can afford. The basis for correct estimate 

 is cost delivered in the field. 



Storage. One advantage possessed by 

 the limestone is ease of storage. There is no 

 inconvenience or loss. The stone may be 

 ordered at any time of the year when teams 

 are least busy upon other work, and it can be 

 held till wanted. In this way the cost of 

 cartage to the farm may be kept relatively 

 low, and the material is at hand when 

 wanted, regardless of rush of work or delays 

 of railroads. This advantage is partial 

 counterbalance to the cost of freight on the 

 worthless portion of unburned stone. 



Valuing Limestone. The estimates, so 

 far as labor and convenience are concerned, 

 are merely suggestive, and rest upon the 

 presumption that the stone is satisfactorily 

 fine. It has been urged in another chapter 

 that immediate effectiveness is determined 

 by fineness, but as a working basis we 

 assumed that when all the stone would pass 

 through a screen having sixty wires to the 

 inch it would give the desired results. The 

 coarsest portion would not be available at 

 once, but when an application is heavy 

 enough to serve for a year or more, we have 

 enough very fine material in such a grade of
