The madonna lily should be planted in Au- 

 gust, as it puts out a new growth of foliage in 

 the early autumn. The scarlet Martagon lily 

 makes an early root growth and therefore ought 

 to be in the ground by the middle of October. 

 Aside from these two species, lilies may be 

 planted in the autumn any time before the 

 ground freezes. Not infrequently it is difficult 

 to get imported bulbs in season to do that; in 

 such an event, the ground may be prepared and 

 kept from freezing by means of a heavy tem- 

 porary covering of manure. Then the bulbs 

 can be planted as late as December. A few of 

 the lilies will do well if bulbs carried through 

 the winter in cold storage are planted in April
