Migration on Lougfh Mask. 



While fishing on Lough Mask at the southern end, between the dates 

 August 19th to 23rd, 191 7, I noticed several species of birds which were, 

 I think, almost certainly migrating. The first species was the Sand- 

 Martin. On August 20th I observed hundreds tlying south, the 

 movement being particularly noticeable in the morning, falling off in 

 the afternoon, and had practically ceased by about 5 p.m. On some 

 bare rocks at the very south of the lake they were collecting in hundreds 

 while many passed on over the mountains. On the same day I saw a 

 Ringed Plover flying fairly high, and at great speed towards the south 

 and on beyond the lake. On the 21st the movement of the Sand-Martins 

 was still in progress, especially about 11 a.m. and again from 2 p.m. until 

 3.30 p.m. Many passed our boat during the latter period. The 

 movement was not so great nor so decided as on the previous day. The 

 third species noticed was the Turnstone. Five were noted at about 

 3 p.m. on August 20th, and on the following day from 2 p.m. until 2.30 

 p.m., during a heavy shower with a high wind, two rested on some rocks 

 quite close to our boat. At about the same time my brother, who was 

 in another boat, at some distance, noticed three Turnstones on rocks 

 much further south. During the above mentioned shower I noticed a 

 swift flying south and very low. Evidently the Turnstones and other 

 species were availing themselves of the lakes which form a chain from 

 Killala Bay to Galway Bay.

DECORATIVE GARDENING. 



Plant Materials of Decorative Gardening, i. The Woody Plants. 



By William Trelease, Professor of Botany in the Univer.sity of Illinois. 



Pp. 204. Sm. 8v^o. Urbana, 19 17. 1 



This little book, which will easily fit the pocket, gives in a very 

 practical and condensed form an account of the shrubs and trees from 

 all parts of the world which are cultivated for their beauty or mterest 

 in the eastern United States. As may be surmised, the contents of 

 the volume apply almost equally to our own country. Simple language 

 and simple keys are provided ; and it should be easy for anyone with 

 a smattering of systematic botany to run down a plant. The number 

 of species dealt with is 782, and a large number of varieties are also 

 included. For those who love shrubs, and cannot aftord Mr. Bean's 

 invaluable but expensive work, this booklet should have a very definite 

 value.
