446 THE YOUNG FARMER'S MANUAL. 



799. Mr. Louis Young has invented an improvement in the 

 measuring wheel, in which there is a neatly graduated circular 

 disk in the end of the handle, which is moved by a pawl, work 

 ing in a ratchet wheel at the disk, which pawl is worked by a 

 cam on the shaft of the measuring-wheel. "When the wheel is 

 rolled forward, the distance traversed over is accurately indicated 

 in feet, inches, and fractions of inches on the disk. But it is too 

 expensive for farmers, otherwise I would have given an illustra 

 tion of it in this place. 



700. For measuring the circumference of small bodies, in the 

 absence of a measuring-wheel, use a piece of small wire, and 

 then take the length of it with the rule afterwards. There is a 

 no more correct way to measure a round body than this. 



701. This chapter on edge tools has been revised and very 

 much abbreviated, and a goodly number of tools which every 

 farmer ought to have, have been excluded in order to bring the 

 chapter within a proper limit for such a work as this. But if the 

 young farmer is possessed of sufficient skill to put these in order, 

 he will be able to put all others in order. When tools of a desired 

 form or kind cannot be obtained at country hardware stores, the 

 young farmer will be able to procure anything which he may de- 

 eire at R. L. Allen's agricultural warehouse, 189 Water st., New 

 York city.
