    January 17* 19^ Mr. J. M. Anderson? (CO I Mr. J. P. Mack) . 1 have the following from Mr. R. Edwards under date of January 15th: "There is something wrong with No. 6 well to cause it to mud up the way it does. I haven't used it on the pump the last two summers for this reason. X would clean it up and turn into reservoir - it would he OK for three weeks* and then mud up badly. X could not rely on it* as this condition might happen at night and then the whole water supply would be in bad condition. There is something wrong in the bottom casing. This well should be put In shape as we are going to need all the water we can get with the pump working. Mr. J. M. Ander- son suggested that X put this pump on and clear it up - X have done this for a week. The pumping doesn't do HE any good." X think without doubt this well bottoms in a permeable structure, and that the heavy pull of pumping so Increases the velocity through the perforations that fine sand is dislodged and drawn in through the liner. Xn my opinion the answer to this is to discontinue use of the pump and allow the well to operate on artesian pressure. I do not think we will be short of water next summer, but if there is any indication of such shortage we can remove the pump and install it in Well No. 9* or some other well where we think it will operate successfully. I am instructing Mr. Edwards to discontinue use of the pump on No. 6 and to keep that well flow­ing continuously for the present, observing its performance closely. Will appreciate if you will also watch developments. As sand has been pulled into Well No. 6, it is possible the bottom is sanded up to some extent, and the next time we have equipment on the ground for cleaning and swabbing we will run a line in this well and, if sanded up, clean it out. i®f|l' Los Angeles - Prank Strong
