m :';!''< I i ■ ' states that seeds treated in this way germinated more quickly 

 and more regularly, and gave rise to more vigorous plants, than those 

 raised from seed not so treated, which plants were also freer from the 

 attacks of vermin. 



It ia not advisable to make sowings with seeds which have passed the 

 average period of their germinative power. A list is then given of 36 

 vegetables, with the average germinative period of each.— IF. C. W. 



Vine, Moth of the, To destroy. By J. Perraud (Com}). Bend. 

 June 13, 1903).— The moth called Tortrix Pilleriana is said to be, after 

 the Phylloxera, the most destructive of insects to the Vine in France. 

 The following method of destroying the larva of this insect, which is con- 

 oealed under the bark of the Vine during the winter, may possibly prove 

 to be of value in connection with the destruction of other insect pests 

 met with in this country. 



After pruning, and while the buds are yet dormant, the entire plant 

 [a covered with a dome-shaped vessel made of zinc or galvanised iron. 

 Crushed sulphur contained in a cup is ignited and placed under the dome, 

 the latter being well pressed into the ground to prevent leakage of the 

 produced by the burning sulphur. Half an ounce of sulphur is the 

 amount required to use with a dome three feet high and two feet diameter. 

 The cover should be removed after the sulphur has been burning for ten 

 minutes. Times to avoid in carrying out the above measures are when 

 the temperature is below zero, or immediately after rain. — G. M. 



Vines, Large-leaved (Garden, No. 1636, p. 209; 28/3/03).— Apart 

 from the different members of the genus Vitis that are grown solely for 

 the sake of their fruits, there are numerous others remarkable for their 

 handsome leafage, combined in some cases at least with edible berries. 

 K' arded solely from an ornamental standpoint, their merits are by no means 

 sufficiently recognised, for all are beautiful, and may with advantage be 

 grown in different ways. The large-leaved forms are seen to a very great 

 advantage in clothing an arch or pergola, or in rambling over neighbour- 

 ing trees, while nearly all the species form delightful wall plants, and 

 failing these positions each plant may be fastened to a stake, and spurred 

 back annually, so as to consist of gracefully disposed bushes, which are 

 very attractive throughout the summer, and doubly so in the autumn, 

 w hen the foliage of many of them becomes very richly coloured. — E. T. C. 



Vintage treated by Diffusion (Dep. Agr. Victoria, Bull. n. 2).— 

 A translation of Pierre Andrieu's scientific and practical treatise on wine- 

 making by an improved method of abstracting it, with tables of cost and 

 illustrations of machinery. — C. H. H. 



Violas. By D. B. Crane (Gard. Mag. n. 2577, p. 192 ; 21/3/03).— 

 A selected list of the finest Violas, with a description of each, together 

 with cultural notes.— W. G. 



Wall Garden Making-. By P. W. Meyer (Garden, No. 1635, 

 j». 198; 21 8 08).— The writer here deals with retaining- walls : that is, 

 walla meanl to keep up a high bank of soil, or to support a terrace.
