Agr. W. I. vol. ix. No. 3 ; 1908, p. 265).— Detailing the results of experi- 

 ments in the extraction of essential oils consequent on the erection of a 

 small still at the Botanic Station, Antigua, ending with the suggestion of 

 a simple form of still for the extraction of essential oil from such material 

 as lemon grass, bay leaves, and the like. — M. C. C.

Evergreen Trees of Colorado. By B. 0. Longyear (Colorado Agr. 

 Exp. Stn., Bull. 130 ; May 1908). — This is by far the most exhaustive 

 account of the coniferous trees of Colorado that has yet appeared, and the 

 beautiful and accurate illustrations still further add to the general value 

 of the work. 



To English growers the work must also appeal, for every species thrives 

 well in this country. Colorado possesses five species of Pinus, two 

 spruces, two silver firs, two junipers, and the now well known and justly 

 valued Douglas fir. 



The cone of the foxtail or hickory pine (Pinus aristata) can hardly 

 be distinguished from that figured in the Gardeners' Chronicle some years 

 ago as collected by the present writer near Berkhamsted, in Herts. It 

 is truly a curious and interesting species. The nut pine, the seed of which 

 is so largely used in confectionery in this country, is well described and 

 illustrated.— A D. W. 



Ferns, Effect of Light upon the Germination and Gameto- 

 phyte Of. By A. C. Life (Bep. Miss. Bot. Garcl. 1907, pp. 109-122). 

 — Spores, it is found, do not as a rule germinate in darkness. Weaker 

 light produces ribbon-like prothallia, stronger light heart-shaped ones. 

 Weak light inhibits the production of archegonia and favours that of 

 antheridia. A history and bibliography of the question is given.

Forest Planting Leaflet (U.S.A. Dep. Agr., Forest Service, Circ. 61, 

 revised edition). — There is much information of a sound and practical 

 nature contained in this leaflet, not only as how most successfully to 

 transplant forest trees, but also as to the proper season, puddling, heeling 

 in, treatment before transplanting, and transplanting in nurseries. To 

 those about to form young plantations in this country the information 

 should not come amiss, for the various operations are well and clearly 

 described. — A. D. W.

 Problems (U.S.A. Dep. Agr., Forest Service, Circ. 36 ; 4th edition).—
