The bull is led into the ring from outside by a lasso.

It is then lassoed from behind and dragged up to a post or tree, to which it is firmly tied to prevent its moving.

A rope is then tightly cinched about its middle and a man mounts upon the back of the beast, fixing his feet firmly in the rope below, between it and the animal, and winding his hands into it above.

The ropes which hold the bull are then withdrawn so as to set it loose.

Dozens of men and big boys, with jackets and _serapes_, then torment the beast, which, plunging and dashing at them, scatters them in every direction.
