90 PRACTICAL FLORICULTURE. 



be opened, and enough heat be supplied from the rooms 

 of the dwelling ; or, better yet, if it were so arranged that 

 a register from the furnace opened into the floor of the 

 greenhouse. But when this supply of artificial heat can- 

 not be obtained, the greenhouse as it is, will be sufficient 

 to protect plants against any frost that is likely to occur 

 in this latitude after April 20th, particularly if light 

 wooden shutters are put over the lower tier of sashes. I 

 have recommended this style of greenhouse to many 

 dealers and retail florists in the different States. Those 

 who are simply dealers in plants, experience great diffi- 

 culty and loss in keeping what they purchase for sale, in 

 stores or dwelling rooms ; for if not sold at once, they 

 quickly get injured. But this cheap and simple style of 

 greenhouse, not only by its appearance advertises their 

 business as dealers in flowers, but it enables them to buy 

 from the wholesale florists at an earlier season. Besides 

 this, they can purchase in March and April, at less than 

 half what the same plants would cost in May, and it gives 

 them time to repot into larger pots. Placing them in the 

 greenhouse, where they have sufficient space to grow, the 

 plants that are bought for $5 per 100 in March, with but 

 little trouble in potting, airing and watering, will freely 

 retail for twenty-five cents each in May. These green- 

 houses are also economical and useful to the amateur who 

 purchases for his flower garden in the spring. Bedding- 

 plants, as they are called, cannot be safely planted out in 

 the Northern States until the middle of May, and if the 

 amateur buys from the florist then, he generally pays 

 quite double the price that he could purchase the same 

 plants for in March or April, for the florist always wants 

 room in his greenhouses, and can better afford to sell a 

 dozen Geraniums in March for seventy-five cents than for 

 $1.50 in May. Besides, the plants if purchased in March, 

 and shifted into larger pots, and allowed plenty of room 

 to grow, would be far better than could be purchased at
