foliage will develop at a rapid rate and provide good 

 supplies of tender shoots. Pick these off and let the 

 parent stalk continue reproduction. Add water to the 

 bottles as occasion demands. Another and perhaps 

 better plan is to sow seeds during March or September 

 in pots of ordinary soil, standing them to half their 

 height in bowls of water. While the seeds are germi- 

 nating protect them by means of a covering sheet of glass. 

 When plants are an inch high, permanently immerse 

 the pots in the rain-water tub, in an aquarium, or large 

 bowl of water. Gather carefully and remove as little of 

 the main growth as possible. 



Where a supply of water cannot be conveniently 

 obtained, it will be well to sow Upland Cress, seeds of 

 which may be purchased freely. This variety is difficult 

 to distinguish from watercress, serves the same purpose, 

 and is easy to propagate. 



Sorrel. This useful vegetable may well be grown 

 by those who have ample room. When included in 

 salads it imparts a pleasing sharp, almost acrid taste, 

 and when boiled as spinach is very acceptable. Sow 

 in mid-spring or early summer and thin out drastically. 

 Pick the leaves when large enough ; the roots may 

 remain in the ground for a number of years. Sorrel 

 thrives in moist but not heavy soils.
