where, as summer advances, spiders embroider with silken lace all the grasses, rocks, and old woodwork of the farm. Such busybodies as these may attract little notice ; but no one can overlook or fail to enjoy the lepidoptera. Everywhere you go butterflies dance before your steps, or rise and dip and curvette in the bright air about your head, while at night the moths flock to your lighted windows, equally delicate but less gay of hue, as befits beings whose life is mainly passed in darkness. “Summer,” remarks Scudder, “ with blazing sun and diversified blossoms, brings us the hot-looking coppers, and all that dappled band of fritillaries and angle-wings, blocked in red and black above, and often variegated by odd dashes and spots of burnished silver, or by peacock-eyes beneath. How they crowd about the thistles, spreading thistle-blossoms, or on the many-flowered umbels of the milkweed, and fan themselves with content at their sweet lot.”

But, as has been said, it is the quiet stream or shaded pond which especially attracts the rambler now; and what beauty arises from the dark mud of many a weedy pool! Rosy lilies, the dancing snowflakes of the water-ranunculus, golden buttercups setting off the rich violetpurple of the water-hyacinth, and, alongshore, prince of all the pondside, the scarlet spikes of the cardinal-fower. Here and there over the smooth surface dart and glide the skater-beetles, and over all zigzag innumerable dragon-fies, throwing metallic reflections, blue, green, and bronze, from their burnished armor and gauzy wings.

There are a thousand things to be studied in the cool water, but most conspicuous are the nests of the sunfishes, the commonest example of which is the mottled, orange-finned pumpkin-seed. They are most brilliant of hue and at their best now; and all are near the shore of their pond, depositing their eggs in saucer-shaped nests of sand and pebbles, or guarding them with jealous care.

The black bass do the same ; and one may sometimes find a dozen of their nests side by side, over each of which is poised a vigilant male, steadily fanning away with golden wings the moving sand or falling sediment lest it defile the eggs, and darting out to frighten into flight some predatory or too inquisitive fish or other swimmer which threatens the beloved home. Later, when the fry have hatched, the watchful parents keep them together in their inexperience, guide the flock into sheltered places among the weeds, and guard them as a collie does his sheep against the many wolves of the water.

Equally assiduous and watchful are the ugly little bullheads, whose refuges are holes in the bank into which they drive their young when danger threatens, and place themselves at the door, looking out with staring eyes and menacing barbels like a grim ogre at the gateway of a magic castle. In the same quiet waters the yellow perch are leaving black dots of eggs hanging upon the weeds and submerged sticks in long glutinous strings like silver ribbons. Now, too, many marine fishes are spawning

among the rocks or eel-grass of northern
coasts, and sea-angling is at its best.

Snakes and turtles are hiding their leath-
ery eggs in the warm earth; and—but-a

on in this midsummer world.
