part rising higher than the Females, and frequently falling and flapping
them with their Wings, which produces a noise that one may hear a great
way; from whence it happens that their Quill-Feathers are commonly broken
or shatter'd. These are almost like the Pigeon call'd the Tumbler; the
difference chiefly is, that the Tumbler is something smaller, and in its
flight will turn itself backward over its Head. The diversity of colours in
the Feathers makes no difference.

The Helmet is another kind of Pigeon distinguish'd from the others, because
it has the Head, the Quill-Feathers, and the Tail-Feathers always of one
colour: Sometimes black, sometimes white, or red, or blue, or yellow; but
the other Feathers of the Body are of a different colour.

The next Pigeon I shall take notice of, is that which is call'd the light
Horseman; this is supposed to be a cross strain between a Cock Cropper and
a Hen of the Carrier Breed, because they seem to partake of both, as
appears from the exerescent Flesh on their Bills, and the swelling of their
Crops; but I am not determin'd concerning that point, nor can give any good
Judgment about it, till I have seen whether the Cropper be the Male or
Female, upon which depends a Debate in Natural Philosophy, which has not
been yet decided; this sort however is reckon'd the best Breeder, and are
not inclin'd to leave the place of their Birth, or the House where they
have been accustom'd.

The _Bastard-bill Pigeon_ is another sort, which is somewhat bigger than
the _Barbary_ Pigeon; they have short Bills, and are generally said to have
red Eyes, but I suppose those colour'd Eyes are belonging only to those
which have white Feathers.

There is also a Pigeon call'd the _Turner_, which is said to have a Tuft of
