40 ON PLOWS. 



lute quantity of soil raised and turned. This peculiarity 

 of a level run, I think belongs to my plows in a greater 

 degree than to others." 



"In 1816, I received a premium at Brighton for an 

 improvement in the structure of my plows, which con- 

 sisted in placing the point of the share on a level with 

 the bottom of the plow; thus obtaining a smooth cut at 

 the bottom of the furrow, and consequently with less 

 friction than those made with the points depressed/' 

 "In 1820 I made my first pattern of a cast iron mould 

 board and landside, retaining the wrought share and 

 cutter." "Soon after, however, 1 made a sett of pat- 

 terns for castings embracing the share also. These I 

 believe were the first plow patterns made in Massachu- 

 setts. Since that period I have made such improvements 

 as experience suggested, and have I think arrived some- 

 what near the objects desired in the use of the plow, viz: 

 thorough work, easy draught, easy guidance, and dura- 

 bility of structure." "In order to obtain these requi- 

 sites I place the share so that it shall run level, which 

 gives an equal depth of cut, both on the land side and at 

 the righl angle point of the share. I thus give such a 

 turn or curve to the mould board as shall raise and turn 

 the furrow without pressing it forward." 



*'The "centre draft" of a plow is proved by the pow- 

 er applied for its guidance; and the plow that has a 

 perfect "centre draft" would require no guidance at 

 the handles, in a soil of equal resistance, provided the 

 draft was applied in a strait line with the furrow." 



Our personal acquaintance with Howard's plows has 

 been less than with those of either of the others — but 

 judging from the specimens exhibited, we think their 

 workmanship and their character for durability quite 

 equal to either of the others. We know that they are 

 preferred by some practical farmers, particularly in old 

 ground. Of this we are certain, both from Mr. Howard's 

 manner o{ luorking and loriting that he is a master of his 

 business. 



Mr. Winslow's plows were made in the form of those 

 introduced a few years since by Mr. Pike of Danvers,
