WILLESDEN CANVAS. 



Tliis canvas, like the paper of the same name, 

 possesses great tensile strength, is watertight anil 

 durable. It may be put to the same uses as the 

 Willesden Paper, which see. 



WILLESDEN PAPER. 



This is a special kind of paper, of considerable 

 toughness, and so treated that it is quite water- 

 tight. Several qualities are obtainable. The 

 ' stout brown " is made in rolls about 4i' wide ; 

 it may be turned to good account for protective 

 purposes. Handy screens may be made with it, 

 and, if not subjected to such violence as to tear 

 them, these screens will last for a long time. The 

 lighter samples of paper are sometimes used to pack 

 plants in, especially where they have to travel long 

 distances. Waterproof labels have likewise been 

 inadi) from this paper, but, although they have 

 given satisfaction, they are not often seen. 



WILLOW 0- SALI.X). 



WILLOW SAWFLIES. 



Of all the plants liable to the attacks of Sawflies 

 few are more plagued than the Willows. Thus, of 

 British insects upwards of thirty species of Nematus 

 and twenty species belonging to various other 

 genera feed upon species of Salix, and this does 

 not take into account plants upon the Continent. 

 The mischief may be brought about in one of 

 several ways. Some of the larvas simply eat the 

 leaves, others net as leaf miners, and others cause 

 the formation of galls. Nematus gallicola is the 

 most common of the gall makers, and it is to be

seen on Salix alba, Lapponum, nigricans, and phyli- 

 cifolia, to mention only a few. The so-called Bean 

 Galls are very plentiful. The Pea Galls are chiefly 

 the work of Nematus Pedunculi. As a rule the 

 health of the affected trees does not suffer unless 

 the galls are very numerous, and in that case there 

 is nothing for it but excision of the affected 

 branches. Where there are many of the larvas 

 the trees may be shaken to dislodge them, and the 

 caterpillars may then be swept up and burned, or 

 left to the tender mercies of domestic fowls. 

 Hand-picking may be practised for small trees ; it 

 is out of the question for large ones. Applications 

 of soot, lime, and gas lime to the soil beneath the 

 trees, although not sufficient to get rid of the pests 

 entirely, are yet helpful. 



WILLUGHBEIA (jsyn. ANCYLOCLADUS). 



Stove climbing shrubs (ord. Apocynacese), few of 

 which are in cultivation. Propagation, by cuttings 

 of nearly ripened shoots. Soil, fibrous peat and 

 loam in equal parts, with sand. 



Principal Species : 



edulis, 50', Jy., cl., pale pk., Ivs. 4" to 7" long, 

 fruits edible, as large as a Lemon. 



WINDOW BOXES. 



As with the plants that are grown in windows, 

 inside the room, so with those that are accommo- 

 dated in boxes outside on the sills much depends 

 upon whether the window be a sunny or a shaded 

 one. There is the difference, however, that the 

 occupants of the window boxes are not, as a rule, 

 permanently established in them. Still, if any- 

 thing like lasting effects are desired, only Ferns and 

 green foliage plants should be attempted in shaded 

 windows. If flowering plants are employed they 

 will need to be frequently renewed during the 

 season, with the single exception of the showy 

 shrubby Calceolarias, which do well in shade. 



With regard to the boxes themselves, the most 

 expensive ones are made of stone, more or less 

 elaborately carved, or of china tiles of various 

 patterns. Handsome as these are, it cannot be 

 urged that they are more suitable for the plants 

 than the less expensive but very effective rustic 

 boxes now coming so much into fashion. On the 

 whole, the most satisfactory window boxes are 

 made of wood, and faced with sheets of virgin 

 cork. If made of stout stuff inch boards answer 

 well they will last for several years without 

 repairs. Then a little overhauling annually will 

 keep them in service for several years more. This, 

 of course, applies to boxes that are only allowed to 

 remain out during the summer months that is, 

 from the end of May to the end of September. 

 The life of a box that has to remain exposed to the 

 weather all through the year will of necessity be 

 rather shorter. 



One of two systems may be adopted for filling the 

 box. The plants may be planted out in it, or they 

 may be grown in pots and stood in the boxes when 

 they are in condition. This latter method has the
