36 ON PLOWS. 



vegetable growth." "To balance the plow and insure 

 a steadiness of movement in the ground, and to resist the 

 pressure of the furrow slice upon the mouldboard, we 

 have added length to the heel of the landside C." "In 

 the construction of Eagle No. 3, designed particularly 

 for sward plowing, we have given it still greater length 

 forward of the standard, which enables us to form the 

 share with an angle still more acute, which form has an 

 advantage in going deep among the small stones, that 

 are usually found in the subsoil, below that which has 

 heretofore been moved by more shallow plowing, and 

 that it may go deep without liability to clog, we have 

 raised the beam two inches higher on the standard. We 

 have also increased the length of the mouldboard, to in- 

 sure the more effectual turning of the furrow; — always 

 taking care that the forward end of the beam shall be, 

 as nearly as possible, in a direct line with the heel of the 

 plow and the point to which the chain is fastened to the 

 yoke of the oxen. Several of these alterations have been 

 made in this plow in the course of the present season, 

 and the use of it encourages the belief that they will be 

 found decided improvements." 



Our attention was particularly called to the quality of 

 the castings on the plows of Ruggles & Co, — their ^w- 

 ish and durability. Their appearance certainly is more 

 perfect than any thing of the kind we have elsewhere 

 seen. Their process of chilling the points, the entire 

 edge of the share, and the Jlcmge or base of the landside, 

 gives a permanence and durability to the work, that ren- 

 ders it of a decidedly superior character. This chilling 

 process has also been applied, to some extent by Proiity 

 & Co. to their points and shares. An examination of 

 several plows that have been used, where this process 

 had been partially applied, has completely demonstrated 

 its great utility. And we think there can be no hazard 

 in saying, that the value of the parts thus made is more 

 than doubled by this process. If due attention is given 

 to the quality of the metal used, and a proper applica- 

 tion made of the chilling process, we doubt not that irons 

 may be made that will last as long as other parts of the
