to the next notch and the auger turned until the gage again conies in contact with the top of 

 the tube, or, in other words, has removed one inch of soil, since the notches are one inch 

 apart. In this manner, a sample of soil from each inch may be obtained to a depth of 2 

 feet. Complete with auxiliary tube .' 9.00 



12356. SOIL AUGER, Pugh's. According to Dupont specifications this anger is especially designed for 



use in hard ground, and is the best tool on the market for penetrating the hard pan. It is 

 hand-made out of special steel, and actual tests made in all parts of the world have proved 

 that one Pugh will outwear and outbore a dozen or more of any other make. Useful for soil 

 sampling, tree planting, ditching, drainage and other earth boring where deep holes are re- 

 quired, or where the ground is hard. With extensions it can be lengthened so as to reach to 

 any desired depth; it is used very extensively for prospecting or for well boring, as well ac 

 for agricultural work. Length, 4% feet; weight, 10 to 12 pounds; bit, 1% inches in diam- 

 eter: complete with handle 18 to 21 inehhes long $5.10 



12357. EXTENSION for No. 12356 Soil Auger. Length, 3 feet 1.00 



12360. FOOT PLATE, for use with any Soil Auger 2 inches or less in diameter to prevent the crumb- 

 ling away of the soil around the edge of the hole. Consists of a steel tube slightly over 2 

 inches in diameter provided at the upper end with a steel plate about 4.5x10 inches. The 

 tube is driven into the ground before the sampling hole is started and the Plate makes a 

 convenient rest for the feet during the entire operation of removing samples 2.50 



12362. CARRYING CASE, for Auger Field Set, substantially made of hard black fiber with lock and 

 clasps, and handle for carrying. Compartments are provided for holding one No. 12346 Auger 

 (or one No. 12350 Auger), one No. 12348. Auger, two handles for the above, four No. 12351 

 Extensions, and a wrench for the lock nuts. Complete with Wrench, but without Augers or 



Extensions 7.50 



12:JG4. AUGER FIELD SET, consisting of No. 12362 Carrying Case with wrench, one No. 12346 Auger, 



one No. 12348 Auger, and four Xo. 12351 Extensions 27.00 



12366. AUGER FIELD SET, same as Xo. 12364, but with No. 12350 Auger instead of No. 12346. 27.00 

 12370. SOIL SAMPLING TUBE, King's. Tube of brass, 5 feet long, graduated every 6 inches. Cut- 

 ting head of steel with area of opening one-ten millionth of an acre. Steel collar at top to 

 receive blows of hammer shown in illustration. This hammer is of east iron, weighing 8 

 pounds, and is of suitable shape to be held easily in the hand. 



To obtain soil samples the tube is driven into the ground to the desired depth by means of the 

 hammer. A column of soil is thus forced up into the tube from which it is jarred after re- 

 moval from the ground. The outside of the cutter being larger than the tube allows it to 

 be drawn from the ground more easily. If, however, the tube is not withdrawn from the 

 ground with sumcient readiness, No. 12374 Tube Hoist should be used.

12372. SOIL SAMPLING TUBE, King's, same as No. 12370, but 3 feet long. With hammer. . . 7.00 



1878. SAMPLING TUBE BRUSH, for cleaning Nos. 12370 and 12372 Soil Sampling Tubes. Bristle 



brush, with strong wire handle. Total length, 65 inches .25
