as this will allow the grease to escape from the box and 

 c unnecessary waste. The shimmin eking in 



the box should be cut so as to touch the journal at both 

 ends of the box, but not in the center or between : 

 two points. So, when the top box is brought down tight. 

 this will form another reservoir for the gre.^r. If the 

 box is not tapped directly in the center for the cup, it will 

 be necessary to cut other grooves from where it is tapped 

 into the grooves already made. A box prepared in this 

 way will require but little attention if you use good 

 grease. 



A HOT BOX 



You will sometimes get a hot box. What is the best 

 remedy? Well, I might name you a dozen, and if I did 

 you would most likely never have one on hand when it 

 was wanted. So I will only give you one, and that is 

 white lead and oil, and I want you to provide yourself 

 with a can of this useful article. And should a journal 

 or box get hot on your hands and refuse to cool with the 

 usual methods, remove the cap, and after mixing a por- 

 tion of the lead with oil, put a heavy coat of it on the 

 journal, put back the cap and your journal will cool off 

 very quickly. Be careful to keep all grit or dust out of 

 your can of lead. Look after this part of it yourself. 

 It is your business.
