The tests consisted of gra- <br />dation analysis tests to determine the particle size distribution of <br />the samples. The test results are shown on Figures 1 and 2 attached. <br />As shown, all samples were considered to be non-plastic sands with the <br />percentages of fine material (-200 sieve) ranging from 1.4~ to 21.9%. <br />Gravel in the samples ranged from zero to 20.0 percent. <br />If you leave any questions cor~cer~~ing ti~~e laboratory tests or this letter, <br />please call. <br />Sincerely yours, <br />Allen G.
