larger they are consistent with easy lifting the better. A 
breadth one foot on the side will be useful, but fifteen inches 
adds to the usefulness, while adding very little to the cost of 
the frame. If frames of light timber, fifteen inches on the 
side, are put together at an angle of about fifty degrees, there 
will be space within for sheltering a plant twelve inches high, 
and if made in twelve feet lengths, a man can move them 
without difficulty. They should be closed at the ends, of 
course, for they are to be protectors in every sense of the 
word.
