A boy stoops so that his arms rest on a table; another boy sits on him as he would on a horse. He then holds up (say) three fingers, and says—

Buck, buck, how many horns do I hold up?

The stooping boy guesses, and if he says a wrong number the other says—

[Two] you say and three there be;
Buck, buck, how many horns do I hold up?

When the stooping boy guesses rightly the other says—

[Four] you say and [four] there be;
Buck, buck, rise up.

The boy then gets off and stoops for the other one to mount, and the game is played again.—London (J. P. Emslie).

Similar action accompanies the following rhyme:—

Inkum, jinkum, Jeremy buck,
Yamdy horns do au cock up?
Two thà sès, and three there is,
Au’ll lea’n thee to la’ke at Inkum.

—Almondbury (Easther’s Glossary).
