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.
