The second passage occurs in Jer. viii. 7: "Yea, the stork in the heaven knoweth her appointed times; and the turtle, and the crane [sis], and the swallow observe the time of their coming; but my people know not the judgment of the Lord." With regard to this passage, the Jewish Bible renders the word sis as Swallow, though with the mark of doubt.

Allusion is here made to the migratory habits of the Swift. There is, perhaps, no bird more conspicuous in this respect; for whereas the other migratory birds seem to straggle, as it were, into the country, the Swifts arrive almost simultaneously, so that on one day not a Swift will be seen, and on the next the air is full of their dark, glancing forms.

Like the Swallow, the Swift haunts the neighbourhood of man, and loves to build its simple nest in the roofs of houses. Almost any hole will do for a Swift to build in, provided that it be tolerably deep; for the bird loves darkness for its nest, though it is essentially in its habits a bird of light.

Perhaps the word "build" is scarcely the right one, inasmuch as the nest is even more simple than that of the sand-martin. This latter bird does indeed arrange with some regularity the feathers which compose its nest, as may be seen by a beautiful specimen obtained by Mr. Gould; whereas the Swift merely places together a quantity of hay, straw, hair, feathers, and similar materials, all of which are probably obtained from the ruins of a sparrow's nest which had occupied the hole before the Swift took possession of it.

Several species of Swift inhabit Palestine. The common Swift (Cypselus apus), with which we are so familiar, is very plentiful, and so is the ALPINE SWIFT (Cypselus melba), a bird which is rare in England, though it occasionally visits our shores. It is much larger than the common Swift, and is brown above and white below, instead of being dusky black, like the common species.

"

The most characteristic species is, however, the GALILEAN SWIFT (Cypselus affinis). Of this kind, Mr. Tristram remarks that it is very like the house-martin in general appearance and size. It resides all the year in the Jordan valley, where alone it is found, living in large communities, and has a pleasing note, a gentle and melodious wail, very different from the harsh scream of the other swifts. Its nests are very peculiar, being

composed generally of straw and feathers, agglutinated together by the bird's saliva, like those of the edible swallow of Eastern Asia. They are without any lining, attached to the under side of an overhanging rock. It also sometimes takes possession of the nest of the rufus swallow for its purposes. The Galilean swift has a wide range, being found in India and Abyssinia."

It is possible that this may be the Sis mentioned by Hezekiah, its soft wailing cry being used as the metaphor to express his own complaining.

As might be expected, the Talmudical writers have much to say on this bird.

For example, the offering which a leper made at the cleansing of his infirmity might be the Tzippor-deror, the rather quaint reason being that it was a bird with sharp scratching claws, and was therefore very appropriately offered in connexion with a disease of the skin. Here we have rather a complication of terms, the word tzippor being used, as we shall presently see, to signify the sparrow in particular, or any little bird in general. The particular species, therefore, which is signified by the combination of the two words tzippor-deror is rather obscure, and the Talmudists themselves are rather uncertain about it. The interpretation of this compound word seems, however, to have been a difficulty, and the various renderings which have been suggested seem at last to have varied between the wild pigeon, or rock-dove, and the Swallow. An account of the various arguments is given by Lewysohn in his "Zoologie des Talmuds," page 206, and may be briefly epitomized, as follows, in favour of the Swallow, or, as we shall soon see, the Swift.

The reader may perhaps be acquainted with the legend respecting the death of Titus, how a gnat made its way through his nostril into his brain, and there grew and kept him in constant torture until he died, when, according to some writers, it had reached the size of a Tzippor-deror, and weighed two selaim. Others enlarged upon this story, and said that it grew as large as a wild pigeon, and weighed two pounds. Now, as twenty-five selaim are equal to one pound, it follows that the Tzippor-deror must have been very much less than the wild pigeon, and that therefore the two birds could not have been identical.

