Plan of Hopperdozer. Urbahns. 
Fig. 8. 
North of Wilkin County, near Crookston, 
Fertile and Beltrami, and also in Otter Tail 
County and elsewhere, practically the same 
conditions existed. In some cases we fur- 
nished oil free to farmers, for use in hop- 
perdozers. There is no law directing the 
entomologist to do this, but he looked upon 
the existing conditions as an emergency, and 
wished to do all he could to assist men en- 
deavoring to raise crops under these trying 
conditions. Perhaps fifty hopperdozers 
were in daily use in one neighborhood in 
Wilkin County. 
Letters complaining of grasshoppers be- 
gan to reach our office early in June, rapidly 
increasing in numbers during that month, 
and continued arriving in large bunches un- 
til late in August and even into September ; 
and this division of the Experiment Station 
was kept busy, both in visiting different 
localities and in correspondence. 
We mentioned above the furnishing of 
free oil to needy farmers who required it 
for hopperdozers (see account below). In 
this connection it should be said that the 
State Entomologist’s fund is not sufficient 
to meet any such demand, and particularly 
would this be the case if we were deluged 
with the pest. It is to be hoped, therefore, 
that some special legislation may be en- 
acted this winter, covering the needs in 
question.
