`` Then our ponies have certainly passed here , and Vic was on their trail when we saw her coming from the Tanks , '' remarked Frank ; `` but there could have been no scent after so long a time . '' `` Oh , she knows Sancho 's and Chiquita 's tracks , '' asseverated Henry ; `` she knows their halters , bridles , and will bring them when told to , without mistake . '' The sentinel awakened us next morning at four o'clock , and informed us that the Indians had left two hours before . The animals were again driven to the Tanks , the vessels and canteens filled , and at six o'clock we were on the road . Nearly all our water was used in the preparation of breakfast , except that in the canteens . It would have been better if we had made a third trip to the cisterns and refilled our coffee-pot and camp-kettles ; but the delay necessary to do it , and the assurance that there was water at Hole-in-the-Plain , determined me to go on at once . The weather was a repetition of that of the previous day -- hot and windless .
