only infested spot to be in the center of a small currant patch, having 

 an area of perhaps one-fonrthof an acre. Mr. Wooding had grown his 

 own plants from cuttings for twelve years, and had purchased no cur- 

 rant stock from nurseries. Only three or four bushes were infested, 

 and how the scale got there remains a mystery. 



In suggesting a treatment against the scale we have usually advised 

 the destruction of the worst infested trees, and recommended that 

 others be sprayed while dormant with a solution of whale oil soap — 2 

 pounds of soap in 1 gallon of water. If considered best to spray trees 

 in foliage, 1 pound of soap to 5 gallons of water has been advised. On the 

 1st of last March several seriously infested Japan plum trees in New 

 Haven were sprayed with kerosene. Two mouths later no living scales 

 could be found. The kerosene was applied by means of a " Success" 

 bucket pump, through a Vermorel nozzle, and the spraying done on a 

 bright day, with plenty of air stirring. Where the kerosene was applied 

 with care, little or no injury resulted. One tree literally covered with 

 scales was drenched with kerosene: nearly all the branches were killed 

 back about halfway to the trunk. 



At the station uninfested trees of apple, pear, peach, plum, cherry, 

 and quince were sprayed with kerosene February 28. The only injury 

 that resulted was the killing of a few fruit buds. 



During the past year the writer has been called upon to inspect four 

 different nurseries. In two of them no <• indications of the presence'' 

 of J., perniciosus were found, and the owners were provided with certifi- 

 cates to that effect. Each of the other two nurseries contained a few 

 small trees that were scale infested. 



Counecticut fu-ws no law requiring the inspection of nursery stock, 

 but these inspections were made at the request of the owners. Several 

 cases have been noted where infested trees were purported to have 

 been purchased from local dealers whose stock had been examined and 

 was apparently free from scale at the time of the inspection. The loca- 

 tion of these trees being such as to preclude the probability of their 

 having become infested after leaving the nursery leads me to believe 

 that the San Jose scale has been distributed very extensively in Con- 

 necticut upon nursery stock, and that nearly every nursery in the State 

 has at some time contained infested stock which the owners have 

 unwittingly sold to their customers.
