HKALD s bridge: machu picchu 



The completed bridge over the rapids of the Urubamba, showing the forked upright 

 still in place. The great difficult}- in building this bridge lay in the fact that the timber was 

 of such density that it would not float. 



thrust out over the water toward 

 rock Xo. 2, the end being held up 

 by a rope fastened around it and 

 passing through the fork of the 

 upright (see Fig. 2, page 422). 



"This method proved success- 

 ful, the timber's end being laid on 

 the rock which formed our second 

 pier. Two more light timbers 

 were put across this way, and then 

 a heavy one was tried, part of its 

 weight being borne by the pieces 

 already across by means of a yoke 

 locked in the end (see Fig. 3). 

 This and another piece were suc- 

 cessfully passed over, and after 

 that there was little trouble, cross- 

 pieces being used to form the next 

 and shorter span. 



"( )n the second day of work we 

 finished the bridge about noon and 

 started making a trail up the hill 

 under the guidance of a half- 

 breed who lived in the vicinity. 

 After the first quarter mile the 

 going was very slow. Not only 

 did the steepness of the slope and 

 the tangled condition of the cane 

 jungle retard us. but the men were 

 very much afraid of snakes, a fear 

 which proved itself justified, for 

 one of them was very nearly bit- 

 ten by a little gray snake about 12 

 inches long.
