bosomy

[…] I beheld, in momentary sun, / One of thy hills gleam bright and bosomy, / Just like that orb of orbs, a human one, / Let forth by chance upon a lover's eye.

The essence of a tandem team is surely that it should be well balanced, sporting in appearance and that the horses themselves should at all events convey the impression of being able to do a long stage with ease and comfort. Now there can be nothing "sporting" about a beefy, bosomy, bad-shouldered tandem leader, who picks his fore feet up as high as he can, hangs them down again with a straight thrust on the ground, but a very little distance in advance of the spot from which he took them up.
