70 How TO Grow Cut Flowers. 



frame of wood, use four by four oak or some other firm 

 wood, join one end of the horizontal bar to the shorter 

 upright by means of a bolt passing through both, and 

 thus form a flexible joint. 



Let the longer upright extend as far as it will be de- 

 sirable to raise the wire frame. The bar to which the 

 wires are attached should extend beyond this upright 

 sufficiently — about eight inches — to prevent its slip- 

 ping inside when raised to its top. Fasten this bar at 

 the height desired by a bolt passing through both it and 

 the standard, so that when the frame is raised the 

 bolt can be drawn, and the same bolt again used in 

 another set of holes to keep it in place. It is needless 

 to add that the frames at both ends should be alike 

 and raised simultaneously. 



There are two objections to a wood frame. While it 

 is the cheapest, it looks clumsy, and projecting over the 

 walk, as a movable one must, is apt to be in the way 

 when one is thoughtlessly passing. 



In order to construct a movable frame of gas pipe, the 

 bar to which the wires are attached should be two-inch, 

 but the uprights may be of one and a half inch if de- 

 sired. For making the flexible joint, use an ell, or 

 a close nip and a tee. See Fig 22. 



Let the tee (a) be rimmed out so that the bar (b) will 

 pass through it, and drill a hole for a pin (c), also drill 

 two sets of holes through the bar for the reception of 

 the pin (c), these should be at right angles to each
