the seedlings, and to keep the weeds very carefully removed 
until at least the middle of July, after which they may sometimes 
-be left to advantage to afford winter protection; but in the case 
of very small seedlings this protection is best given by a light 
mulch, put on in autumn and taken off in spring, and the weeds 
should be kept out. 
If the seeds of Red Cedar, the Thorn, Mountain Ash, and 
other seeds that require a long time to start, are sown in the 
spring, and do not germinate, it is a good plan to cover the bed 
with about an inch or two of hay or leaves, keep out weeds, 
and let this mulch remain until the following spring, when the 
seeds will probably be in condition to grow, and the mulch 
should then be removed.
