210 HOUSE PLANTS 



not injure the plants. Don't use a gas 

 heater under any circumstances, for gas is 

 bound to escape through the connections, 

 and nothing is so injurious to plants as is 

 gas. For the very small greenhouse there 

 are small forms of hot water boilers which 

 are economical of fuel, and give a large 

 amount of heat. 



Knife. A good budding knife, costing about 

 ;^i.25, should be kept on hand for making 

 cuttings, etc., and used for this purpose only. 

 Keep it with a keen edge, to make clean cuts. 



Pans. When growing bulbs use pans 

 which are made especially for this purpose. 

 They are not as deep as pots of the same 

 diameter would be. For instance, a pot 

 eight inches in diameter would be eight 

 inches deep; but a pan of that same diameter 

 would be only about half as deep. This 

 is plenty deep enough for bulbs, as it fur- 

 nishes plenty of root room and they are more 

 attractive, not showing such an expanse of 

 red clay. These pans are also very useful 

 for starting seeds. 



Pots. They must be good. There are 

 a great many pots on the market which are 

 so thin that they are very easily broken.