Another reason for believing the Tzippor-deror to be a much. smaller bird than the pigeon is found in a curious rule respecting the eating of certain meats. The Jews were forbidden to eat date-shells with the heathen, unless they were cooked in a vessel with an opening so small that a Tzippor-deror could not have been introduced into the pot. The reason of this curious proviso was, that if any unclean flesh, such as that of the swine, or of any animal which had been offered to idols, had been cooked in that vessel, even the date-shells would become unclean. But, if the mouth of the pot were too small for a Tzippor-deror to be passed through it, such a vessel could not have been used in cooking meat, and might therefore be assumed to be clean. Here, then, we have another proof of the small size of the bird. With regard to this argument, I find myself perplexed as to the " date-shells." Dates have no shells, and need no cooking, while the stones are too hard and woody to be rendered edible by any amount of cooking. Still, the word employed by Lewysohn is "dattelschalen."

The leper's offering was not laid on the altar, but was submitted to a peculiar manipulation on the part of the priest. Among other points of ritual, the blood had to be mixed with a certain quantity of water, which it barely discoloured, staining it of a very pale red. As the amount of water was the fourth part of a "log," and is defined to be equal to the contents of six hen's eggs, it was evident that the bird whose blood would only discolour so small a volume of water must be a little one.

After giving all these details, the learned writer sums up his arguments by saying that he believes the Tzippor-deror to be the White Swallow, which is small, and has claws so sharp that by means of them it can cling to the wall. Now this action is one of the characteristics of the Swifts, who often cling to walls for a time, and then resume their flight. They do so in preference to sitting on the ground after the fashion of the Swallow, because the great length of the wings causes the Swift to find some little difficulty in rising from a level surface. After weighing all the various arguments that have been urged on the subject, we may conclude that the Tzippor-deror was the White, or Alpine Swift, which has been already described on page 389.

THE HOOPOE, OR LAPWING OF SCRIPTURE

The "Dukiphath" of Scripture-Various interpretations of the word—The Hoopoe-Its beauty and ill reputation-The unpleasant odour of its nestFood of the Hoopoe-Its beautiful nest, and remarkable gestures-A curious legend of Solomon and the Hoopoe.

IN the two parallel chapters, Lev. xi. and Deut. xiv., there occurs the name of a bird which is translated in the Authorized Version, Lapwing: "And the stork, the heron after her kind, the lapwing, and the bat."

The Hebrew word is dukiphath, and various interpretations have been proposed for it, some taking it to be the common domestic fowl, others the cock-of-the-woods, or capercailzie, while others have preferred to translate it as Hoopoe. The Jewish Bible retains the word lapwing, but adds the mark of doubt. Commentators are, however, agreed that of all these interpretations, that which renders the word as HOOPOE (Upupa epops) is the best.

There would be no particular object in the prohibition of such a bird as the lapwing, or any of its kin, while there would be very good reasons for the same injunction with regard to the Hoopoe.

In spite of the beauty of the bird, it has always had rather an ill reputation, and, whether in Europe or Asia, its presence seems to be regarded by the ignorant with a kind of superstitious aversion. This universal distaste for the Hoopoe is probably occasioned by an exceedingly pungent and disagreeable odour which fills the nest of the bird, and which infects for a considerable time the hand which is employed to take the eggs.

The nest is, moreover, well calculated for retaining any unpleasant smell, being generally made in the hollow of a tree, and having therefore but little of that thorough ventilation which is found in nearly all nests which are built on boughs and sprays.

The odour in question proceeds from a substance secreted from the tail-glands of the Hoopoe, and is not due, as was long supposed, to the food which was brought to the nest.

There was good reason for supposing that this evil odour was caused by the food, inasmuch as the Hoopoe is in the habit of raking about in very unsavoury places in search of insects. But

it does not therefore follow that the insects which it finds are possessed of an evil smell. On the contrary, some of the worstsmelling insects-notably the lace-wing fly and many of the flower-haunting hemiptera-are invariably found upon the leaves of trees and the petals of flowers; while others which, like many of the scarab beetles, haunt the most repulsive substances, are in themselves bright, and clean, and sweet.
