PROPS are the supports required by 

 plants to sustain them in a desired posi- 

 tion. They must vary in height and 

 strength accordantly with the plant to 

 which they are applied, and should always 

 be as slight as is consistent with effi- 

 ciency. Nothing looks worse than a dis- 

 proportioned prop; indeed, it should be 

 concealed as much as possible. The props 

 for peas should be of the branches of 

 the hazel, or of frames and strings, which 

 we prefer ; for runner kidney beans, rods 

 of ash. For flowers, stout iron wire, 

 painted brown or dark green, is to be 

 preferred. Whenever wooden props are 

 used, the end thrust into the ground 

 should be previously charred ; if this 

 precaution be taken, and when, no longer 

 required, they are stored in a dry shed, 

 they will last for several seasons. Props 

 should be placed on the south sides of 

 the plants, as they incline in that direc- 

 j tion, as being most light.
