ICE LETTUCE 337 



APPENDIX VII 



ICE LETTUCE 



THIS lettuce is described in the ' Transactions of the Horticultural Society,' 

 vol. vi. (1826), p. 575, as follows : 



" Seeds of this lettuce were brought from the United States, under the above 

 name, by Mr. David Douglas, in 1823, and it was raised the following year. It 

 belongs to the division of Silesian or Batavian Lettuces, and must not be con- 

 founded with the Ice Lettuce of Scotland, which is our White Cos Lettuce. The 

 leaves are of a light shining green, blistered on the surface, very undulated, and 

 slightly jagged round the edges ; they grow nearly erect, being eight inches long, 

 and five or six broad. The outer spread a little at the top, but grow very close 

 at the heart. It blanches without tying up, and becomes very white, crisp, and 

 tender. It comes into use with the White Silesian, from which it differs, as it also 

 does from any other of its class, in being much more curled, having a lucid spark- 

 ling surface, whence probably its name, and not turning in so much at the heart. 

 It lasts as long in crop as the White Silesian."
