Frank and Fred assented readily to the proposal; in fact, they never did anything else when the Doctor gave advice or suggestions.

But it was easier to agree to build a hut than to build it. Labor was not easy to obtain.

AN AMAZONIAN DWELLING.

The forest supplied the material, but it was difficult to induce the Indians to do anything. After considerable argument they prevailed upon some of the men to cut the requisite bamboos, and bring them to the spot selected for the temporary dwelling. Under the supervision of the youths and their guide, the walls were put up by driving some of the bamboos into the ground; a space was left for a doorway; the roof was put on, and thatched with leaves of the Pandanus palm; and by nightfall the new house was completed. It measured about twelve feet by fifteen, and was admirably ventilated; the total cost was estimated at six dollars and a half, and it was pronounced one of the handsomest structures in the village. The Indians were well paid for their labor, according to the rates of the local trades union; and it was understood that the building was to become the property of the alcalde, or chief man of the village, after the departure of the strangers.

The alcalde surveyed the edifice with evident pride, and the Doctor thought he discovered an avaricious expression on the fellow's face. Frank and Fred thought likewise.

"I tell you what it is," said Fred, "we have 'builded wiser than we knew.' He will be anxious enough to get us away in order to take possession of his new residence."

"I was thinking the same thing," said Frank, "and we shall save more than the cost of the building when we make our bargain with the alcalde for boats, to go down the river."
