MR. EVANS: Mr. Chairman: The question arises as to what kind of dynamite to use in the different soils. Most pecan land contains clay and can best be worked by dynamite. Don't buy ordinary dynamite, because it is too high an explosive. For several reasons it is not the kind of an explosive you wish. In some places dynamite can hardly be put on the market as many people are afraid of it and so the word dynamite has been eliminated, and we now have what we call Red Cross Farm Powder. It will work in any part of the country, it is not a high explosive and the price is lower as the hardware dealers have it direct from the Dupont companies. By using this Red Cross Farm Powder, less labor is required and it doesn't cost very much. For labor and all it will cost you about five cents per hole, and that includes the dynamite caps, fuse and labor. PROFESSOR SMITH: How much do you use? MR. EVANS: That depends on the soil and also on the depth to which you want to shoot the hole. Nurserymen have different opinions on that subject, but in the southern field where I have been working they usually go from two and a half to three feet deep. They use one-half stick 20 per cent dynamite, or one quarter of a pound as it weighs two sticks to the pound. That should make a hole two and a half or three feet deep. Fuse is cheap and you should use plenty of it. A man has to be governed always by the kind of soil he is dealing with. MR. POMEROY: In shooting an old apple orchard how deep would you go? MR. EVANS: Where I have been working from three and a half to four feet, but as I said before it will depend largely on the soil. MR. POMEROY: How far from the body of the tree? MR. EVANS: I have never made a study of that. MR. POTTER: In limestone soil, for instance, built up with clay, how near the trees would you use the dynamite if you want to loosen up the soil? MR. EVANS: What kind of trees? MR. POTTER: Pecan. MR. EVANS: About six feet. I think that is close enough. MR. POTTER: Would you make more than one hole around the tree? MR. EVANS: Use your own judgment about that. MR. POTTER: How far out will it loosen or break up the ground? MR. EVANS: Probably six feet. You can distinguish on the top of the ground where it takes place. MR. POTTER: How deep will it be? MR. EVANS: About a foot deeper than the charge is placed.
