 May 1 6th, Swift ; May 24th, Sedge Warbler. On May 20th 

 Mr. Oxley Grabham saw six Black Terns and a pair of Tufted 

 Duck on a small lake within the York City boundary, but as 

 these birds appear at the same place every year about this date, 

 the exact locality is probably best not stated. — Sydney H. 

 Smith, York, June 7th, 1910. 



Although many migrants were rather late in arriving, the 

 nesting season appears to have been an early one. Swifts did 

 not make their appearance at Harrogate until May 17th. I 

 never knew them to be so late, the 6th of the month being their 

 usual time of arrival, and they seldom vary more than a day. —

FLOWERING PLANTS. 



Double = Flowered Variety of Cardamine pratensis. — At 

 the field meeting of the Lindley Naturalist and Photographic 

 Society on the 28th May, Mr. H. Liversedge brought some 

 excellent specimens of a double-flowered variety of Cardamine 

 pratensis which he had found at Rowley Mill, Lepton. The 

 specimens included both double white and lilac-coloured forms, 

 and had the appearance of a miniature ten-week stock. — 

 W. E. L. Wattam, Newsome. 



This form has occurred here for over twenty years. — Eds.
