TRE 



Espalier Trellis made of cast iron 

 rods, are much more durable, and 

 neater, than that made of wood. 



Trellis for Climbers. These have 

 been greatly improved, or rather they 

 have been created within these few 

 years, for ten years ago we had nothing 

 but stakes and rods. 



Their forms are now various and 

 elegant ; but we shall here only explain 

 the manner in which the wire-trellis 

 for climbing plants, is attached to the 

 pots. It will be seen that a strong 





wire ring is carried round the pot, a 

 little above its bottom. To this a suffi- 

 cient number of upright wires are 

 attached all round. These upright wires 

 are pressed down upon the surface of 

 the pot, till they reach the lim, over 

 which they are firmly bent till they 

 reach the highest point of the rim, or 

 are even bent a little within it. At 

 this point they are secured by a second 

 ring of stout wire, adjusted as in the 

 drawing, which having been done, the 

 uprights are directed upwards, and 

 fashioned into the pattern required. 

 By these means a sort of collar is 

 formed upon the rim of the pot, which 

 prevents the trellis from slipping down- 

 wards, while at the same time, the 

 lowest ring of wire keeps it from 

 swinging and swaying backwards and 

 forwards. 



Umbrella Trellis is a form excellently 

 adapted for Wisteria sinciisis, and other 

 climbers or shrubs having long racemes 

 of flowers. (See cut.) 



Hothouse Trellis for training vines 

 near the glass, is usually made of thin 

 rods of deal or of iron, placed about a 

 foot apart, and fastened to the frame- 

 work of the building. Mr. Long, Beau- 

 fort-place, Chelsea, has invented a 



moveable wire trellis, by which the 

 vines may be lowered from the roof, or 



placed at any angle, without injuring 

 the vines. This is an excellent mode 

 of removing them from the influence 

 of extreme exterior heat or cold. A 

 still further improvement would be to 

 have the vertical rods moveable round 

 the rod horizontally fixed to the rafter 

 or roof, for then the whole trellis might 

 be raised to an angle with, or even 

 close to the glass, whenever sun to the 

 vine upon the trellis, or shade to the 

 plants within the house, was desirable. 



TREMBLING AMERICAN TREE. Po'- 

 pulus tre'mida. 



TRENCHING is one of the readiest 

 modes in the gardener's power for 

 renovating his soil. The process is 

 thus conducted : From the end of the 

 piece of ground where it is intended to 

 begin, take out a trench two spades 

 deep, and twenty inches wide, and 

 wheel the earth to the opposite end to 

 fill up and finish the last ridge. Mea- 

 sure off the width of another trench, 

 then stretch the line and mark it out 

 with the spade. Proceed in this way 

 until the whole of the ridges are out- 

 lined, after which begin at one end and 

 fill up the bottom of the first trench 

 with the surface or ' top spit ' of the 

 second one; then take the bottom 

 ' spit ' of the latter, and throw it in 

 such a way over the other as to form 

 an elevated sharp-pointed ridge. By 

 this means a portion of fresh soil is 

 annually brought on the surface in the
