COPPER, STEEL, AND BANK-NOTE ENGRAVING. 611 



Figs. 14 and 15 will show some of the more complicated designs 

 and effects that may be had from one of these lathes. These look 

 to be very complicated, but are, in reality, quite simple : Fig. 14 

 having but five continuous lines, including the two plain circles

 being produced by the crossing and interlacing of the lines. 



Some of the cuttings used for bank notes appear to have thou- 

 sands of lines, but very few of them have more than twenty, and 

 most have but three or four. 



The above diagrams have been engraved for this article by the 

 lathe itself. They have been purposely made much more simple 

 than those used in the bank-note business, in order that the gen- 

 eral form may be more readily distinguished. Any one with a

 figures. 



One peculiarity of lathe- work should be noted. We said, in a 

 former paragraph, that in steel-plate engraving the line cut by the 

 graver prints black. In most of our diagrams, as well as on the 

 notes themselves, the line is white the interspaces being black.
