the time of its antler growth to the
universal rule which obtains in the great arctogeal realm, where deer
of many species abound and where the fossil forms show that they have
long existed. The marsh-deer, which has diverged much further from the
northern type than this bush deer (its horns show a likeness to those
of a blacktail), often keeps its antlers until June or July, although
it begins to grow them again in August; however, too much stress must
not be laid on this fact, inasmuch as the wapiti and the cow caribou
both keep their antlers until spring. The specialization of the marsh-
deer, by the way, is further shown in its hoofs, which, thanks to its
semi-aquatic mode of life, have grown long, like those of such African
swamp antelopes as the lechwe and situtunga.

Miller, when we presented the monkeys to him, told us that the females
both of these monkeys and of the howlers themselves took care of the
young, the males not assisting them, and moreover that when the young
one was a male he had always found the mother keeping by herself, away
from the old males. On the other hand, among the marmosets he found
the fathers taking as much care of the young as the mothers; if the
mother had twins, the father would usually carry one, and sometimes
both, around with him.

After we had been out four hours our camaradas got lost; three several
times they travelled round in a complete circle; and we had to set
them right with the compass. About noon the rain, which had been
falling almost without interruption for forty-eight hours, let up, and
in an hour or two the sun came out. We went back to the river, and
found our rowboat. In it the hounds--a motley and rather worthless
lot--and the rest of the party were ferried across to the opposite
bank, while Colonel Rondon and I stayed in the boat, on the chance
that a tapir might be roused and take to the river. However, no tapir
was found; Kermit killed a collared peccary, and I shot a capybara
representing a color-phase the naturalists wished.

Next morning, January 1, 1914, we were up at five and had a good New
Year's Day breakfast of hardtack, ham, sardines, and coffee before
setting out on an all day's hunt on foot. I much feared that the pack
was almost or quite worthless for jaguars, but there were two or three
of the great spotted cats in the neighborhood and it seemed worth
while to make a try for them anyhow. After an hour or two we found
the fresh tracks of two,
