We hear complaints of the scarcity of Bluebirds from year to year. I have watched, at intervals since early April, the nest of a single pair of Bluebirds in an old apple tree. On April 29th there were four young birds in the nest. On May 4th they had flown; an addition was made to the dwelling, and one egg of a second brood was deposited. On May 31st the nest again held four young Bluebirds. June 15th saw this second quartette leave the apple tree for the outer world, and thinking surely that the little mother had done, I appropriated the nest; but on June 25th I found a second nest built, and one white egg, promising a third brood. From the four laid this time, either a collector or a Bluejay deducted one, and on July 14th the rest were just out of the shell. This instance of the industry of one pair of Bluebirds proves that their scarcity is no fault of theirs. I may add that the gentle mother suffered my frequent visits and my meddling with her nursery affairs without any show of anger or excitement, uttering only soft murmurs, which indicated a certain anxiety. May not the eleven young Bluebirds mean a hundred next season, and is not the possessor of the missing egg guilty of a dozen small lives?" We have observed that the enthusiasm of boys for collecting eggs is frequently inspired by licensed "collectors," who are known in a community to possess many rare and valuable specimens. Too many nests are despoiled for so-called scientific purposes, and a limit should be set to the number of eggs that may be taken by any one for either private or public institutions. Let us influence the boys to "love the wood-rose, and leave it on its stalk." [Illustration: EGGS] 1. Spotted Sandpiper. 2. Bartramian Sandpiper. 3. Marbled Godwit. 4. King Rail. 5. American Coot. 6.

Mrs. Wren, in a very contented frame of mind, sat upon her nest, waiting with an ever growing appetite for that delicious spider or nice fat canker worm which her mate had promised to fetch her from the orchard. "How happy I am," she mused, "and how thankful I ought to be for so loving a mate and such a dear, little cozy home. Why, keeping house and raising a family is just no trouble at all. Indeed--" but here Mrs. Wren's thoughts were broken in upon by the arrival of Mrs. John, who announced, as she perched upon the rim of the tin-pot and looked disdainfully around, that she had but a very few minutes to stay.
