and sand. If the mixture is coarse, pass it through 

 a quarter-inch screen. Coarse pieces of manure may be 

 broken by rubbing them on the screen. 



Over the hole in the bottom of the flowerpot place 

 a piece of broken pot or crockery, with the hollow side 

 down ; then put in at least an inch of broken stone or 

 pebbles, for drainage. On this place a layer of two 



inches of well- 

 rotted barnyard 

 manure, which 

 should be well 

 broken. Then fill 

 soil into the pot 

 so that the bulbs 

 are within one 

 inch of the top 

 after a half-inch 

 layer of sand is 

 put under them. 

 Press down the 

 soil and sand. Place the bulbs in the form of a triangle 

 and press soil around them, leaving the tops barely cov- 

 ered. With a garden sprinkler water the pot thoroughly 

 and set it aside for roots to form. Any place in the 

 schoolroom or in a storeroom will answer the purpose. 

 Callas need not be in sunlight until after growth really 

 begins. Give them very little water during the root- 

 forming period, but gradually increase the amount as 

 the buds appear.
