Certain it is that the swallows neither come hither for warm weather nor retire from cold; the thing is of quite another nature. They, like the shoals of fish in the sea, pursue their prey; they are a voracious creature, they feed flying; their food is found in the air, viz., the insects, of which in our summer evenings, in damp and moist places, the air is full. They come hither in the summer because our air is fuller of fogs and damps than in other countries, and for that reason feeds great quantities of insects. If the air be hot and dry the gnats die of themselves, and even the swallows will be found famished for want, and fall down dead out of the air, their food being taken from them. In like manner, when cold weather comes in the insects all die, and then of necessity the swallows quit us, and follow their food wherever they go. This they do in the manner I have mentioned above, for sometimes they are seen to go off in vast flights like a cloud. And sometimes again, when the wind grows fair, they go away a few and a few as they come, not staying at all upon the coast. _Note_.—This passing and re-passing of the swallows is observed nowhere so much, that I have heard of, or in but few other places, except on this eastern coast, namely, from above Harwich to the east point of Norfolk, called Winterton Ness, North, which is all right against Holland. We know nothing of them any farther north, the passage of the sea being, as I suppose, too broad from Flamborough Head and the shore of Holderness in Yorkshire, etc. I find very little remarkable on this side of Suffolk, but what is on the sea-shore as above. The inland country is that which they properly call High Suffolk, and is full of rich feeding grounds and large farms, mostly employed in dairies for making the Suffolk butter and cheese, of which I have spoken already. Among these rich grounds stand some market towns, though not of very considerable note; such as Framlingham, where was once a royal castle, to which Queen Mary retired when the Northumberland faction, in behalf of the Lady Jane, endeavoured to supplant her. And it was this part of Suffolk where the Gospellers, as they were then called, preferred their loyalty to their religion, and complimented the Popish line at expense of their share of the Reformation. But they paid dear for it, and their successors have learned better politics since.
