all this, then, may be got at in a moment of time by the use of 

 this instrument. 



The gauge is formed of two brass cylinders eleven-sixteenths 

 of an inch in diameter and three and three-quarter inches in 

 length, one fitting or sliding within the other ; the inner one 

 is solid at each end, and has a gauge of weights cut on its sur- 

 face somewhat similar to those seen on the glass measures used 

 by apothecaries. On one side, extending the whole length of the 

 cylinder, is the grading for weighing the shot from one-fourth 

 ounce to three ounces; on the other side is the grading for 

 determining the weight of like proportions of powder, from 

 one-fourth drachm to seven drachms. 



When we wish to ascertain the weight of a certain propor- 

 tion of shot, all that is necessary is to lay hold of the rim that 

 encircles the end of the inner cylinder, and pull it (the cylin- 

 der) out sufficiently to leave space enough between the top of 

 the outer cylinder and the end of the inner cylinder, which is 

 now withdrawn within the outer one, so as to create the requi- 

 site vacuum for the shot to be measured or weighed. 



This being accomplished, the divisions of the grading cut on 

 the cylinder will show not only the required weight of the shot, 

 but also the exact weight of the same bulk of powder. 



This instrument is not of course as precise as a pair of fine 

 scales, but nevertheless is sufficiently correct for all ordinary 

 purposes. From the operations of this gauge, Ave have ascer- 

 tained that one ounce of shot will fill the same space as two 

 drachms and three-eighths of powder; one ounce and a half of 

 shot, within a fraction, of a space equal to three and a half 

 drachms; two ounces, within a fraction, equal to four' drachms 

 and three-quarters; three ounces, within a fraction, equal to 

 seven drachms ; and so on. 



NIPPLE OR PIVOT-WRENCH. 



This is a very useful and necessary instrument; indeed, no 

 Sportsman can consider himself properly equipped without one. 

 We have had several different kinds in the past few years, but 

 never had one till very lately that seemed to answer our pur- 

 pose in all respects. This wrench is made entirely of what is
