8 BULLETIN NO. 4, DIVISION OF ENTOMOLOGY. 
Mr. Branner’s report is preliminary to a more extended one, but gives 
a definite idea of what work was accomplished during the Brazilian trip, 
and, with the statement of his instructions, will indicate the objects of 
the trip and the important bearing of the information on the work of 
the Division. 
Mr. Voyle, in his report, gives the results of experiments by which he 
has determined the amount of cold which Scale-insects can bear, thus 
settling a point which has long been in dispute among orange-growers.
