In many parts of the country, about October fifteenth the crows begin to flock back and forth to and from their winter roosts. In some years it is the twelfth, or again the seventeenth, but the constancy of the mean date is remarkable. Many of our winter visitants have already slipped into our fields and woods and taken the places of some of the earlier southern migrants; but the daily passing of the birds which delay their journey until fairly pinched by the lack of food at the first frosts extends well into November. It is not until the foliage on the trees and bushes becomes threadbare and the last migrants have flown, that our northern visitors begin to take a prominent place in our avifauna.

Season of mists and mellow fruitfulness! Close bosom friend of the maturing sun;
Where are the songs of spring? Ay, where are they? Think not of them, thou hast thy music too,— While barred clouds bloom the soft-dying day, And touch the stubble-plains with rosy hue; Then in a wailful choir the small gnats mourn Among the river-sallows, borne aloft Or sinking as the light wind lives or dies; And full-grown lambs loud bleat from hilly bourn; Hedge-crickets sing, and now with treble soft The red-breast whistles from a garden-croft, And gathering swallows twitter in the skies.
John Keats.

A WOODCHUCK AND A GREBE

No fact comes to mind which is not more impressed upon us by the valuable aid of comparisons, and Nature is ever offering antitheses. At this season we are generally given a brief glimpse—the last for the year—of two creatures, one a mammal, the other a bird, which are as unlike in their activities as any two living creatures could well be.

What a type of lazy contentment is the woodchuck, as throughout the hot summer days he lies on his warm earthen hillock at the entrance of his burrow. His fat body seems almost to flow down the slope, and when he waddles around for a nibble of clover it is with such an effort that we feel sure he would prefer a comfortable slow starvation, were it not for the unpleasant feelings involved in such a proceeding.

As far as I know there are but two things which, can rouse a woodchuck to strenuous activity; when a dog is in pursuit he can make his stumpy feet fairly twinkle as he flies for his burrow, and when a fox or a man is digging him out, he can literally worm his way through the ground, frequently escaping by means of his wonderful digging power. But when September or October days bring the first chill, he gives one last yawn upon the world and stows himself away at the farthest end of his tunnel, there to sleep away the winter. Little more does he know of the snows and blizzards than the bird which has flown to the tropics. Even storing up fruits or roots is too great an effort for the indolent woodchuck, and in his hibernation stupor he draws only upon the fat which his lethargic summer life has accumulated within his skin.

As we might expect from a liver of such a slothful life, the family traits of the woodchuck are far from admirable and there is said to be little affection shown by the mother woodchuck toward her young. The poor little fellows are pushed out of the burrow and driven away to shift for themselves as soon as possible. Many of them must come to grief from hawks and foxes. Closely related to the squirrels, these large marmots (for they are first cousins to the prairie dogs) are as unlike them in activity as they are in choice of a haunt.

What a contrast to all this is the trim feathered form which we may see on the mill pond some clear morning. Alert and wary, the grebe paddles slowly along, watchful of every movement. If we approach too closely, it may settle little by little, like a submarine opening its water compartments, until nothing is visible except the head with its sharp beak. Another step and the bird has vanished, swallowed up by the lake, and the chances are a hundred to one against our discovering the motionless neck and the tiny eye which rises again among the water weeds.
