August 10.—To day I prepared for another exploration to the N. W. and had all our casks and kegs new coopered and filled with water, to make them water tight. I found it necessary also to have our horses new shod, which was the third set of shoes they had required in less than two months, in consequence of the hard and stony roads over which we had travelled. The natives were again encamped near us at night, but did not come up.
