if the Tropaeolum makes little growth the first season. 

 If it appear the second year, and is well attended to 

 in the way of water supply, it will grow more vigor- 

 ously, although one can hardly be sure of having 

 established it until it has reached a height of six or 

 seven feet in the second season. It must also have 

 twine or rough twigs to cling to. T. tuberosum is 

 only half-hardy and the tubers ought to be treated 

 like potatoes, planted out in April, and lifted when 

 the foliage becomes yellow, and stored in a frost-proof 

 place in winter.
