ORANGE CULTURE IN CALIFORNIA. 7 



strained off the water and dissolved in it an ounce of sul- 

 phate of iron. With a hand-brush he applied the solution to 

 the stem and larger limbs, and with a syringe thoroughly 

 sprinkled the leaves and branches. In a week not a living in- 

 sect could be found on the tree, and at the time of writing it 

 was as thrifty as any he had. 



C. V. Riley, of Washington, D. C, advises syringing the tree 

 with a mixture of about one part of kerosene to twenty or thirty 

 of water, kept well mixed. He says care must be used not to 

 get too much oil, as it may injure the tree if used too copiously. 



Some growers use a mixture of blue vitriol and soapsuds. 



Win. H. Ashmead, of Jacksonville, Florida, writes that, from 

 specimens received at different times, there would seem to be 

 three broods, if not more, during the year. The first brood 

 probably hatches in May, the second from the last of July to 

 the second week in August, and the third from the last of Sep- 

 tember to the first week in October.
