Larch Case-bearer, The. By G. W. Herrick (U.S.A. Exp. Stn., 

 Cornell, Dep. Entom., Bull. 322, Nov. 1912 ; 15 figs.). — The larch case- 

 bearer [Coleophora laricella Hbn.) is a European insect. It is a serious 

 pest to the forest larches in Germany, was introduced into Great Britain 

 with the larch, and later on found its way to America, where it works 

 considerable havoc among both European and American larches. 



Lime-sulphur seems to be an effective remedy when applied as late 

 as possible in the spring, before the buds start growing. — V. G. J. 



Larkspurs, Analysis of some Wyoming. By S. K. Loy, F. W. 

 Heyl, and F. E. Hepner (U.S.A. Exp. Stn., Wyoming, Ann. Rep., 

 1912-13, pp. 7Z~79)- — Considerable economic loss is caused in this 

 State through poisonous plants, of which the larkspur genus ranks 

 second in importance, the most poisonous species being Delphinium 

 elongatum (glaucum), D. Nelsonii, and D. Geyeri. This paper gives the 

 proximate analyses of the different parts of plants of these species. 

 An intraperitoneal injection of '0564 gram of the alkaloid obtained 

 from the leaves of D. Geyeri as sulphate killed a guinea pig weighing 

 675 grams in nine minutes. — A. P. 



Lawn Soils and Lawns. By Oswald Schreiner, J. J. Skinner, 

 and C. C. Corbett (U.S.A. Dep. Agr., Bull. 494). — An interesting 

 treatise on the types of soil most suitable for the formation of lawns, 

 large or small, with a table of the most satisfactory grasses. 



In the second part the making and feeding of lawns are discussed, 

 the authors suggesting very high feeding indeed at the beginning, 

 500 to 1000 lb. of well-slaked lime, the same quantity of bone flour, 

 with 300 to 500 lb. compound fertilizer, also 40 to 60 loads well-rotted 

 manure to the acre. — C. P. C.

 {Beih. Bot. Cent. xxxi. Abt. 2, Heft 2, pp. 177-280; with 2 plates). — 

 This paper is a complete enumeration of the plants found by the author 

 in this district. There are critical notes on the many doubtful forms. 



New species of Sison, Achillea, and Hyoscyamus are described, as 

 well as many new varieties and combinations. 



There is also a key to the varieties of Koeleria phleoides. — G. F. S. E. 



Legumes, A hitherto unnoted benefit from the growth of. 



By T. L. Lyon and J. A. Bizzell (U.S.A. Exp. Stn., Cornell,

 contents of non-legumes is greatly increased when grown together 

 with legumes. — C. P. C.

 has been found to be readily transmissible from diseased to healthy 

 trees by inoculation.
