LOCAL FLIGHTS IN 1877. 165 



For these reasons the movements of the locusts east of the mount- 

 ains, in 1877, must be largely included in the category of '^ local flights," 

 in the broad sense, that is to say, flights whose limits are within the 

 visited area or temporary breeding-grounds. 



LOCAL FLIGHTS. 



As before stated, the past season has been a very favorable one for 

 studying "local flights" or limited migrations, and the means adopted 

 by the Comaiission for collecting data upon this point have resulted in 

 accumulating a very large amount of material. 



We give, in Appendix 13, in an abbreviated form, the answers on 

 this point received from our numerous correspondents, in order that all 

 who desire to do so may have an opportunity of studying this subject 

 for themselves, and thus be able to test the correctness of our conclu- 

 sions. 



In order to give an idea of the amount of material collected in refer- 

 ence to these flights, we give here a summary or rather brief notes of 

 the replies received to our circular No. 1, relating to two days, July 3 

 and 20, remarking only that the flights from the more Southern States 

 had almost entirely ceased at this season. 



In these records the direction of the wind wherever mentioned is to 

 be understood as that from which it was blowing j and where flights 

 are mentioned without giving the direction, they are to be understood as 

 going with the wind. The language of the correspondent has been re- 

 tained as nearly as possible.
