ose rows of
shallow, irregularly shaped hollows. Their number is enormous--in the
males as many as thirty-nine thousand, and, in the female, thirty-five
thousand on each antenna. As some of the scent-laden air reaches the
surface of these pits, it causes the nerves of smell to be roused, and
so guides the beetle to its mate, or to its food, according to the
nature of the smell. These pits are so tiny that they cannot be shown on
the antennal leaves of the cockchafer shown in fig. 5, but they are
there. On fig. 6 a highly magnified section of one of these 'leaves' of
the antenna is shown: 'P' is the pit, 'N' is the nerve, and 'S. C.' the
sense-bulb of the nerve in which it terminates--the point at which the
smell is perceived.

It has been proved that insects which have lost their antennae have no
sense of smell.

AFLOAT ON THE DOGGER BANK.

A Story of Adventure on the North Sea and in China.

(_Continued from page 279._)

Fourteen days after leaving Liverpool the _Twilight_ arrived at Port
Said, and Fred, Charlie, and Ping Wang at once went ashore. The Pages
thoroughly enjoyed their first glimpse of the East, for Ping Wang,
knowing the place, took care that they should see everything worth
seeing. After sitting for a time in a big _cafe_ which was crowded with
men of almost every European nation, they wandered through the shop
district, and out into the Arab portion of the town.

After they had looked at the sights for some little time, Ping Wang
suggested that they should have a donkey ride. They had noticed the
large, handsome donkeys soon after they landed, but as the passengers
from a big P. & O. vessel had come ashore just before they arrived, all
the animals were engaged. But when they returned to the busy part of the
town they found three donkeys on hire, and the donkey 'boys,' two of
whom were elderly men, at once shouted out the names of their animals.

A Port Said donkey sometimes has its name changed three or four times in
a year, in consequence of its proprietor's desire that it shall always
bear one which is just then popular with Englishmen. You may ride on
