late forcing, as wel! as the durability thereof, whether the roof be of 
metal or wood ; and practical men can Kcnerally furcsec ami provide 
for ultimate success in such buildinsjs, either on a large or small scale, 
but mechanical patentees are more likely to produce novelty to the eye, 
than useful economical hot-houses for use in a fruit garden. 
Where large ornamental conservatories are wanted, the Baileys of 
London, or the Birmingham manufacturers, would certainly produce a 
more light and elegant effect, than the dark, heavy, barnlike buildings 
made by the ornamental architects of former times. 
Hot-house roofs, wholly of metal, are of too recent a date to say any- 
thing positive on the number of years they will last ; but wood roofs 
and sashes have been in use long enough to show that we ought to be 
satisfied with them on the score of durability. I now give the age and 
condition of some hot-houses of long standing. 
A pine-stove, 105 feet long, all the roof of deal wood, has been in con- 
stant use 57 years, it has had some repairs lately, and there does not 
appear the least doubt but it will last 57 years longer. This house 
has a flattish pitch, the angle of inclination being only 26 degrees. 
A vinery and peach-house, upwards of 200 feet long, the rafters of 
oak and sashes of deal, has been in constant use 1 10 years; they have 
had a new front-wall-plate, and other repairs, and no person can say 
when it will be worn out ; the sashes have not a rotten tenon nor bro- 
ken bar in them. This roof has a sharper pitch, the angle being 45 
degrees. 
Other cases of durability in wood hot-house roofs of intermediate age 
and angles of altitude are in abundance, but the above two cases are 
sufficient to show what we may expect from cheap wood roofs — the 
durability of dear metal ones remains to be proved.

Gentlemen, 
If you think the following account of a remarkable large espa- 
lier Apple-tree, worth inserting in your new Magazine, it is entirely at 
your service. The sort is well known in this neighbourhood by the 
name of the Doveridge J^onsuch, and from what I know of it, and the in- 
formation I have been able to obtain of it from others. 1 find it has been
