Solitary Sandpipers, some Killdeer, one or two Wilson's Snipe and a Kingfisher.

There were also two sets of Vermilion Flycatcher taken. Will shot a Pygmy Owl. About now the 'trail' became exceedingly rough and we had to stop collecting.

At about dusk we came to a small flat piece of ground, where there was plenty dry wood, and we decided to camp there for the night, as we did not know how much further we would have to go.

It is called the Basin from the fact that three or
