Smith : Cryptogams in the Grimsby District.

a subject, but the reader has to be content with part of one 

 page, in spite of the fact that so very Httle has been written on 

 the glacial remanie of this district. 



Under the head of the ' Sands and Gravels of the Vale of 

 Pickering,' it is stated, 'it is possible that these Gravels' (i.e., 

 the Hutton Buscell Gravels) ' are the remains of an old raised 

 beach ' ; these beds are also referred to on page 99 under the 

 head of 'Physical Structure,' where reference is made to 

 Professor Kendall, attributing ' deltaic ' origin to these Gravels, 

 and the writer disagrees with this theory, but waives discussion 

 in this work, although it is difficult to see why the ' raised 

 beach ' theory is less controversial than that of their ' deltaic ' 

 origin, and there certainly seems to be a preponderance of 

 evidence in favour of the latter. 



The description of the diversion of the Derwent and the Vale 

 of Pickering river is very ably written, but the reference to the 

 thicknesses of the Boulder-clay and height of Glaciation is 

 somewhat difficult to understand. 



The printing and general get-up of the work is very good 

 and a marked advance on its predecessor (except as regards the 

 tissue paper cover), but the memoirs of the Geological Survey 

 might be improved in appearance if funds permitted an idea or 

 two being taken from the U.S.A. Memoirs. 



This new and enlarged edition will be a great boon to all, 

 and especially local Geological students, and cannot fail to give 

 a considerable stimulus to the study of the Geology of Scar- 

 borough and district. C. 



CRYPTOGAMS IN THE QRIMSBY DISTRICT. 



A. SMITH, F.L.S.. F.E.S. 



With a view of obtaining further notes on the cryptogams of 

 the area, Mr. J. Reeves and myself visited Roxton Wood, 8th 

 October 1904, working the portion situated in the Parish of 

 Brocklesby. There are numerous species of trees, but chiefly 

 Fir, Pine, and Oak, the latter of which are very much galled; 

 millions of the tiny discs of the spangle gall lie on the ground 

 and among the leaves beneath the trees. The wood is of the 

 damp kind and very prolific in flowering plants during spring 

 and summer, and is a fairly good locality for Fungi, a quantity 

 of which was gathered and sent to Mr. Charles Crossland, 

 F.L.S., whose kindness in naming the species we beg to ac- 

 knowledge. .
