determine their relative value under Hawaiian conditions. Tt is a 

 crop of very quick growth in this climate, and the number of crops 

 harvested annually ranges from twelve in the most favourable situa- 

 tions to six at an altitude of 4700 feet (p. 14), The soy bean is 

 recommended as one of the most desirable crops to grow on account of 

 the nutritive value of the foliage, its early maturity and heavy seeding, 

 together with the highly concentrated value of the crushed or ground 

 bean for both feeding and culinary purposes (p. 23). It is alsO' a good 

 subject for green manuring. It is stated that in Japan and other 

 Oriental countries this crop is responsible to a greater extent than 

 almost any other for the maintenance of their soil fertility (p. 24). 

 About 100 varieties have been tested at this Station. — A. P. 



Leopard Moth, The. By W. E. Britton and G. A. Cromie 

 {U.S.A. Exp. Stn., Conn. Bull. 169; Nov. 1911; 8 plates, 6 figs.).— 

 The larvae of the Leopard Moth {Zeuzera pyrina Linn.) cause much 

 damage to shade trees by boring in the branches just under the bark 

 and cutting large galleries, often across the grain, thus girdling them. 

 Dead branches in the tree-tops are a sign of attack. The female moth 

 lays eggs in crevices in the bark or near buds about July, and the 

 larvae hatch in a few days. During October the borers go deeper into 

 the wood and remain through the winter. They pupate in their burrows 

 the second spring, and before the moth emerges the pupa works itself 

 partly out of the opening and the adult flies away, leaving the empty 

 case protruding from the burrow. 



Eemoving infected branches; injecting carbon bisulphide into the 

 burrows and stopping the opening; probing with a hooked wire for the 

 larvae, are some of the methods of control. — V. G. J. 



Lilac, To Force. By A. Buyssens {Rev. Hort. Beige, p. 229; 

 July 15, 1911 ; plates). — A description of the three methods of forcing 

 lilac for cut blooms at Christmas and through the winter, employed 

 on a large scale in Belgium. The plants, specially grown and trained? 

 for the purpose, are either lifted and planted out in forcing-houses, or 

 movable span-roof hothouses are place? over beds of them in their 

 growing positions, or the plants are forced in pots. Minute directions 

 are given for each oi these methods. The varieties forced in Belgium 

 are principally ' Marie Legraye ' and ' Souvenir de Louis Spath.'
