tlic first premium of the New England Agricultural Society, at 

 Providence, in 1867, as a just recognition of its quality as a 

 plow for general work. 



The series of plows known as the Deep Tiller, {fig 26,) 

 now manufactured by the Ames Plow Company, of Boston, is 

 designed to embrace a variety of sizes and forms of the mould- 

 board, adapted to every kind of soil and peculiarity of a varied 

 agriculture. 



The mould board is formed by a series of straight lines, hori- 

 zontally or in the direction of the movement of the furrow 

 slice, but admits of all the variations required to produce a 

 longer or a shorter mould-board, of a gentler or a more abrupt 

 curvature, with straight or more or less concave lines laterally, 

 as different soils or practices may demand. The mould-boards 

 have a combination of curved lines and planes, having aia equal 

 bearing upon the furrow slice, and receiving an even polish 

 upon their entire face, giving the furrow slice an equal and 

 complete twist in turning over, laying it in the desired position, 

 and in a mellow and disintegrated condition for the reception 

 of the harrow. 



For stubble land and stiff soils the same firm manufacture 

 what is known as the " Telegraph No. 3," {Jig. 27,) which is 

 considered an improvement upon the Deep Tiller, in the form 

 of the standard mould-board, and in securing the beam to the 

 plow by a clasp instead of a bolt. This plow cuts a furrow 

 from twelve to fourteen inches wide and eight inches deep, lay- 

 ing it flat and smooth. Both these plows received the highest 

 premium of the New England Agricultural Society at the trial 

 of plows at Amherst, in May, 1868, as the best in their re- 

 spective classes. 



Another form of mould-board is found in Allen's "Cylinder 

 Plow." {Fig. 28.)
