Show Record was just as heavily laden with solid matter at the surface as it 3855 was near the bottom. I did testify that it required great care in obtaining the samples. I took them in such a way that they would represent the vertical cross section of the river at that point, and raised the sampler from the bottom to the top at a uniform rate of speed so that a portion of the sediment from near the bottom greater than would represent what the river was carrying would not drop into the sample. If it were delayed at that point an excess might drop in that would not represent that point. 3856 The only way with which I took care in obtaining the samples was in so moving the bottle that there would not be dropped into it any extra amount or one piece that would make the sample an unfair sample. In taking may samples there was a necessity, in order to get an accurate sample, that the water from the entire stream along a given line from top to bottom be contained in the sample, instead of the water from the top or the bottom alone, because the water at the bottom of the stream was more heavily laden with solids than the water at the top of the stream. I did not take into consideration that the water and bed at that point were stirred up by the 100 pound weight, or by any other method, because I did not think it would make any difference. I do not 3858 believe the weight stirred it sufficiently to materially make a difference in the amount in the sample, and I took no care to avoid the effect of any stirring up that may have been occasioned by the taking of the depth soundings, and without having that in mind I put down my bottle to get my sample, and that is the way 3859 I did when I got my 40 percent sample. Samuel Kenneth Love testified on re- direct examination as follows: The weight is a torpedo- shaped weight, a standard weight used by the engineers making discharge measurements on all gaging stations. It is 5 to 7 inches wide and about 18 inches long. It was on a windlass and connected with a wire. I let the weight |
