44 Yorkshire Naturalists' Union : Annual Report, 1920. 



viz., the two Daphnes, Celandine, Purple Saxifrage, Primrose and Violet ; 

 the promise of an early spring, but this was spoilt by the late frosts and 

 cold, wet spells which followed. Some nice weather in May, however, 

 brought Hawthorn into flower earlier than usual. It would be well 

 carefully to consider the question of weather and insects in attempting 

 to unravel the curious anomalies presented by the almost complete 

 absence of fruit from a group containing Apple, Pear, Plum, Cherry', Ash, 

 Elm and Oak, and a second group of those with abundant fruit like Beech, 

 Sycamore, Elder, Rose, Bramble, Mountain Ash, and Hawthorn. 



A carefully compiled weather report, month by month, summarized 

 in the Union's Annual Report, would be a help in such enquiries. 



There is need for careful consideration of all available facts ; but part 

 of ti\e lack of fruit may be due to the extra effort of last year, and this is 

 probably the cause of the partial absence of many of the Orchids. 

 Entomologists quote the absence of bees when orchard fruit trees were in 

 bloom, and insects generally ha,ve been adversely affected by the weather, 

 pollination being consequently uncertain. 



Botanical Survey Committee. — Mr. W. H. Burrell writes : — 

 Notes have appeared in The Naturalist from time to time, and further 

 work has been put in hand at Gormire and in Upper Wharfedale. The 

 Study of Hagg Wood, near Huddersfield, has been continued, and has 

 so far progressed that a report may be expected shortly from Mr. J. R, 

 Simpson, who, we regret to learn, has recently left the county. 



Mycology. — Mr. A. E. Peck writes : — At the Yorkshire Naturalists' 

 Meeting at Skipton in May, the Mycological Committee was represented 

 by Messsrs. M. Malone and F. A. jNIason. The meeting at Reeth in 

 May, was attended by Messrs. J. Ackroyd, R. Fowler Jones and F. A. 

 Mason. Messrs. J. Ackroyd, W. N. Cheesman, and F. A. Mason attended 

 the meeting held at Martin Beck Wood, near Doncaster, on June 19th. 



An illustrated article, entitled ' Mitrophora gigas at Forge Valley, 

 Scarborough,' by the writer, appeared in The Naturalist for July, 1920 

 (No. 762). 



At the Yorkshire Naturalists' Meeting at Kirkham Abbey on July 

 loth, the Mj^cological Committee was represented by Messrs. R. Fowler 

 Jones, F. A. Mason and A. E. Peck. See report in The Naturalist (No. 

 766). 



The Meeting, at Beverley, July 3ist-August 2nd, was attended by 

 Messrs. R. Fowler Jones and A. E. Peck. Many species of Fungi were 

 noted, particularly at Dalton Holme. See report in The Naturalist, 

 December, No. 767. 



The Annual Fungus Foray was held at Helmslcy, September iith- 

 i6th, and was well attended. For report with illustrations, by the 

 writer, see The Naturalist, December (No. 767). 



The Mycological Committee again has to deplore the loss of a member 

 by death. On July 27th, Chas. H. Broadhead died in his Goth year. 

 An article by the writer, with portrait, appears in The Naturalist for 

 October, 1920 (No. 765). 



GEOLOGICAL SECTION. 



Mr. John Holmes writes : — The Section has been represented on all 

 the long-date excursions. During Easter week the whole of the Carboni- 

 ferous .succession in the Skipton district was examined under the guidance 

 of Dr. WTieelton Hind, who also demonstrated the zoning of the Pendleside 

 Series by means of the Goniatites, a valuable piece of work, which, 

 unfortunately, i^roved to be the last of his numerous contributions to 

 Yorkshire Geology. 



Dr. Hind's loss is keenly felt by members of the Section, but the work 

 on the Pendlesides and Millstone Grit is being continued, and preliminary 

 reports by Mr. Bisat have appeared in The Naturalist. Mr. Buttcrfield's
