ased in two sizes and nested for transportation, an
arrangement which would save considerable expense in freight bills. At
least six paddles should be packed with each boat, in length four and
one half, four and three fourths, and five feet. Other paddles from
six and one half feet to eight and one half feet should be provided
for steering oars. The native paddler, after he has used the light
Canadian paddle, prefers it to the best native make. My own paddlers
lost or broke all of their own paddles so as to get the North American
ones, which they marked with their initials and used most carefully.

To each canoe it would be well to have two copper air tanks, one fore,
one aft, a hand-hole in each with a water-tight screw cover on hatch.
In these tanks could be kept a small supply of matches, the
chronometer or watch which is used for position, and the scientific
records and diary. Of course, the fact should be kept in mind that
these are air tanks, not to be used so as to appreciably diminish
their buoyancy. Each canoe should also carry a small repair kit
attached to one of the thwarts, containing cement, a piece of canvas
same as cover of canoe, copper tacks, rivets, and some galvanized
nails; a good hatchet and a hammer; a small can of canoe paint, spar
varnish, and copper paint for worn places would be a protection
against termites and torrential downpours. In concluding the subject
of canoes I can state that the traveller in South America will find no
difficulty in disposing of his craft at the end of his trip.

MOTORS--We had with us a three and one half horse-power motor which
could be attached to stern or gunwale of canoe or boat. It was made by
the Evinrude Motor Company, who had a magneto placed in the flywheel
of the engine so that we never had to resort to the battery to run the
motor. Though the motor was left out in the rain and sun, often
without a cover, by careless native help, it never failed us. We found
it particularly valuable in going against the strong current of the
Sepotuba River where several all-night trips were made up-stream, the
motor attached to a heavy boat. For exploration up-stream it would be
valuable, particularly as it is easily portable, weighing for the two
horse-power motor fifty pounds, for three and one half horse-power one
hundred pounds. If a carburetor could be attached so that kerosene
could be used it would add to its value many times, for kerosene can
be purchased almost a
