the spring of 1903. In orchards the less pruning done this spring the 

 less will be the damage the trees are likely to suffer, as this opera- 

 tion tends to concentrate the punctures by leaving little new growth. 

 Likewise, wherever convenient, budding and grafting, which cause 

 favorable places for the deposition of eggs, should be avoided. 



AN EXCEPTION. 



In the Connecticut valley there is a limited region where Brood XI 

 (Marlatt's notation) will appear during the spring of lOOo. This 

 locality, which is the only one in the United States where swarms 

 of cicadas will appear that year, includes only Hartford County in

Connecticut and Bristol, Franklin, and Hampshire counties in 

 Massachusetts. This brood has become scattered and is rapidly 

 dying out. In 1880 it attracted but little attention and in 1903 will 

 be still less in evidence. However, in places where the insects are 

 known to have appeared in numbers in 1886 in the counties mentioned 

 above it will be unwise to transplant trees extensively in the spring 

 of 1903. In all other portions of the United States the year 1903 

 will be, as far as the periodical cicada is concerned, very favorable 

 for tree planting, because it will be followed by a year in which, as 

 far as is definitely known, there will be a total absence of swarms 

 of this insect.
