round one of the wires which are to form the trellis. The 

 wires should be cut about twelve inches longer than the 

 house to enable the ends to be taken through the central 

 eye and round the wheel in each radisseur, connected 

 to the tubing at the other end of the house by a couple 

 of rounds of the same sized wire, and then tightened with 

 the key to the desired degree of tightness. This done, 

 insert a series of small screw-eyes at twenty inches or 

 twenty-four inches apart, as the case may be, in each 

 rafter immediately above each line of wire, the screw- 

 eyes in each successive rafter being placed angle-wise to 

 those in the preceding one, so that the weight of crop 

 may be distributed equally over the whole trellis and 

 roof of the vinery when the latter is connected with the 

 individual screw-eyes by means of short lengths of wire 

 of the same gauge with hooks formed at right angles at 

 each end. These are to be closed in with a pair of pincers 

 when attached to the wires and screw-eyes, thereby com- 

 pleting a most efficient " hinge "-trellis, which, in many 

 ways, is preferable to the usual stiffly fixed ones. 



In the case of a span-roof vinery, I need hardly say 

 that the trellis described above should be fixed under 

 both roofs in the manner indicated, the top wire being 

 fixed immediately under the apex at the proper distance 

 from the roof glass. The top ends of both sets of 

 tubing should be flattened out a little, and then bolted 

 together through the central upright division bar between 

 lintel and ridge, the bolt being secured on the outside 

 by a nut, and a plate, quarter inch by one inch, and 

 sufficiently long to extend a couple of inches over lintel 

 and end of ridge, having been first placed over the bolt 

 between the nut and woodwork. This plate, being 

 provided with four counter-sunk screw-holes to admit 

 of its being screwed to ridge and lintel, will afford 

 sufficient support to the tubing to resist the strain 

 necessarily involved in tightening the top two or three
