I erect a light wooden frame over the place where the plants are to be wintered, fixing it against a wall having a north aspect. This frame is four feet high at back, and two feet high in front. On the bottom, where the pots stand, I lay slates, in order to prevent the ingress of worms; I then place my pots in rows, beginning at the back of the frame, and fill up with sand to within about an inch of the rim of the pot, - the sand keeps the roots in an equable condition, protecting them against intense frosts. For covering, I use calico done over with oil mixed with a small portion of white lead, - the latter gives substance to the cloth, and prevents rain from penetrating it. On all favourable opportunities I throw off the cover, in order to admit all the air and light that I can; but when rain, snow, black frosts, or boisterous winds occur, I keep it on.

In open weather 1 examine the plants every night with a lighted candle, and remove any slugs that may be feeding on them; by attending to this, and to what some may call trifles, great losses are often prevented: the careful florist who attends to the minutiae of his calling, though he may only have fifty pairs of Carnations, will frequently beat the careless cultivator of 500. Out of near a hundred plants, I only lost some seven or eight; and the plants I wintered as above were far stronger, less drawn, and healthier, than some which I got in spring, and which had been wintered under glass.

We are precluded by want of space from offering our ideas upon the situation and construction of these useful and agreeable additions to our gardens and grounds; but we hope to do so before long; and in the mean time we shall be glad to receive suggestions from any of our readers who may feel inclined to favour us with their views on the subject, which may be embodied in an article calculated, we believe, to be useful; for we have often observed great mistakes committed in these erections, which might be made so highly ornamental, and which are so well adapted for the display of many of our most beautiful climbing plants.
