The frame shown in the drawing, was placed against a wall of a new construction, and which has existed for more than twenty-five years. The wall is formed of a framework of oak, forming squares, in which are set On edge two courses thick of blue paying tiles, nine inches square, so as to break joint. This wall is six and a half feet high, and is covered by a board, x, which serves for a coping, and is supported, from sash to sash, by pieces of wood,y. In the coping boards are fixed hooks which hook into two eyes on each sash. The sashes rest upon oak posts, z, fixed in the ground to the depth of three feet three inches. Each post supports the ends of two sashes, which rest partly on the one and partly on the other, as at w. The sashes, S, are made of pine, and are framed and glazed in the ordinary way. The intervals between the posts are closed up, in severe frosts, by straw mats, t, t, t, which can be removed at pleasure. They are kept from blowing in or out by being tied to laths nailed to the posts.

This is so easily moved, that the whole of it, though fifty-eight feet four inches in length, can be removed by two men in eight minutes, and again replaced in twelve minutes. When the movable part of the structure has been taken down, there only remain the posts, the use of which no one would suspect. Besides effecting its principal object - the protection of fruit-trees, such as the peach, apricot, and vine, etc. - the structure serves, at the same time, for the production of early vegetable crops, for which purpose a border three and a half feet wide is available.

The expense of the entire structure was, at Brussels, 7l 0s. 9d. or about 2s. 5d (or, say sixty cents) per foot run. It is composed of the following items: -

The straw mats might be decidedly objectionable in a cold climate; but they may readily be replaced with glazed sasbes.

Here we were about to be content in having offered a plan of constructing a grape or orchard house for sixty cents a running foot! when another Gardeners' Chronicle brought us the confirming fact, to strengthen an old crotchet of our own, that there is no need of expensive houses to produce premium fruit. The Chronicle says: -

"Wonders will never cease. All the great grape growers were beaten the other day by an interloper. Seldom have practical men received a more heavy fall. Great rules were violated; the wisdom of our forefathers was thrust aside like a piece of useless lumber; and. maxims sanctioned by age, wisdom, and the most resolute routine, disappeared like sparkles of Captain Boxer's fireworks. About a hundred exhibitors of grapes grown in vineries in all parts of the country, produced the evidence of their skill, at the last exhibition in the Regent's Park, and, melancholy to relate, were beaten by fruit from a glass shed in a London nursery garden. It is incredible, though-true. The large .silver gilt, medal, the highest offered for grapes, was awarded to Mr.-----------Glendinning; of the Chiswick Nursery - for three dishes of grapes. Our pen shrinks from recording the event.

"The business of a nurseryman is to grow vines for sale, not grapes for exhibition. If he grows grapes at all, it is only for the purpose of ascertaining that the vines from which he propagates are correctly named. With this end in view, the fortunate winner in the instance before us built a glass shed, or lean-to, with a border and walk at the back, and a tan-pit in front, hot water being added for the necessary heat. This back border is two feet wide; the walk, paved with flat tiles, is two feet more, and beyond this nothing is provided for the, vines to grow in. As to the composition of the border, it appeared to us to consist of little more than the common garden soil of the nursery ground, and we understand that it is nothing else. Along this back border are planted the following vines, in the order in which they follow, and about four feet apart: 1. Black Hamburgh. 2. Muscat of Alexandria. 3. Grizzly Frontignan. 4. White Frontignan. 5. Black Prince. 6. Gannon Hall Muscat. 7. White Tokay. 8. Charlesworth Tokay. 9. Barnes'Muscat. 10. Mill Hill Hamburgh. 11. Reeve's Muscadine. 12. Black Frontignan. 13. Welbeck's Tripoli. 14. A sort undetermined. 15. Black Barbarossa. 161 Royal Muscadine. This, we should say, is as pleasant a party of vines, with different constitutions, as could be readily assembled.

* In our money, about $35.

"They were planted in the narrow back border just described, in June, 1854. A single rod of each was led up the back wall and down the rafters; and laterals from these,rods bore beneath the glass the fruit in question. Fires were, we understand, commenced last March.

"We do not pretend to explain the history of the success of the glass shed. Excellent bunches were still hanging from its roof when we. inspected it, and we have no doubt that the prize fruit was justly placed at the head of all others. Nor do we care to know why nothing' better should have appeared in rivalry. Great parties, past, present, or anticipated, may have caused it What we value the fact for is, that it should teach the amateur the possibility, of also growing in his own small lean-to, grapes fit to take their place by the side of the first in the country. The case is parallel to that of the strawberries lately mentioned".

That will do for the present; we shall see, ere long, who of our countrymen will win the prize of a fortune by growing grapes in cheap structures. It can and will be done.
