They were not noticed as far south as Corsicana, Texas, but were 

 observed to be numerous at Dallas, sixty miles to the north. 



Manitoba. — LitUe or no cultivation was attempted in many parts 

 of Manitoba, owing to the prevalence of locusts in the Spring. Mr. 

 G. M. Dawson, in an interesting pamphlet " on the Locust Invasion of 

 1874 in Manitoba and the Northwestern Territories," just published in 

 Montreal, remarks that " the position of Manitoba, near the north- 

 eastern limit of the range of the locust, is in so far favorable as it is 

 only exposed to invasions from directions included between wett and 

 south; and the prevailing winds being northwesterly and coinciding 

 with the direction of the migration instinct of the insect, carry the 

 greater number of the swarms from their breeding places to the South- 

 western States. The northern situation of the province also tends ta 

 exempt it from a double visitation, first from southern, and then from 

 northern and northwestern broods." He states, however, that the 

 number of the insects borne to Manitoba, is more than sufficient to 

 produce great injury. 



AMOUNT OF DAMAGE DONE IN MISSOURI. 



In making an estimate in figures of the amount of damage done 

 by the locusts, several important considerations must be kept in view. 

 First, it is impossible to arrive at strict accuracy, for we have no 

 such means of collecting facts covering a whole county, as would en- 

 able us to ascertain the exact damage upon each farm or quarter sec- 

 tion. Then, the amount of injury to fruit and gardens, and the per- 

 manent injury co fruit trees, meadows and pastures, can scarcely enter 

 into our calculation. The number of improved acres varies in counties 

 of nearly the same area. Different counties received different meas- 

 ures of harm, owing to the different character of the surface, the rela- 

 tive amount of timber, etc. 



The immediate damage was the loss of labor expended in plant- 

 ing, and the seeding for about two thirds of the crop acreage of the 

 country, to which the destruction of the tame grasses and of fruit may 

 be added. The value of these it is difficult to get at. I have requested 

 a number of correspondents to give an estimate of the probable 

 damage in their county from the young locusts, and I append a few of 

 the answers as samples, from counties which received the greatest in- 

 jury. Many find it impossible to make an estimate, while a few deem 

 that their counties, for one reason and another, were not materially- 

 injured by the locusts. 



The loss to Lafayette county was fully two millions of dollars.— [J. Belt, Napo-
