Q Do you take those into consideration in your calu-lations, the salts carried in solution? A Not in computing the quantity of material carried by the river. That is an entirely different proposition. Q Mr. Howard, is there any relation between the velo-cities of those rivers and the amount of silt which they are able to carry and do carry? A I do not know just how to answer your question. There is a relation between velocity and quantity of silt carried. But what that relation is, I have been unable to find in the studies that I have made. Q What I was trying to get at is, when the velocity of the river becomes sufficiently slow, then these suspended matters are deposited, are they not? A Yes, sir, that is true. Q Now, on these rivers, are you able to tell at what |
