LETTER XVII.

RINGMER, near LEWES, _Dec._ 9_th_, 1773.

Dear Sir,--I received your last favour just as I was setting out for this

place, and am pleased to find that my monography met with your

approbation. My remarks are the result of many years' observation, and

are, I trust, true in the whole, though I do not pretend to say that they

are perfectly void of mistake, or that a more nice observer might not

make many additions, since subjects of this kind are inexhaustible.

If you think my letter worthy the notice of your respectable society, you

are at liberty to lay it before them, and they will consider it, I hope,

as it was intended, as a humble attempt to promote a more minute inquiry

into natural history, into the life and conversation of animals. Perhaps,

hereafter, I may be induced to take the house-swallow under

consideration, and from that proceed to the rest of the British

hirundines.

Though I have now travelled the Sussex Downs upwards of thirty years, yet

I still investigate that chain of majestic mountains with fresh

admiration year by year, and I think I see new beauties every time I

traverse it. This range, which runs from Chichester eastward as far as

East Bourn, is about sixty miles in length, and is called the South

Downs, properly speaking, only round Lewes. As you pass along you

command a noble view of the wild, or weald, on one hand, and the broad

downs and sea on the other. Mr. Ray used to visit a family just at the

foot of these hills, and was so ravished with the prospect from Plumpton

Plain, near Lewes, that he mentions those scapes in his "Wisdom of God in

the Works of the Creation" with the utmost satisfaction, and thinks them

equal to anything he had seen in the finest parts of Europe.

For my own part, I think there is somewhat peculiarly sweet and amusing

in the shapely-figured aspect of chalk-hills in preference to those of

stone, which are rugged, broken, abrupt, and shapeless.

Perhaps I may be singular in my opinion, and not so happy as to convey to

you the same idea; but I never contemplate these mountains without

thinking I perceive somewhat analogous to growth in their gentle

swellings and smooth fungus-like protuberances, their fluted sides, and

regular hollows and slopes, that carry at once the air of vegetative

dilation and expansion . . .

. . . Or was there ever a time when these immense masses of calcareous

matter were thrown into fermentation by some adventitious moisture: were

raised and leavened into such shapes by some plastic power: and so made

to swell and heave their broad backs into the sky so much above the less

animated clay of the wild below?

By what I can guess from the admeasurements of the hills that have been

taken round my house, I should suppose that these hills surmount the wild

at an average at about the rate of five hundred feet.

One thing is very remarkable as to the sheep: from the westward till you

get to the river Adur all the flocks have horns, and smooth white faces,

and white legs, and a hornless sheep is rarely to be seen; but as soon as

you pass that river eastward, and mount Beeding Hill, all the flocks at

once become hornless, or as they call them, poll-sheep; and have,

moreover, black faces with a white tuft of wool on their foreheads, and

speckled and spotted legs, so that you would think that the flocks of

Laban were pasturing on one side of the stream, and the variegated breed

of his son-in-law Jacob were cantoned along on the other. And this

diversity holds good respectively on each side from the valley of Bramber

and Beeding to the eastward, and westward all the whole length of the

downs. If you talk with the shepherds on this subject, they tell you

that the case has been so from time immemorial; and smile at your

simplicity if you ask them whether the situation of these two different

breeds might not be reversed? However, an intelligent friend of mine

near Chichester is determined to try the experiment; and has this autumn,

at the hazard of being laughed at, introduced a parcel of black-faced

hornless rams among his horned western ewes. The black-faced poll-sheep

have the shortest legs and the finest wool.

As I had hardly ever before travelled these downs at so late a season of

the year, I was determined to keep as sharp a look-out as possible so

near the southern coast, with respect to the summer short-winged birds of

passage. We make great inquiries concerning the withdrawing of the

swallow kind, without examining enough into the causes why this tribe is

never to be seen in winter; for, _entre nous_, the disappearing of the

latter is more marvellous than that of the former, and much more

unaccountable. The hirundines, if they please, are certainly capable of

migration, and yet no doubt are often found in a torpid state; but

redstarts, nightingales, white-throats, black-caps, etc., are very ill

provided for long flights; have never been once found, as I ever heard

of, in a torpid state, and yet can never be supposed, in such troops,

from year to year to dodge and elude the eyes of the curious and

inquisitive, which from day to day discern the other small birds that are

known to abide our winters. But, notwithstanding all my care, I saw

nothing like a summer bird of passage; and what is more strange not one

wheat-ear, though they abound so in the autumn as to be a considerable

perquisite to the shepherds that take them; and though many are to be

seen to my knowledge all the winter through in many parts of the south of

England. The most intelligent shepherds tell me that some few of these

birds appear on the downs in March, and then withdraw to breed probably

in warrens and stone-quarries: now and then a nest is ploughed up in a

fallow on the downs under a furrow, but it is thought a rarity. At the

time of wheat-harvest they begin to be taken in great numbers; are sent

for sale in vast quantities to Brightelmstone and Tunbridge; and appear

at the tables of all the gentry that entertain with any degree of

elegance. About Michaelmas they retire and are seen no more till March.

Though the birds are, when in season, in great plenty on the south downs

round Lewes, yet at East Bourn, which is the eastern extremity of those

downs, they abound much more. One thing is very remarkable, that though

in the height of the season so many hundreds of dozens are taken, yet

they never are seen to flock; and it is a rare thing to see more than

three or four at a time; so that there must be a perpetual flitting and

constant progressive succession. It does not appear that any wheat-ears

are taken to the westward of Houghton Bridge, which stands on the river

Arun.

I did not fail to look particularly after my new migration of

ring-ousels, and to take notice whether they continued on the downs to

this season of the year; as I had formerly remarked them in the month of

October all the way from Chichester to Lewes wherever there were any

shrubs and covert: but not one bird of this sort came within my

observation. I only saw a few larks and whin-chats, some rooks, and

several kites and buzzards.

About Midsummer a flight of cross-bills comes to the pine-groves about

this house, but never makes any long stay.

The old tortoise, that I have mentioned in a former letter, still

continues in this garden; and retired under ground about the 20th

November, and came out again for one day on the 30th: it lies now buried

in a wet swampy border under a wall facing to the south, and is enveloped

at present in mud and mire!

Here is a large rookery round this house, the inhabitants of which seem

to get their livelihood very easily; for they spend the greatest part of

the day on their nest-trees when the weather is mild. These rooks retire

every evening all the winter from this rookery, where they only call by

the way, as they are going to roost in deep woods: at the dawn of day

they always revisit their nest-trees, and are preceded a few minutes by a

flight of daws, that act, as it were, as their harbingers.
