reaping,
are often so blistered and corroded as to prevent their working. It also
has been known to blister the mouths and nostrils of cattle when feeding
where it grows.

658. COLCHICUM autumnale. MEADOW-SAFFRON.--This is a common plant in
pasture-land in Worcestershire, Herefordshire, and other counties. Many
are the instances that have occurred of the bad effects of it to cattle.
I have this last autumn known several cows that died in consequence of
eating this plant.

659. MELILOT. Trifolium officinale.--This plant when eaten by cows
communicates a disagreeable taste to milk and butter.

660. ROUND-LEAVED SUN-DEW. Drosera rotundifolia.--Very common on marshy
commons, and is said to be poisonous to sheep, and to give them the
disease called the rot.

661. SEA BARLEY-GRASS. Hordeum maritimum.--This grass has been known in
the Isle of Thanet and other places to produce a disease in the mouths
of horses, by the panicles of the grass penetrating the skin.

662. WATER-HEMLOCK. Phellandrium aquaticum.--Linnaeus informs us that the
horses in Sweden by eating of this plant are seized with a kind of
palsy, which he supposes is brought upon them, not so much by any
noxious qualities in the plant itself, as by a certain insect which
breeds in the stalks, called by him for that reason Curculio
paraplecticus [Syst. Nat. 510]. The Swedes give swine's dung for the
cure.

663. YEW. Taxus baccata.--This is poisonous to cattle: farmers and other
persons should be careful of this being thrown where sheep or cattle
feed in snowy weather. It is particularly dangerous to deer, for they
will eat of it with avidity when it comes in their way.

SECTION XV.--PLANTS NOXIOUS IN AGRICULTURE.

Annual Weeds, or such as grow wild in Fields, and that do not produce
any Food for Cattle.

Many weeds are troublesome to the farmer amongst his crops; but which,
by affording a little fodder at some season or other, in some degree
compensate for their intrusion. But as the following are not of this
description, they ought at all times to be extirpated: for it should be
recollected, that the space occupied by such a plant would, in many
instances, afford room for many ears of wheat, &c.

The following are annuals, and chiefly grow among arable crops, as corn,
&c. As these every year spring up from seeds, it is a very difficult
matter for the farmer to prevent their increase
