entire layer may be pulverized, but 

 do not go below the bottom of it, as the 

 force of the blast will tend to raise 

 the hardpan in chunks rather than 

 shatter it. The depth is governed ab- 

 solutely by the depth of the hardpan. 



Illustration "C," Fig. 1, shows one 

 of the most common subsoil troubles. 

 This type of hardpan or tight clay is 

 usually too deep to blast through and 

 relief is obtained by pulverizing sev- 

 eral feet of the top, which if well done 

 will be found to be sufficient to store 

 moisture and furnish room for an 

 ample root development. For such a 

 condition the blast should be made not 

 less than three feet deep. 



Occasionally a soil is found like that 

 shown in "D," Fig. 1, which will 

 usually be found to require deeper 

 blasting. The explosive should be 

 placed well down in the hardpan — the 

 deeper the better. 



When very deep loading is prac- 

 ticed it is best to increase the amount 

 of the charge, sometimes to more than 

 double the amount normally used.

Making Bore Holes. — A number of 

 different methods have been devised 

 for making the bore holes for loading, 

 but so far no other tool has given such 

 good results as a heavy subsoil punch 

 Fig. 2. This tool is made of iy2-inch 

 steel and should be not less than three 

 feet long. Smaller drills will not be 

 satisfactory, as the explosive cartridge 

 is itself 1 Vi inches in diameter and 

 when primed with cap and fuse is dif- 

 ficult to load into a smaller hole. The 

 punch is driven to the desired depth 

 with a sledge, and loosened by pound- 

 ing on the sides, after which it can 

 easily be withdrawn. 



A soil auger is quite satisfactory 

 for making a small number of holes, 

 but is too slow and expensive if there 

 is much work to be done. However, 

 for holes deeper than three feet, one 

 can be used very satisfactorily to 

 deepen the drilled holes. In some 

 cases holes can be made with a heav>- 

 crowbar. Some soils are so hard, be- 

 ing in reality soft rock, that a rock 

 drill is re(iuired to make the holes. 



Prepuving the Ctiarge. — The charge 

 is prepared by cutting off a piece of 

 fuse as long as the hole is deep, and 

 crimping a cap on one end by means 

 of a cap crimper. The cap with the

C ECURITY 



Ladd^ 



— I'll pay the freight and ship subject to approval, 

 C. O.D. The Security never comes back! I've 

 sent hundreds on approval — not one was ever 

 returned. Orchardists know when they see the 

 Security it is the one ladder that actually cuts 

 picking costs and is built right. 



— The patented steel cuff-bracket grips each 

 step-end, making Security strongest where other 

 ladders are weakest. The greatest feature ever 

 put on a ladder, because by saving picker's time 

 it reduces your picking costs, boosts your profits. 

 Picker feels secure on a ladder that cannot wob- 

 ble. Does not spend his time in running up and 

 down so change position of ladder. 



— But even without this feature the Security 

 would appeal to you because it is built right all 

 through. Light, strong, plenty of spread. All 

 wood vertical grain, and the steps are easily 

 replaceable. Swinging back-leg hinged metal-to- 

 metal eliminates side-sway.
