at first, a bright vermilion red in color. As they grow this 
color fades into a rusty brown. When mature, the mite re- 
sembles a very small spider and is just large enough to be 
plainly seen by one who has fairly good eye-sight. 
As the result of the attacks of this mite the foliage of 
the tree becomes bleached and sickly in appearance. Aside 
from the pear it attacks badly the cherry, apple and plum 
and perhaps a few other trees. 
Remedies — Those who use the lime, sulphur and salt 
wash in the vicinity of Grand Junction, Colo., assure me 
that it completely rids their trees of Brown Mite. 
In my own experiments I have found whale-oil soap in 
the proportion of one pound to 4 gallons of water, or kero- 
sene emulsion diluted so that the kerosene will be one- 
eighth of the mixture, applied before the eggs hatch, to de- 
stroy the latter completely, none whatever hatching where 
thousands were treated, d'he same applications in one-half 
the foregoing strengths will kill the mites after they hatch. 
The best time to make the treatment is before the eggs 
hatch. 
THE PEAR-TREE SLUG. {Eviovam }>u veraEi Peck.) 
This insect attracts attention as slimy, olive-green slugs 
upon the leaves, which they kill by eating off the soft part 
and leaving the veins. When abundant, they entirely de- 
stroy the foliage, leaving the leaves brown and dry as if 
killed by fire. There are two broods, one appearing in June 
and one in August.
