Physical Geography and Geology. 



Mr. Percy F. Kendall (Owens College) writes the following : — r 

 The Saddleworth district affords an excellent illustration of a 

 geological inlier. 'Fhe Yoredale rocks and the overlying Millstone 

 Grit have been thrown into an anticlinal fold running in a general 

 North and South direction, but complicated by minor undulations at 

 right angles. From the summit of the ridge the Millstone Grit has 

 been removed, exposing the Yoredales. The Yoredale series consists 

 of Shales and Grits, the former containing intercalated bands of black 

 Limestone which are often crowded with Goniatites, Orthoceras, and 

 other fossils. The anticlinal axis coincides roughly in position with a 

 fault of small throw but extending to a distance of about twelve miles, 

 and many smaller, sub-parallel faults traverse the adjacent country, one 

 of them crossing the village of Saddleworth. The Millstone Grit 

 completely encircles the Yoredales and rises on the North and East 

 into a series of flat-topped hills presenting the features of moorland 

 scenery so characteristic of the formation. About two miles North of 

 Saddleworth is an outcrop of coal occurring as a lenticular seam in 

 the Millstone Grit. 



Botany. 



Messrs. John Whitehead (Oldham) and J. R. Byrom (Manchester) 

 furnish the following notes : — 



In the Greenfield valley the following plants occur — but it will be 

 too early in the season for most of the phanerogams — viz. : — Drosera 

 rotimdifolia, Hypeiicuin eiodes, If. d'/biuin, Rubus cha//icBinorus, Carlina.
