Roosevelt was not pleased with the fixed-station survey. Not only did it slow the expedition to a glacial pace—the boats traveled only six miles in five hours—but it placed his son in a particularly dangerous position. If there were sunken trees, hidden whirlpools, sudden waterfalls, or hostile Indians, Kermit would encounter them first. In spite of his concerns, however, Roosevelt refrained from asking Rondon to adopt a faster method of survey.
