The elevation of the sea then was about 40 to 50 feet low- er. Cape town water sources to- day are located in these runs or gullies, and here the soil material is "sorted", and these are the best sources for well water. The lakes and ponds were formed when bur- ied ice melted and made the de- pressions or "pot ; It is in some of these pot holes which were later filled with peat, that the growers have their bogs. Areas of some of these depressions, es- pecially along the edges, may be fair water sources. Ponds in gen- eral are not "sorted" material and especially along the backbone, and these areas are not good locations in which to seek water. The soil material to be looked for is coarse sand, such as that in dunes, he said. Wells could go down 40 or 50 feet, below present sea level. Wells Would Replenish He said he understood 100 gal- lons a minute was necessary for one acre for frost irrigation, and to irrigate a 5 acre section should not be much of a problem and that probably 10 wasn't too much of a one. A single well which supplied only 10 gallons a minute is poor, one which supplies 20 fair, 40 good, and 80 or better, excellent. He said with a five hour irrigation for frost, growers need not worry about replenishment of the well for the following night. Technical Discussion He then technically discussed the procedures for testing to locate a well water supply, and said he preferred the "open-end" method, using 2V2 inch pipe, preferably of wrought iron, with couplings of malleable iron, not cast iron. Driving can be by any method, usually with an engine and "nigger head" drum. He told how to "wash" the material so the soil could be sampled. One of the surest signs of water, he said, was when this w
