It is probable, that when these northern Countries are buried in Snow, and their Rivers are frozen up, these Birds take their Flight hither, and such like Places, where they have access to Water, _&c._ But as to Cuckows and Swallows, as intimated above, ’tis generally allow’d that they sleep in Winter, having, as ’tis said, been found in hollow Trees and Caverns. Nor is this at all unlikely; tho’ on the other hand, I can see no Absurdity in supposing that these should go upon a Summer, as the other do upon a Winter Pilgrimage; that these pursue a lesser Heat, as well as the others fly from a greater Cold. Yea, _Vegetables_ are said to _sleep in Winter_, and to be awake and lively in Summer: During the Months of their Rest, a quantity of Oil is laid up in them for their Defence against the Cold, and in proportion to the Degrees of it, which they are to sustain; whence it is, that the Trees of the northern Climates so much abound with Oil. On the other hand, there are _Reptiles_ and _Insects_ that have Sense enough to lay up Winter-Store in Summer, as the _Bee_, _Wasp_, _Field-Mouse_, _&c._ a Property foreign to the ancient House of Serpents. In Summer, the _Bees_ labor hard for Winter Provision: As soon as the Air grows mild and warm, they are out betimes, and gather their Harvest from the Simples of the Fields, which they suck into their Bodies, and upon their Return to the Hive they disgorge it, as Pigeons do their Food wherewith they feed their Young. When the Bees have fill’d their Storehouse with the Delicacies of Nature, they lock the Doors, which they seal up with delicate white Wax, to prevent the Emanation of the Honey, which is a vegetable Juice: The Combs in which their Treasure is lodg’d, are geometrically nice, and exceed the most exquisite Art of Man. The Ants also in this respect, are remarkable for Penetration and Foresight. In _America_ are Ants which raise Hillocks four or five Foot high, and have such a way of cementing the Earth about them, that ’tis as firm as Lime and Stone, which protects them against the _Ant-Bears_, or Pismire-eaters; _i. e._ a kind of Creatures as big as Dogs, that feed on these Insects. One observes, that the _Spaniards_ left _Jamaica_, and went to _Cuba_, for this Reason among others, because their Childrens Eyes were eaten by these Ants, when left by themselves in the Cradle[10]. Footnote 10: Sir _Hans Sloan_’s _Introduction to his Voyage_, p. 68. Ceylon in the _East-Indies_ produces several sorts of remarkable Ants, particularly a large red kind, which make their Nests on the Boughs of great Trees, with Leaves wrapt together in Clusters, in which they lay their Eggs: And another sort call’d _Vacos_, whose Hinder-part is white, and the Head red; these swarm over the Land and devour every thing, but Stone and Iron: They creep on House-walls, and always build an Arch over themselves; on these their Poultry live chiefly; some of them bite desperately.
