To this I tied my main beam by a strong cord, loose enough to turn round the trunk.

Another cord was attached to the opposite end of the beam, long enough to cross the river twice.

I took the end of my rope over the stream, where we had previously fixed the block, used in our boat, to a tree, by the hook which usually suspended it.

I passed my rope, and returned with the end to our own side.

I then harnessed my cow and ass to the end of my rope, and drove them forcibly from the shore.
