Berry' (Shepherdia argentea, syn. Lepargyrcea argentea) is useful both 

 for its fruits (which make excellent jelly) and for ornament, but un- 

 fortunately the branches are too thorny to allow of the fruit being readily 

 picked. It is hoped that cultivation may obviate this difficulty.

Shrubs, Pruning" Hardy. By J. Clark (Garden, No. 1,595, 

 p. 389, 14/6/1902; No. 1,596, p. 405, 21/6/1902; No. 1,597, p. 428, 

 28/6/1902). — The correct time to do this most important garden work is 

 not widely known ; it of course depends upon whether the shrub flowers 

 upon the current year's growth or that of the past year. In this article 

 instructions are given how to proceed with all the most important shrubs.

Skimmias. By J. Clark (Garden, No. 1,589, p. 287; 3/5/1902).— 

 Describing several varieties of this shrub. As a plant for town districts 

 the Skimmia is not to be surpassed, as it withstands both smoke and dust 

 well, and will flower and fruit freely under conditions which are very 

 trying to many plants. — E. T. C. 



Slugs, Detergent for (Rev. Hort. p. 249 ; June 1, 1902).— Wash 

 walls with a solution of lime and sulphate of copper, and dust infested 

 spots with lime in powder, or a mixture of sulphate of iron and sand or 

 dry soil.— C. T. D. 



Slugs that " Spin " Threads. By W. M. Webb (Gard. Ghron. 

 No. 821, p. 219, fig. 74 ; Sept. 20, 1902).— Many, if not all, of our British 

 slugs have the power of letting themselves down from a height by 

 means of a thread of the mucus which they so freely secrete, and 

 they are also able to ascend by the same. The figure shows two slugs, 

 one ascending and the other descending by means of a thread of mucus.

Sophro-Cattleya x Nydia (Cogniaux in Diet. Icon. Orch., S.-C. x 

 pi. 1 ; 6/1902). A hybrid raised by Messrs. Charlesworth & Co., of Brad- 

 ford, out of S. grandiflora by C. x calummata, and first flowered in 1901 

 Flowers deep rosy-carmine, faintly dotted with purple ; habit of growth 

 and form of flowers similar to the Catthya parent. — C. C. H. 



Spraying Orchards for the Codlin Moth. By Fabian Garcia 

 (U.S.A. Exp. Stn. New Mexico, Bull. 41 ; March 1902). — In this region 

 it is found that the worms enter the Apple from the side — unlike in the 

 Eastern States, where they mostly enter at the calyx end. During 

 good crop years it is found necessary to spray more than three times ; it 

 is found best to begin by spraying the topmost limbs, working down 

 through the centre of the tree to the outer and lower limbs, especially in 

 heavily foliaged trees. The tree should be wet all over, though not 

 necessarily dripping. Of the nozzles the "Bordeaux " was found to give 

 best satisfaction. 



W'hite arsenic, in the form of arsenite of lime and soda, is found to 

 be a purer and cheaper poison than Paris green. Lime is used to keep it 

 from burning the foliage.
