The steam-whistle and gong had startled them at first, but they had tested their harmless natures, and evidently thought the howitzers relatives, whose destructiveness could be avoided as easily as the poison of their arrows when they had obtained a knowledge of the antidote. The forbearance of the captain had favored this impression, and it was determined in consultation to use our weapons to the full extent of their destructiveness. An opportunity was soon offered, for in passing a raft lodged on the eastern shore Waantha pointed out a rampart of logs ready poised for an overthrow, with interstices between in which were seen the protruding muzzles of their blow-pipes. One of the mountain howitzers loaded with solid shot was discharged point-blank against the upper tier causing it to fall inward, catching the lurking savages in their own trap, while it exposed those in the rear to the full effect of grape and our small arms, which caused the river echoes to resound with the yells of the wounded. Without stopping to learn the extent of the slaughter, the steamer kept on her course. In passing a glade reaching to the water the plain was seen covered with panic- stricken savages on foot and horseback, directing their course to the foot-hills. Although surprised at the large number collected, we felt safe with the impression that the wood rafts of the left bank would be left free for our acceptance thereafter. _June 14._—While collecting wood from the scattered lodgments of the western bank, parties of mounted Indians watched our movements from the opposite plain. These Waantha informed us were of his own tribe. When asked if he would like to be set on shore to rejoin them, he expressed, with signs, a reproachful negative, blended with fear and sorrow. After a moment’s hesitation he seemed to understand that the proposal was made to test his feelings, then with a pleased look of Indian cunning he pointed to the old chief, who had been regarding him with a revengeful look of ferocity. Understanding his meaning as a proposal of substitution, Mr. Welson asked, through Aabrawa, if they would kill the old chief if set on shore? This was answered with a decided negative, and the pantomimic addenda of labor as a substitute for death. As the captive was sufficiently recovered from his wounds to control his own movements, Mr. Welson took him in charge for initiatory preparation in presage for association with his foes on shore. That it might not, in form, be considered an arbitrary expedient for riddance, after Mr. Parry had fitted to his neck a brass collar, proof to Indian appliances for removal, he was freed from his bonds under the supervision of Mr. Welson, who offered him his choice between the continued hospitalities of the steamer, or liberty, such as he might be able to secure from his congeners on either bank of the river? The speedy announcement of his choice was urged by three strong shocks of the battery. When his
