240 THE AMERICAN MUSEUM JOURNAL This flooding of ground formerly high and dry, it was anticipated, would drive many animals to seek new homes or might even threaten some of the more restricted, lowland-living animals with extermination. Incidentally many of the islands and ridge crests left above water might have a concentrated fauna driven there from the adjacent flooded localities. Other phases of the question dealing with the newly created lake, were vestigation, it was planned to work from a house boat as a base camp with a launch and small boats for side trips. Accordingly a boathouse was made over by a few alterations, but only after considerable time had been spent in trying to secure something available for the purpose. The house boat was so low in the water that she could be towed only in a calm sea, a condition of the lake only rarely met with, and at the best

It was because of the flooding of the Gatun Lake basin by the huge dam at the Gatun lociis, thus causing abrupt changes in the faunal conditions, tliat an expedition under the patronage of Mr. George Shiiras, 3d, was undertalien. The liouse-boat formed the base camp from which trips were made by launch or small boat, sometimes along rivers wliich heretofore have been inaccessible owing to shallow water. The house-boat had sides of cheese cloth and copper screen to keep out mosquitoes the wiping out of the lowland forests by submergence, the rise of new aquatic flora such as the water hyacinth, and the probable inhabitation of the lake by water birds. Such were some of the items in the purpose of the expedition and we were equipped to take advantage of these new conditions if the foregoing assumptions proved correct. As Gatun Lake was the center of in- the launch could make but slow time pulling her. Late afternoon of March 6 saw us leaving Gatiin with the house boat and by three o'clock the next morn- ing we were tied up at the head of a water-way or trocha that branched off from the Rio Trinidad. This was our main camp and we hoped to be able to work the undisturbed jungle from here. Unfortunately, a plantation near by, a
