But perhaps the most satisfactory way of all is making a port- 

 folio of leaf prints. The tools needed are a large, smooth, slate or 

 better still, a thick plate of glass, measuring about twelve to fifteen 

 inches and costing fifteen or twenty cents ; a tube or jar of printer's 

 ink, either green or black in color and costing fifty cents, the one 

 tube containing a sufficient supply of ink for the making of several 

 hundred prints; and two six-inch rubber rollers such as photo- 

 graphers use in mounting prints, these costing fifteen cents each. 

 A small bottle of kerosene should also be included in the outfit, as 

 a few drops may be needed to dilute the ink in case it should be a 

 little too thick to spread freely over the slate and roller. The paper 

 used in making the prints should be of good quality, with a smooth 

 surface in order that it may take and hold a fine, clear outline.
