Some of them are sucking away like old topers.

Some of them are setting up on their tails and hind legs, fiddling with their fore-feet and wiping their eyes.

Some are rolling around on the ground, contented.

There are quantities of big blue-bottle flies over the bark and hanging on the grasses around, too drunk to steer a course flying; so they just buzz away like flying, and all the time sitting still.

The snake-feeders are too full to feed anything--even more sap to themselves.
