SELBORNE, _May 29th_, 1769.
Dear Sir,--The _scaraboeus fullo_ I know very well, having seen it in
collections, but have never been able to discover one wild in its natural
state. Mr. Banks told me he thought it might be found on the sea-coast.
On the 13th April I went to the sheep-down, where the _ring-ousels_ have
been observed to make their appearance at spring and fall, in their way
perhaps to the north or south, and was much pleased to see these birds
about the usual spot. We shot a cock and a hen; they were plump and in
high condition. The hen had but very small rudiments of eggs within her,
which proves they are late breeders; whereas those species of the thrush
kind that remain with us the whole year have fledged young before that
time. In their crops was nothing very distinguishable, but somewhat that
seemed like blades of vegetables nearly digested. In autumn they feed on
haws and yew-berries, and in the spring on ivy-berries. I dressed one of
these birds, and found it juicy and well-flavoured. It is remarkable
that they make but a few days' stay in their spring visit, but rest near
a fortnight at Michaelmas. These birds, from the observations of three
springs and two autumns, are most punctual in their return, and exhibit a
new migration unnoticed by the writers, who supposed they never were to
be seen in any southern countries.
One of my neighbours lately brought me a new _salicaria_, which at first
I suspected might have proved your willow-lark, but, on a nicer
examination, it answered much better to the description of that species
which you shot at Revesby, in Lincolnshire. My bird I describe thus: "It
is a size less than the grasshopper-lark; the head, back, and coverts of
the wings, of a dusky brown, without those dark spots of the
grasshopper-lark; over each eye is a milk-white stroke; the chin and
throat are white; and the under parts of a yellowish white; the rump is
tawny, and the feathers of the tail sharp-pointed; the bill is dusky and
sharp, and the legs are dusky; the hinder claw long and crooked." The
person that shot it says that it sung so like a reed sparrow that he took
it for one; and that it sings all night: but this account merits farther
inquiry. For my part I suspect it is a second sort of _locustela_,
hinted at by Dr. Derham in Ray's Letters: see p. 108. He also procured
me a grasshopper-lark.
The question that you put with regard to those genera of animals that are
peculiar to America, viz., how they came there, and whence? is too
puzzling for me to answer, and yet so obvious as often to have struck me
with wonder. If one looks into the writers on that subject, little
satisfaction is to be found. Ingenious men will readily advance
plausible arguments to support whatever theory they shall choose to
maintain; but then the misfortune is, every one's hypothesis is each as
good as another's, since they are all founded on conjecture. The late
writers of this sort, in whom may be seen all the arguments of those that
have gone before, as I remember, stock America from the western coast of
Africa and the south of Europe, and then break down the Isthmus that
bridged over the Atlantic. But this is making use of a violent piece of
machinery; it is a difficulty worthy of the interposition of a god!
"_Incredulus odi_."
TO THOMAS PENNANT, ESQUIRE.
THE NATURALIST'S SUMMER-EVENING WALK.
--equidem credo, quia sit divinitus illis
Ingenium.
VIRG. _Georg_.
When day declining sheds a milder gleam,
What time the may-fly haunts the pool or stream;
When the still owl skims round the grassy mead,
What time the timorous hare limps forth to feed;
Then be the time to steal adown the vale,
And listen to the vagrant cuckoo's tale;
To hear the clamorous curlew call his mate,
Or the soft quail his tender pain relate;
To see the swallow sweep the dark'ning plain
Belated, to support her infant train;
To mark the swift in rapid giddy ring
Dash round the steeple, unsubdued of wing:
Amusive birds!--say where your hid retreat
When the frost rages and the tempests beat;
Whence your return, by such nice instinct led,
When spring, soft season, lifts her bloomy head:
Such baffled searches mock man's prying pride,
The GOD of NATURE is your secret guide!
While deep'ning shades obscure the face of day,
To yonder bench leaf-shelter'd let us stray,
Till blended objects fail the swimming sight,
And all the fading landscape sinks in night;
To hear the drowsy dor come brushing by
With buzzing wing, or the shrill cricket cry;
To see the feeding bat glance through the wood;
To catch the distant falling of the flood;
While o'er the cliff th' awaken'd churn-owl hung
Through the still gloom protracts his chattering song;
While high in air, and poised upon his wings,
Unseen, the soft-enamour'd woodlark sings:
These, NATURE'S works, the curious mind employ,
Inspire a soothing melancholy joy:
As fancy warms, a pleasing kind of pain
Steals o'er the cheek, and thrills the creeping vein!
Each rural sight, each sound, each smell, combine;
The tinkling sheep-bell or the breath of kine;
The new-mown hay that scents the swelling breeze,
Or cottage-chimney smoking through the trees.
The chilling night-dews fall--away, retire!
For see, the glow-worm lights her amorous fire!
Thus, ere night's veil had half obscured the sky,
Th' impatient damsel hung her lamp on high:
True to the signal, by love's meteor led,
Leander hasten'd to his Hero's bed.
