 

 ing, which appears in some portions, but not in others, four feet one 

 inch and a half. It is called the " Tracey Seam." Another seam is 

 indicated in Mr Poole's and Mr Mosely's plans, between the " Tracey " 

 and seam 29 above, and 435 to 460 feet above the former; but I have 

 no information in respect to it. The Tracey bed is now worked on the 

 peninsula between Cow and Mire Bays, and is the most eastern coal 

 worked in this coal-field. To the southward of it, however, and at a 

 distance representing at least a thousand feet of beds, there is said to 

 be still another coal known as the " Spencer Seam," before we reach 

 the beginning of the Millstone-grit series, which would thus seem to 

 be at least 4500 feet below the newest beds seen near Glace Bay. 



An important question arises here as to the equivalency of any of 

 these beds with the Coal measures of North Sydney. Mr R. Brown, 

 in the remarks prefixed to his section of the Sydney Coal-field in 1849, 

 states his belief that the beds at Glace Bay are newer than those of 

 North Sydney. Mr Lesley, on the other hand, regards them as equi- 

 valent. After a careful comparison of the several sections, I confess 

 that I think the view of Mr Brown the more probable ; more espe- 

 cially as it places these beds more intelligibly in relation with the 

 members of the Lower Carboniferous seen farther inland, and with the 

 other coal-fields of Nova Scotia. From Mr Bi'own's section, it would 

 appear that the Sydney main coal is only about 800 feet above the 

 beginning of the Millstone-grit formation ; and one considerable bed, the 

 Indian Cove seam, of 4 feet 8 inches in thickness, occurs in this interval 

 with a thickness of 350 feet between it and the Millstone-grit. Now, 

 as the latter formation is not brought to the surface by either of the 

 anticlinals between Sydney and Mire, and does not appear for some 

 distance up Mire Bay, it seems plain that the only beds in our sections
