ETHER FORCING WITHOUT GREENHOUSE 223 



the windows face south and east and west. 

 The light is diffused, and there are no 

 draughts. At night the temperature would 

 often go down to 35 degrees or 40 

 degrees. On a few very cold nights 

 we huddled our patients about the 

 radiator, with a screen around them 

 to keep off the cold air which might 

 come up the stairway. In the daytime the 

 temperature averaged about 65 degrees, 

 sometimes climbing up to 70 degrees. 



"When the plants were beginning to bloom 

 they were watered every four or five days 

 with weak manure water. There is a 

 great difference in the thirst of the various 

 plants. Water them when the soil on top 

 gets dry, not before, though there is a great 

 temptation so to do when the plant in the 

 next crock needs a drink. The deutzias 

 were only watered about once a week, but 

 the lilacs and azaleas needed water every 

 day. The plants that were not dosed did 

 not take as much water, for they were not 

 growing as fast.

 could have started early enough, it would 

 have been possible to get the same results.
