phere will rob them of no water. Hence they maintain their 

 freshness. The only difference between plants in a '-Ward's 

 case," and flowers in the little apparatus just described, is this — 

 that the former is intended for plants to g-row in for a consider- 

 able space of time, while the latter is merely for their preservation 

 for a few days ; and that the air which surrounds the flowers is 

 always charged with the same quantity of vapour, but will vary 

 with the circumstances, and at the will of him who has the 

 management of it. We recommend those who love to see plenty 

 of fresh flowers in their sitting-rooms in dry weather, to procure 

 it. The experiment can be tried by inserting a tumbler over a 

 rosebud in a saucer of water. — Gardeners^ Chronidc.
