Mr. Webster called attention to the fact that when a chief has the 

 ropntation of givina^ en-edit to his assistants for the work actnally 

 performed by them, liis publications have a better standing than they 

 otherwise would, because it is known exactly who carried out each 

 jiart of the work. In this way the responsibility for any of tlie results 

 that are published can be definitely placed. Joint pi'blication is all 

 right, provided the chief has actually put the final touches on the work 

 of his subordinates and not simply attached his name to the hitter's 

 work. 



The meeting adjourned in order to hold a joint session with the 

 Society for the Promotion of Agricultural Science, which was called 

 to order in the same room. Mr. Fletcher introduced Professor 

 Osborn, who occupied the chair for the joint session.

REMEDIES FOR THE SAN JOSE SCALE. 



By E. P. Felt, Albany, N. Y. 



Experimental work against this scale insect was begun by us sev- 

 eral years ago, and the following is a brief summary of results: 



Early spring applications of a 20 per cent mechanical crude petro- 

 leum emulsion indicated that it was one of the most effective methods 

 of controlling this pest, and that if the spraying was properly done 

 very little or no injury resulted to the trees. This was true not only 

 of the more resistant pear and apple, but also of the more delicate plum 

 and ijeach. Certain trees have been sprayed by us four years in 

 succession with crude oil, and we are confident that the enlarged 

 lenticels and very rough bark is a result. This does not seem to be 

 a very material injury to the trees, though in one instance the foliage 

 of a pear was deficient in size and abnormally light in color. We 

 proteose to test further the effect of continued applications, and it 

 may be that trees can not stand it in oui* climate. The oil has the 

 advantage of being very easily applied, and its tendency to run 

 around limbs is a distinct advantage. Unreliability of mechan- 

 ical jjumps is a serious objection, though wo believe that even this
