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 fly- 

 wheel 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 Se- 

 potuba 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 carbureter could be attached 

 so that kerosene could be used it would add to its value 

 many times, for kerosene can be purchased almost any- 

 where in South America. 



Tents. — ^There is nothing better for material than 

 the light waterproof Sea Island cotton of American 

 manufacture, made under the trade name of waterproof 

 silk. It keeps out the heaviest rain and is very light.
