EL Karstom 1955 Bufo coronus Oct. 22 re-testing and digging until we hit the level 16" below the surface of the meadow. Use a shovel full of loam and root structure tested >1200 c.p.s., with Geiger counter. The hole we had dug tested definitely negative (the normal background of 30-40 c.p.s.) The first shovel load was subdivided into 5-6 sub-samples. One small tangle of roots were "hot" - all others negative, but we could see no tablet so questioningly wondered if this was another example of selective absorption by roots of a radioactive element. Later Jim Anderson shot a mountain wessel with a .22 shot rifle, wounded it, and we began to dig up the granite slabs in ground where last tablet found. The radioactive dirt had been written off as a damnable puzzle. 3:20 P.M. I decided to try the dirt samples once more. This time I got it down to a few spoonful of dirt - and the radioactive slug (not numbered - probably one of first I used) was found lying on the granite boulder where the sub-samples had been laid. Soil saturated with water from point 2" below surface to 18" depth. Congeation is wet loam soil tangled with roots of sedge or swamp prim to a depth of approximately 18-20". At this point we struck a large angular boulder which would be impossible to move. While struggling to capture the injured wessel we were able to peer down a good 20" by prying a large granite to our side. It was sopping wet indicating that the water table
