Snakes
Sometimes the rustling is a snake on his way to a sunny spot where he can bask and sleep. Very slender brown speckled snakes, or blind-worms, are quite harmless, and so are the large grass-snakes, which are something like a mackerel in lines and markings. The adder, however, which is yellowish brown in color with brown markings and a "V" on his head, is dangerous and should be avoided.
Ants
On [p. 205] is given the title of a book about bees. Hardly less wonderful are ants, concerning whom there is much curious information in the same work, the reading of which makes it ten times more interesting to watch an ant-hill than it was before. One sometimes has to remember that it is as serious for ants to have their camp stirred up by a walking-stick as it would be for New York if Vesuvius were tossed on top of it.
Swallows and Hawks
In the flight of birds there is nothing to compare for beauty and speed with the swift, or for power and cleverness with the hawk. On moist evenings, when the swifts fly low and level, backward and forward, with a quaint little musical squeak, like a mouse's, they remind one of fish that dart through the water of clear streams under bridges. The hawk, even in a high wind, can remain, by tilting his body at the needed angle, perfectly still in the air, while his steady wide eyes search the ground far below him for mice or little birds. Then, when he sees something, his body suddenly seems to be made of lead and he drops like a stone on his prey. A hawk can climb the sky by leaning with outspread wings against the breeze and cork-screwing up in a beautiful spiral.
Squirrels
The time to see squirrels is September and October, when the beech nuts and hazel nuts are ripe. In the pictures he sits up, with his tail resting on his back, holding nuts in his little forepaws; but one does not often see him like this in real life. He is either scampering over the ground with his tail spread out behind him or chattering among the branches and scrambling from one to another. The squirrel is not seen at his best when he goes nutting. His beautiful swift movements are checked by the thickness of the hazels. In a beech grove he has more liberty to run and leap. Sometimes you will see twenty at once all nibbling the beech nuts on the ground. On hearing you they make for a tree trunk, and, rushing up it for a yard or two, stop suddenly, absolutely still, with fearful eyes, and ears intently and intensely cocked. If you stand equally still the squirrel will stay there, motionless, like a piece of the tree, for a minute or so, and then, in a very bad temper, disappear from view on the other side of the trunk, and probably, though you run round the tree quickly several times and search every branch with your eyes, never come into sight again. It is a good thing to sit under a tree some distance from the beech trees, making as little movement as possible; and by and by you will cease to be considered as anything but a regular part of the landscape and the squirrels may come quite close to you.
