 sirable, say 48"" to 56° F. It is self evident 

 that open-air beds must be protected from 

 drenching rains. 



Inquiries are frequently sent in asking if 

 it is possible to spawn pastures and lawns and 

 thus establish natural cultures to increase the 

 "spontaneous" autumn supply. I have had 

 no permanent success in this kind of work, 

 and the failures were under a variety of con-

 similar version of this natural or field cul-

 be attained under field conditions. The
