484 JOUENAL OF THE ROYAL HORTICULTURAL SOCIETY. 



the Department of Woods and Forests in France to protect historic and 

 remarkable trees. Circulars are being sent out to all local forest agents 

 in France and Algeria pointing out the value, both on aesthetic and 

 sentimental grounds, and as bringing visitors into out-of-the-way places 

 which they would not otherwise visit, of trees either remarkable or 

 beautiful in themselves or possessing historic or romantic associations. 

 These agents are called upon to register all such trees which may be 

 found in their district, and to record what it is which makes each indi- 

 vidual remarkable. In future it is to be impossible to destroy one of 

 these registered trees without a special permit from the Department, 

 which will only be given on very sufficient grounds. — M. L. H.

Truck Crop Investigations. By F. H. Chittenden, Sc.D. 

 {U.S.A. Exp. Stn., Virginia, Bull. 2; Sept. 1909; 1 plate, 11 figs.).— 

 This bulletin describes, among other items, certain pests peculiar 

 to the cabbage crop, including the cabbage aphis (Aphis hrassicae 

 Linn.), the imported cabbage worm [Pontia rapae L.), and the 

 cabbage looper (Autogmpha hrassicae Riley), with remedies for their 

 prevention and destruction. 



Kerosene emulsion prepared by combining 2 gall, kerosene, 1 lb. 

 hard whale-oil soap, or 1 quart of soft soap, with 1 gall, of hot water. 

 The whole diluted with 10 to 20 parts water, applied in a mist-like 

 spray, is the most efficacious remedy for aphis. With regard to the 

 cabbage worm, the best remedy is an arsenical wash, either Paris 

 green or arsenate of lead, applied when the plants are first set out, 

 with other applications as required until the heads are about two-thirds 

 formed, and even later, as the poison disappears from the plants almost 

 completely in three or four weeks. — V . G. J. 



Tunisia, Fruit-growing" in. By M. L. Guiblochon (Jour. Soc. 

 Nat. Hort. Fr., ser. iv., vol. xi. p. 505; Atig. 1910). — An account of 

 the present state of the fruit-growing industry in Tunisia. The colony i 

 contains regions with varying climates, suited respectively to the culti-| 

 vation of all the fruit-trees known to temperate countries and of several i 

 belonging only to the Tropics. Statistics of production and export are; 

 given here, and with the growth of the native and European populatioasj 

 of the Colony the figures inspire great hopes for the agricultural andj 

 horticultural future of the country. — M. L. H. j
