The Psalmist notices the partiality of this bird for the temple of worship, the sanctuary of God: “Yea, the sparrow hath found an house, and the swallow a nest for herself, where she may lay her young, even thine altars, O Lord of hosts, my King and my God.” Psalm lxxxiv. 3. Hezekiah, king of Judah, wrote of himself, “Like a crane or a swallow, so did I chatter.” Is. xxxviii. 14. In these casual notices we at least trace out that the habits, migration, and song of the swallow, were known to the inspired writers; a circumstance of no little value, since a false assertion that the facts of natural history are not correctly stated in the Bible, has long been among the weak engines used by the infidel against the validity of that book, “which maketh wise unto salvation.”
The Sand Martin, or Bank Swallow, is a most curious bird of this family. It is the least of the tribe, and the first to arrive, appearing a week or two before the swallow, and often while the weather is severe. Its flight is vacillating, but it is equally fond of skimming over the surface of the water. This bird, unlike its race, mines deep holes in sand or chalk cliffs, to the depth of two feet, or even more, at the extremity of which it constructs a loose nest of fine grass and feathers, artificially put together, in which it rears its brood.
The sand martin is of a social disposition; hence flocks of them unite to colonize a favorite locality, such as a precipitous bank or rock, which they crowd with their burrows. Professor Pallas says, that on the high banks of the Irtish, their nests are in some places so numerous, that, when disturbed, the inmates come out in vast flocks and fill the air like flies; and, according to Wilson, they swarm in immense multitudes along the banks of the Ohio and Kentucky.
What, it may be asked, are the instruments by which this little creature is able to bore into the solid rock, and excavate such a chamber? Its beak is its only instrument. This is a sharp little awl, peculiarly hard, and tapering suddenly to a point from a broad base; with this tool the bird proceeds to work, picking away from the centre to the circumference of the aperture, which is nearly circular; thus it works round and round as it proceeds, the gallery being more or less curved in its course, and having a narrow funnel-shaped termination. The author of “The Architecture of Birds” informs us that he has watched one of these swallows “cling with its sharp claws to the face of a sandbank, and peg in its bill, as a miner would do his pickaxe, till it had loosened a considerable portion of the sand, and then tumbled it down amongst the rubbish below.”
The Human Frame likened to a House.
Man’s body’s like a house: his greater bones
Are the main timbers; and the lesser ones
Are smaller joists; his limbs are laths daubed o’er,
Plastered with flesh and blood; his mouth’s the door;
His throat’s the narrow entry; and his heart
