LETTER X.

_August 4th_, 1767.

It has been my misfortune never to have had any neighbours whose studies

have led them towards the pursuit of natural knowledge; so that, for want

of a companion to quicken my industry and sharpen my attention, I have

made but slender progress in a kind of information to which I have been

attached from my childhood.

As to swallows (_hirundines rusticae_) being found in a torpid state

during the winter in the Isle of Wight or any part of this country, I

never heard any such account worth attending to. But a clergyman, of an

inquisitive turn, assures me, that when he was a great boy, some workmen,

in pulling down the battlements of a church tower early in the spring,

found two or three swifts (_hirundines apodes_) among the rubbish, which

were at first appearance dead, but on being carried towards the fire

revived. He told me, that out of his great care to preserve them, he put

them in a paper bag, and hung them by the kitchen fire, where they were

suffocated.

Another intelligent person has informed me, that while he was a schoolboy

at Brighthelmstone, in Sussex, a great fragment of the chalk cliff fell

down one stormy winter on the beach, and that many people found swallows

among the rubbish; but on my questioning him whether he saw any of those

birds himself, to my no small disappointment, he answered me in the

negative; but that others assured him they did.

Young broods of swallows began to appear this year on July 11th, and

young martins (_hirundines urbicae_) were then fledged in their nests.

Both species will breed again once. For I see by my fauna of last year,

that young broods came forth so late as September 18th. Are not these

late hatchings more in favour of hiding than migration? Nay, some young

martins remained in their nests last year so late as September 29th; and

yet they totally disappeared with us by the 5th October.

How strange it is that the swift, which seems to live exactly the same

life with the swallow and house-martin, should leave us before the middle

of August invariably! while the latter stay often till the middle of

October; and once I saw numbers of house-martins on the 7th November.

The martins and red-wing fieldfares were flying in sight together, an

uncommon assemblage of summer and winter birds!

A little yellow bird (it is either a species of the _alauda trivialis_,

or rather perhaps of the _motacilla trochilus_) still continues to make a

sibilous shivering noise in the tops of tall woods. The stoparola of Ray

(for which we have as yet no name in these parts) is called in your

zoology the fly-catcher. There is one circumstance characteristic of

this bird which seems to have escaped observation, and that is, it takes

its stand on the top of some stake or post, from whence it springs forth

on its prey, catching a fly in the air, and hardly ever touching the

ground, but returning still to the same stand for many times together.

I perceive there are more than one species of the _motacilla trochilus_.

Mr. Derham supposes, in "Ray's Philos. Letters," that he has discovered

three. In these there is again an instance of some very common birds

that have as yet no English name.

Mr. Stillingfleet makes a question whether the blackcap (_motacilla

atricapilla_) be a bird of passage or not: I think there is no doubt of

it: for, in April, in the first fine weather, they come trooping, all at

once, into these parts, but are never seen in the winter. They are

delicate songsters.

Numbers of snipes breed every summer in some moory ground on the verge of

this parish. It is very amusing to see the cock bird on wing at that

time, and to hear his piping and humming notes.

I have had no opportunity yet of procuring any of those mice which I

mentioned to you in town. The person that brought me the last says they

are plenty in harvest, at which time I will take care to get more; and

will endeavour to put the matter out of doubt whether it be a nondescript

species or not.

I suspect much there may be two species of water-rats. Ray says, and

Linnaeus after him, that the water-rat is web-footed behind. Now I have

discovered a rat on the banks of our little stream that is not

web-footed, and yet is an excellent swimmer and diver: it answers exactly

to the _mus amphibius_ of Linnaeus (see _Syst. Nat_.), which he says

"_natat in fossis et urinatur_." I should be glad to procure one

"_plantis palmatis_." Linnaeus seems to be in a puzzle about his _mus

amphibius_, and to doubt whether it differs from his _mus terrestris_;

which if it be, as he allows, the "_mus agrestis capite grandi

brachyuros_," of Ray, is widely different from the water-rat, both in

size, make, and manner of life.

As to the _falco_, which I mentioned in town, I shall take the liberty to

send it down to you into Wales; presuming on your candour that you will

excuse me if it should appear as familiar to you as it is strange to me.

Though mutilated "_qualem dices . . . ante hac fuisse tales cum sint

reliquiae_!"

It haunted a marshy piece of ground in quest of wild-ducks and snipes;

but, when it was shot, had just knocked down a rook, which it was tearing

in pieces. I cannot make it answer to any of our English hawks; neither

could I find any like it at the curious exhibition of stuffed birds in

Spring Gardens. I found it nailed up at the end of a barn, which is the

countryman's museum.

The parish I live in is a very abrupt, uneven country, full of hills and

woods, and therefore full of birds.
