TRELLISES FOR VINES 21 



pathway about three and a half or four feet from the 

 back wall. A span, twenty feet wide with fifteen feet 

 rafters, should have two four-inch flows on each side 

 suspended by substantial hooks, attached to and gripping 

 wall plates, and one return on either side of the central 

 pathway. 



TRELLISES FOR VINES 



Trellises for training vines should be fixed longi- 

 tudinally not less than fifteen inches from the glass at 

 intervals of from ten to twelve inches. A cheap, simple 

 and most efficient trellis may be made as follows : 

 Fix a piece of one and a quarter inch gas tubing corre- 

 sponding with the length of rafter to mullion and 

 door-post at, say, fifteen inches from the roof glass, 

 with bolts a quarter of an inch thick, tightening these 

 up on the outside by means of nuts, one small plate 

 of iron being placed between each of these and the 

 wood to prevent the nuts cutting into the latter when 

 screwed home, as well as to afford additional strength 

 and durability to the work when completed. This 

 done, place three vertical bars of one inch by quarter 

 inch iron at equal distances from the junction of front 

 with end wall-plates to the doorpost, the irons being 

 twisted, crunked about two and a half inches at top, and 

 flattened out a little at each end to admit of them being 

 secured to wall-plate and end rafter with large wooden 

 screws, two screws at each end. The quarter inch edge 

 of irons should rest perpendicularly against the tubings, 

 thereby enabling them to withstand the great strain 

 necessarily incurred in tightening the individual wires, 

 which should consist of No. 14 (galvanised). Having 

 marked the position which each of the wires is to 

 occupy ten to twelve inches apart on the tubings 

 with a piece of chalk, take the end of each wire once 

 round the tubing, and twist it three or four times
