THE SMYRNA FIG AT HOME AND ABROAD 47 



This was a new phase in the matter, for all writers on this subject had described 

 only three generations of the insect, but in the salubrious climate of California a 

 fourth generation had developed.

Branch of Roeding's Capri No. 1, showing two winter or Mamme figs (the two nearest the lower 

 side of plate), from which the hibernated Blastophaga are about to issue, and the bunch of spring 

 or Profichi Figs (near the tip of the branch) which are in the receptive stage, that is, ready to re- 

 ceive the Blastophagas issuing from the winter figs. Reduced from an original photograph. 



Not knowing how low a temperature the Mamme or fall crop of figs would stand, 

 it was deemed advisable to protect those remaining on the trees during the winter 

 months, and over three of the trees, those in which this crop was the most abundant, 

 a cloth house was Built, 28 feet wide, 75 feet long and 16 feet high. This covering 

 served its purpose admirably, and on March 5, 1900, when Mr. E. A. Schwarz, the 

 special agent from the Division of Entomology at Washington, arrived, he found 

 fully 400 or more of the Mamme crop, in fine condition, all of which, from their gen- 

 eral appearance, indicated that they contained the insect in the hibernating state. 

 Quite a few figs on the Capri Fig trees, which were not covered, were also found to 

 be in fine shape, although the temperature during the winter on several occasions 

 had been as low as 29 deg. Fahrenheit.
