26 REPORT UNITED STATE8 ENTOMOLOGICAL COMMISSION. 
Other plans have been proposed (one or two will be mentioned further 
on under General Remarks), but as most of them are still less feasible and 
show a want of knowledge of the character of the breeding grounds and 
the difficulties to be overcome, it is unnecessary for us to consider them. 
The proposition for the government to burn over the areas of egg deposit* 
after the young are hatched out offers some hope as a means of their 
destruction, but, as we have seen, appears to be impracticable with the 
hinited population in the permanent region. 
Collecting and destroying the eggs and young in the permanent breed- 
ing grounds, which is hereafter noticed, is worthy of careful consideration, 
as it is possible; but the immense expense it will entail has prevented 
us from mentioning it among the practicable remedies. 
We are, therefore, of the opinion that the best plan to be followed is, 
first, to adopt measures to throw an agricultural population into the 
radiating points of the permanent breeding grounds, commencing with 
the portion of Montana designated ; and, if possible, induce the Domin- 
ion Government to unite in this effort so far as relates to the region 
immediately north of the international boundary along the east flank of 
the Rocky Mountain range. 
The plan proposed in our First Report of stationing a corps of observers 
connected with the Signal Service Bureau in the breeding areas of the 
Northwest for the purpose of gathering information in reference to the 
extent of egg deposits and numbers hatching, and to give notice of these 
facts and the departure of swarms, we think not only entirely feasible, 
but important, and one that would be of immense value in locust years 
to the sections the swarms from this region are in the habit of visiting. 
Second. As to the Temporary Region. 
What has been stated in the previous part of this chapter in refer- 
ence to the probable effect of the settlement of the belt in Montana on 
the locust problem in its relation to this region need not be repeated 
here. As the relation of the locust problem to agriculture in the tem- 
porary region has already been discussed in our First Report, and as the 
chief objects we had in view in devoting a chapter to the general sub- 
ject in this report were to consider the feasibility of the plan for de- 
stroying the locusts by burning over the grassy areas of the permanent 
region and to present the scheme herein mentioned, we do not design 
to enter at present into an extended discussion of this second divisio 
of the subject. 
The experience of the farmers of this section in fighting the youn 
locusts, a more thorough knowledge of their history and habits obtaine 
through the work of the commission, the complete fulfillment of the pre 
dictions of the commission that 1877 would close the series of the inv~ 
sion which had continued from 1874, and the conclusive proof of th 
theory advanced by the commission that this pest could not remain per- 
manently in this region, have served to dispel the terror these insects 
once inspired, and should no other remedies than those already known
