ROSES UNDER GLASS. 119 



The plants should be placed about sixteen or 

 eighteen inches apart, each way, and should 

 be in position in June or July. When well 

 established and growing freely, give them a 

 mulching of good rotten manure mixed with 

 bone-dust; one shovel bone-dust to twenty 

 of manure is a good proportion. The amount 

 of water to be given will vary with the 

 weather; during clear and hot days they 

 should have a vigorous spraying, given by a 

 syringe or from the hose, twice a day. When 

 it is cloudy or cool they may need but a slight 

 sprinkling once a day. The soil should 

 never be allowed to become dry so as to show 

 dust, or to be saturated with water ; either 

 extreme is dangerous to the health of the 

 plants. From the time of planting out, say 

 the last of June, until the middle of Septem- 

 ber, or until the nights become chilly, all the 

 ventilators should be constantly left wide 

 open ; when cool weather begins they must 

 be closed at night, but air should always be 

 given from the ridge during the day, unless 

 the weather be adverse. It should be the 

 endeavor to keep the temperature fifty-five 

 degrees at night, and sixty-five to eighty de- 

 grees during the da) r . If these instructions 

 are carefully heeded, there will be an abun- 

 dant supply of fine roses all through the sea-
