142 YORKSHIRE NATURALISTS UNION — ANNUAL REPORT. 



continue his subscription. It may be pointed out that members on 

 election sign a form in which they undertake to pay their subscriptions 

 ' until further notice,' and that it is very needful, in order to obviate 

 all risk of misunderstanding, that such notice of withdrawal be in 

 writing, and forwarded direct to the Hon. Secretaries ; and it should 

 be further noted that any such notice expires at the end of the year 

 in which it is given. It hardly needs to be added that some such 

 arrangement be made, in order that the Union may be able to 

 discharge its own financial engagements entered into on the basis of 

 the subscriptions realising their nominal amount. 



The Publications of the Union have been as in previous years. 



The Transactions. — Part 12 was issued in January last, and 

 Part 13 within the past few weeks, both consisting of sheets of the 

 re-issue of Mr. Baker's valuable work on ' North Yorkshire : its 

 ( jeology. Climatology, and Botany,' of the latter portion of which 

 the Natural Order Caryophyllacece has been reached. 



The printers are proceeding with the sheets intended to form the 

 next instalment of 'North Yorkshire,' and the continuations of other 

 papers are in course of preparation by their respective authors. 

 Messrs. Clarke and Knubley are engaged upon the ' Birds of York- 

 shire '; Messrs. Nelson and Taylor upon the list of Yorkshire 

 Mollusca, and Rev. W. C. Hey upon that of Coleoptera — of all of 

 which sheets will be printed as soon as received from the authors. 



The Library continues to increase by means of donations and 

 exchanges. The necessity for increased accommodation which was 

 referred to in the last annual report, has been met during the year — 

 partly by the purchase of a new bookcase, but chiefly through the 

 kindness of the Committee of the Leeds Mechanics' Institution, 

 a body to whom the Union has been indebted in so many ways in 

 the past, who have placed at the Union's service a different room, 

 which affords much superior accommodation and greater convenience. 

 The consequent removal of books and other property has delayed 

 the completion of the administrative work upon which the Librarian 

 was engaged at the date of the last report. 



The Sections of the Union have carefully carried on their 

 work during the year, and it is to their efficient working that the 

 success attending the excursions has been attributable. 



Committees of Research, — This important feature of the 

 Union's work has been further developed during the past year, by 

 the appointment of a new Committee, viz., on the Erosion of the 

 Yorkshire Coast. 



The Boulder Committee has again accomplished a large amount 

 of valuable and highly-appreciated work, as shown by their Report,
