rday in the
railway-station yard, I felt no doubt that it contained Mr. Turton and
Augustus. The driver turned and stooped down towards the off-side
window, as if to speak to them, while the next instant, a head being
thrust out, he pointed in my direction with his whip.

Now what was I to do? It seemed that although they might be able to see
that I was a boy, the distance was too great to enable Mr. Turton to
recognise me, with any certainty, as his runaway pupil. Fortunately, the
lane began to wind to the right a few yards ahead, and taking to my
heels, I was soon out of sight of the occupants of the cab.

A few yards further still, the lane bent again, and more sharply, so,
seizing the opportunity, I climbed over a gate on the left into a large
meadow, which contained a great many sheep and cattle.

INSECT WAYS AND MEANS.

III.--HOW BUTTERFLIES, FLIES, AND SNAILS FEED.

When we come to examine the methods by which the more lowly creatures
take up their food, we cannot but feel astonished at the marvellous
number of contrivances by which this is done. To bring home this fact,
let us compare the methods of feeding of two of our commonest insects
with those adopted by another and very different group of animals--the
Mollusca, taking the common snail as an example.

By the butterflies and moths the food is taken in a liquid form--honey
procured from flowers--by means of a most marvellously complex 'tongue'
or 'proboscis.' This organ, when not in use, is coiled up so as to be
out of harm's way, but when the creature desires to feed it can be
extended with wonderful rapidity. Its length is astonishing: in many
cases, as in some of the hawk-moths, it attains a length of four to five
times that of the body, and in some species it may be as long as ten
inches! The general shape of this tongue you will see in the figure
marked A, which shows what the tongue is like when seen under the
microscope.

[Illustration: Fig. A.--Tongue of Butterfly (greatly magnified).]

Carefully examined by the aid of a microscope, this tongue will be found
to be made up of two separate tubes lying side by side, and, as each
tube is grooved along its inner side, it follows that when the two
separate halves are brought together, a third tube lying between the two
outer ones is formed. So closely do these two halves fit when closed
that t
