Some forms of these are found in water, as in streams, ponds, and
ditches, while other forms are found on land, where they hide under
stones and sticks. They are commonly mistaken for lizards, which they
closely resemble in shape; but the two animals may be distinguished by
the fact that the surface of the body of a salamander is smooth, while
that of a lizard is covered with scales.
The small red or copper-coloured newts are the most common in Ontario
and are frequently found on roads after heavy rains. The tiger
salamanders are larger than the red newts and are marked with orange and
black spots, hence the name "tiger". Many people believe this species
to be especially venomous, while in reality it is quite harmless and,
like the other salamanders, is useful for destroying insects and small
snails, which form the greater part of its food.
_To the teacher._--The superstition of the salamander's power to
extinguish a fire into which it is thrown still exists. The early life
of the salamander is spent in water, the young form being very much like
a tadpole. The salamanders are close relatives of the frogs and toads
and may be kept in a jar or vivarium in wet moss or grass. The pupils
should learn to recognize the animals and should be instructed as to
their habits.
SPIDERS
~Problems in observation.~--In how many places can you find spiders' webs?
How many forms of spiders' webs can you find? Are the many webs that are
found on the meadow grass in the dewy mornings the homes of spiders? If
so, describe where the spiders live. (At the bottom of tunnels that run
into the ground.)
What uses do spiders make of their webs? (Trapping prey, supporting egg
cases, protection, and means of moving, as in the case of cobweb
spiders.)
Drop a fly upon a spider's web and observe the action of the spider.
Search under the webs of spiders in attics and sheds and learn, from the
skeletons found there, what the spider feeds upon. It will be found that
flies, beetles, and other spiders are killed by this monster.
Watch a spider spinning its web and find out what parts of the body are
used in this work. It will be seen that the threads are produced from
little tubes at the rear end of the animal and are placed and fastened
by means of the feet.
Examine, by the aid of a hand lens, the feet and head of the spider.
Note the "brushes and combs" on the former. Note, on the latter, the
four, six, or eight eyes (the number and arrangement vary), and the
short poison claws at the front of the head. How are the poison claws
adapted for seizing and piercing? Note the sharp hooks at the lower
ends.
BIRD STUDIES
Continue the lessons in bird identification and in bird types, using the
methods outlined for these studies in Form III. (See pp. 217-24.)
