 be pressed down so as to rest smoothly

 from working und^r them. 



The tarred pads can be obtained from 

 seedsmen and dealers in garden sup-

 himself by using the tool shown in 

 Fig. 31. The method is described by 

 Goff as follows : 



"The blade of the tool, which should

 formed from a blade of steel, bent in 

 the form of a half hexagon, and then taking an acute angle, 

 reaches nearly to the center. The part making the star-shaped 

 cut is formed from 

 a separate piece 

 of steel, so at- 

 tached to the 

 handle as to make 

 a close joint with 

 the blade. The 



latter is beveled from the outside all around, so that by remov- 

 ing the part making the star-shaped cut, the edge may be 

 ground on a grindstone. It is important that the angles in 

 the blade be made perfect, and that 

 its outline represents an exact half 

 hexagon. 



"To use the tool, place the tarred 

 paper on the end of a section of a log 

 or piece of timber and first cut the
