ent directions at the same time, the movements of the locusts in the 

 different currents corresponded therewith. 



At one point, where the day was cloudy, none were seen on the wing. 

 At several points a note is made of the fact that the local brood arose 

 and joined the passing swarm. Where the hours are noted, they show 

 the flight to have been during the middle part of the day, or at least 

 between 9 a. m. and 4 p. m. 



Although, as will hereafter be seen, there are exceptions to what here 

 appear to be general rules, yet the rules hold good to a very large extent 

 throughout the entire record, except as to the general direction of the 

 flight, which, as will be seen on the 20th, was southward. 



The first flight of the season, of which we have any notice, was at 

 Bastrop, Tex., on the 19th of April ,^3 to the north. The first in Indian 

 Territory, of which there is any record, was at Camp Supply, May 23, 

 to the northwest; but as the accounts from this Territory are very 

 meager, it is not at all likely that we have received notice of the first 

 observed. The first noted in Kansas was in Trego County, May 17, to 

 the northwest. The first in Nebraska was at Amazon, Franklin County, 

 May 15, to the north. The first in Minnesota, of which any reliable ac- 

 count has been given, was at Raymond, Stearns County, June 5, to the 

 southeast. The first in Dakota was at Medary, Brookings County, June 

 9, moving southeast. 



A BRIEF SUMMARY OF THE FLIGHTS EAST OF THE ROCKY MOUNTAINS 



IN 1877, BY STATES. 



Texas. — The first flight reported was observed, as heretofore stated, at 

 Bastrop on the 19th of April, moving northward. This was followed by 

 another, on the 25th of the same month. A somewhat general and very 

 heavy flight occurred on the 1st of May, notices of which were received 

 from Calvert, Salado, New Braunfels, Dallas, and Austin. This move- 

 ment, which is supposed to have carried off most of the locusts hatched 

 during the spring in this State, was also to the north. A few slight 

 swarms were observed after this up to the 10th of May, but the great 

 body of the insects undoubtedly left about the first of the month. In 

 the latter part ot August swarms began to return southward j immense 

 numbers were observed at this time passing over Eobertson County; 

 others were seen at Bexar, in the latter part of September (28-30), 

 and others at Bastrop, as late as October. 



Missouri. — The locusts which hatched in Jasper and adjoining counties 

 in the southwestern part of the State departed toward the north and 

 northwest during the latter part of May and first of June. Those in the 

 extreme northwest section left in the latter part of June and first few 



^^ Since this was written, additional notes have been received from Texas, through the Signal Service Bu- 

 reau, which may show an earlier date for the first flight. As these are to be found in Appendix No. 3, the 

 reader can easily make the correction, %f necessary.
