Mycology. — Mr. A. E. Peck writes : — No meetings have 

 been held, but Mr. Harold Wager has been collecting Fungi 

 in Litton Dale, and has been investigating spore colouration 

 in the Fungi. He has also made some experiments on the 

 colouring matters of Lcptonia incana. Yorkshire Mycology 

 suiters severely by the decease of Charles Crossland (December 

 Qth, 1916), see The Naturalist, January, 1917, and ' Transac- 

 tions of the British Mycological Society for season 1916 ' (Vol.

 British Mycological Society for Season, 1916 ' (Vol. \ ., Part 3). 



GEOLOGICAL SECTION. 



Geological Section. — Mr. John Holmes writes : — Al- 

 though there has been no opportunity for combined effort, 

 much work has been accomplished by individual members of 

 the Section during the year. Dr. Woodhead has made a 

 valuable contribution to the glacial geology of Calderdale by 

 his observations on the excavations near Huddersfield. Mr. 

 Gilligan has described some interesting minerals found in the 

 Millstone Grit. The revival of the glass industry in South 

 Yorkshire has stimulated the study of sands, wdthin the county 

 and elsewhere. The materials used for refractories in the iron 

 and steel industry have also received attention. 



Jurassic F^lora Committee. — Mr. J. J. Burton writes :— 

 All operations on a systematic scale have been suspended for 

 the present. Owing to the war, the difficulty of travel, the 

 many claims upon the time of members of the Committee and 

 the quantity of material not fully examined, it is not anticipated 

 that much more can be done for some time. 



Coast Erosion Committee. — Mr. J. W. Stather writes : — 

 The sea is still eroding the Yorkshire coast, and falls of cHff 

 have occurred, but for obvious reasons no accurate information 

 can be given on these points just now. 



Glacial Committee.— -Mr. Thomas Sheppard,M.Sc., reports 

 that Mr. T. Crowder of Bardney, Lines, informs him that 

 during some excavations in the main street at Bardney a 

 little while ago, an enormous block of stone was discovered at 

 about a depth of 2 feet from the surface. It measured 10 

 feet long, by 6 feet wide, by 2 feet deep. It was a rough
