 ground over carefully, and, accepting that the road is 

 all clear, we proceed to describe the stage which the-

 to a considerable extent, been copied by his friends. 

 Any watchmaker or machinist can do the work in>

 stage as large as your instrument will permit, and in 

 accordance with the above directions. 



Cut the well-hole one-sixteenth of an inch larger
