4 YORKSHIRE NATURALISTS UNION. 



It is only by the united efforts of local naturalists that we can 

 expect to acquire an intimate knowledge of the Yorkshire Car- 

 boniferous Flora. This will be apparent to anyone who has 

 collected such fossils, for special opportunities, such as driving 

 mines or sinking new shafts (when th-e best specimens are usually 

 secured), can only be known to those resident in the district. 

 Should anyone become aware of such operations, especially if 

 he is unable to collect from the debris as it is brought to the 

 surface, he would confer a great favour by kindly reporting to 

 the Secretary, Mr. W. Cash, Halifax, whenever aware of such 

 operations being carried on. 



The committee most cordially thank the many workers who 

 have already assisted them in their investigations, by submitting 

 specimens for examination. xAssistance has been received in 

 this way from Mr. W. Cash, F.G.S., Mr. J. W. Davis, F.G.S., 

 Mr. J. Spencer, and Mr. J. Binns, Hahfax ; Mr. B. Holgate, 

 F.G.S., and Mr. Tindal, Leeds; Mr. Learoyd, F.G.S., Hudders- 

 field; iMr. Gelder and Mr. Taylor, Barnsley; Mr. G. McMurtrie, 

 lately of Rotherham ; Mr. C. Bradshaw, Sheffield ; and to the 

 curators of the various public museums visited. We also thank 

 Earl FitzwilHam for kindly allowing his collection to he exam- 

 ined; and Mr. H. B. Hans Hamilton, Wentworth ; Mr. W. A. 

 Durnford, Elsecar ; and Mr. G. Carr, Low Stubbin Colliery, 

 Rawmarsh, for their co-operation. Above all are we indebted 

 to Mr. W. Hemingway, Barnsley, by whom the greater part of 

 the fossils that contribute to this report have been collected. 

 Had the committee a few as able and ardent collectors as he, 

 ere long we should have a very good knowledge of the York- 

 shire fossil plants. 



In this part of the report none of those species are in- 

 cluded which are distinguished by characters derived from 

 their internal organization, as these will be treated of separately. 

 It may perhaps be well to state here that all the specimens from 

 Avhich the records have l)een made have been examined by my- 



Geol. Trans. V.N.U., iS8S (pub. 1890).
