Packard.] RELATIONS OF INSECTS TO MAN.

horrible persecutions of these blood-thirsty creatures, I took 
refuge one night in the cart, and was congratulating myself 
on having at last secured a place free from their attacks. 
But I was mistaken; I had not been long asleep before I 
was awakened by a disagreeable irritation over my whole 
body, which shortly became intolerable: and notwithstand¬ 
ing the night air was very sharp and the dew heavy 1 , I cast 
off all my clothes and rolled on the icy-cold sand, till the 
blood flowed freely from every pore. Strange as it may 
appear, I found this expedient serviceable. 
“ On another occasion, a bush-tick, but of a still more poi¬ 
sonous species, attached itself to one of my feet; and, 
though a stinging sensation was produced, I never thought 
of examining the part, till one day, when enjoying the unu¬ 
sual luxury of a cold bath, I accidentally discovered the in¬ 
truder deeply buried in the flesh, and it was only with very 
great pain that I succeeded in extracting it, or rather its body, 
for the head remained in the wound. The poisonous effect of 
its bite was so acrimonious as to cause partial lameness for 
the three following months. The bush-tick does not confine 
its attacks to men only, for it attaches itself with even 
greater pertinacity to the inferior animals. Many a poor 
dog have I seen killed by its relentless persecutions; and 
even the sturdy ox has been known to succumb under the 
poisonous influence of these insects.” Sometimes also while 
one bivouacs on the ground, these ticks will enter the ear 
and become exceedingly troublesome. These and other 
insect intruders can be made to leave their retreats by 
pouring a drop of oil into the ear. 
Fig. 67 gives an excellent idea of. the common cattle 
tick of the south when gorged with blood. The lower figure 
represents the tick when younger and after fasting. (The 
upper figure is of the natural size, the lower several times en¬ 
larged.) Fig. 68, adult, and six-legged young. Fig. 69 
shows the mouth parts much enlarged, with the spiny tongue.
