Show Record the water than usual, and that is the only thing I saw on that trip which approached a sand wave. Below the Grand Canyon in 1923 I saw sand waves three or four feet high, which is the highest 2593 I have ever seen them. I observed some differences in the channel of the river between the up and down trip. In any sand bar river a heavy flow of water will facilitate the movement of sand and shift a sand bar. On this Colorado river trip I did not make any specific observation as to the location of any change in the channel between the up and downstream trip. We occasionally remarked that the channel had changed here and there, or we might have said that the water was shallower than it had been, but one takes that as a matter of course in any sand bar river; 2594 you get it anywhere. The only difference in this respect between the Colorado River and other sand bar rivers is that it is a little worse on the Colorado than on any other river I know of. Lewis Ransome Freeman testified on cross examination as follows: As I recall our Evenrude motors were three or four horsepower 2595 and my Elto motor was three horsepower. The only power, except man power, that each of our two units, consisting of two boats, had after the boats were lashed together was one Evenrude motor of three or four horsepower. Our down trip from Hall's Crossing was very much simpler and easier and attended with less obstructions and difficulties than was our upstream trip, because going downstream we had the power of the river running with us, whereas going upstream we were compelled to go against the power of the river; " just the difference the current makes, inseparable 2596 from all up and down stream navigation". With clean water you 2597 would have no motor trouble because of scouring. The outboard motor has no radiator. In response to questions propounded by the Special Master, Mr. Freeman testified as follows: I am not able to technically explain a difficulty encounter |
