sliding shutters, to open and close at pleasure. But in the case of the 

 house being against a wall, where such cannot be made, a false light or 

 weather boarding, twelve or fifteen inches long, should be inserted three 

 inches above the shding sash, that, in unfavourable weather, by not 

 entirely drawing the sash up close, a current of air may pass out, with- 

 out running the risk of admitting rain or chilling drafts. Now, 

 supposing a bright sunny day in February or March, with a frosty air, 

 when, in fact, the interior temperature demands a free ventilation, the 

 Vines maybe aerated dovNm to a nicety without danger, and by graduating 

 the front and back ventilators a gentle current may be allowed during 

 dull weather, and by night, increasing it, of course, as circumstances 

 dictate during the day. I have not said anything about glass. After 

 trying almost every description I prefer the best qualities of " horti- 

 cultural sheet." The squares should not be less than nine inches in 

 width, nor more than twenty-four inches long. 



But I think I hear some of your readers say " Why thus particular? 

 We knew all about this before." Some no doubt do, and to my 

 own knowledge a great many do not. My object is to enable a 

 carpenter and his employer to work the thing out ; the latter will know 

 better the principles involved by the above simple account of details, 

 and the carpenter will see what is wanted. I have only one more 

 word of advice to offer, — let everything be plain and simple ; orna- 

 ments, fancy mouldings, and the like are well enough, but sooner lay 

 out a larger sum in procuring suitable materials wherein to grow the 

 Vines than bestow it on useless ornaments. Inferior Grapes are a 

 poor apology for elegant houses ; while neither yourself nor friends will 

 deem it prudent to criticise your plain and simple structure, if the Vines 

 are producing large finely coloured bunches to reward your attention to 

 their wants.

HOLLYHOCK EXHIBITION. 



A VERY extensive exhibition of this beautiful flower took place at the 

 Surrey Zoological Gardens on the 2 2d ult., when the principal growers 

 of this noble plant competed for the very liberal prizes offered on the 

 occasion ; the productions filled one large tent, the spikes occupying one 

 side, and the cut blooms the other. 



The flowers generally were in first-rate condition. We were 

 also pleased to see several new exhibitors contending for the honours 

 of the day. A new plan was introduced for awarding the prizes, 

 namely, the whole of the exhibitors in the nurserymen's class 

 judged the amateurs' productions, and vice versa. It answered 

 exceedingly well ; the decisions gave universal satisfaction. The 

 seedlings were judged rather too hurriedly. There is seldom 

 time to do justice to new productions at these great meetings, 

 hence the reason the National has been so well supported ; there 

 being nothing besides to interfere, the merits of the seedlings are
