able supplies were secured at Raton and transported from the nearest 
Milroad station by wagon, except for a period in June, when heavy rains 
ished out railroad tracks and telephone lines (this in a dry country), 
aus cutting us entirely off from the outer world - or would you say 
fmaner worla"? We were always well supplied with food and other neces— 
ities. A near-by "watering hole" with its friendly well and windmill 
Upplied us, as well as our friends, the cattle, with abundant drinking 
ater. 
E* For locomotion we many times used our own motive power but for 
Dnvenience and for longer trips were supplied with two cow ponies and 
wo Indian motorcycles, the latter with tandem attachment for carrying 
Ouble. We were thus able to cover a considerable area and, being 
at not only in the midst of the outbreak but probably near where 
had its origin, we were able to "live with our work," literally as 
ell as figuratively. 
_ For an insectary we tried several arrangements. We had to have 
hade. First muslin was used, but because of the heavy winds wnich 
Pring up nearly every afternoon from the snow-capped mountains to tne 
fest and southwest of us, this was shown to be impracticable. A tent 
oo not be used because of the already mentioned midday rise in tem- 
rature. so finally a tent fly was secured, only instead of beirg 
ver @ tent it was itself resting upon a ridge pole and with the lower 
ges tied high up on the supporting guy posts so that there was abun- 
nt circulation of air from all sides. This was found to be a very 
latistactory arrangement and was of course a protection from the rain 
iS well as from the sun. Convenient shelves were then constructed and 
placed beneath this, thus making room for our small cages, trays, etc. 
fhis kind of protection proved to be so well adapted to the work that 
[t seems that it could be used to advantage in other sections or at 
bther laboratories where only a temporary shade is wanted. 
: Our Work was divided along five lines: First, the life history 
ind habits of the range caterpillar. This had already been admirably 
Married througn one season and parts of others by Mr. C. N. Ainslie but 
fas now considered from a broader viewpoint and over a larger section 
f the country, with better equipment for carrying through the work. 
pscond was the scouting work to ascertain the present distribution of 
mae Species and the corresponding relation between its distribution and 
Mtural barriers. We find a considerable relation here, the mountains 
bo the west apparently checking it entirely, while the extremely dry 
rea, in central New Mexico is almost as complete a barrier, The path 
f dispersion from the present area is open to the eastward. 
| The third division of our work was the mechanical methods of con- 
rol, Under this work came such-things as brush dragging, rolling, 
d burning the infested area. Of course it at once occurs to the 
reader that these methods are almost prohibitive because of the rela- 
bively small value of the land per acre and the greatness of area covered 
md managed by one man. However, it was hoped that some success migat 
be héd in this line, as often severe outbreaks occurred in spots or 
restricted areas especially on the edge of newly infested territory. 
fhe results of such work were not very encouraging, however, and more 
experimenting is needed along this line.
