HOLBROOK'S PATENT SWIVEL PLOUGHS. 



FOB LE^TEL I/AND AND SIDE-HILL PLOUGHTNG. 



Since the introduction of the Mower and 

 Reaper, it has been found very desirable to 

 avoid the dead furroivs and ridges left by the 

 common ploughs, and lay the fields down level 

 for mowing. The Side-hill or Swivel Ploughs 

 heretofore made have been resorted to for 

 level land ploughing, but they turn an imper- 

 fect furrows and clog in sticky soils. 



Holbrookes new series of Swivel Ploughs 

 are convex and elliptical in form of mould- 

 board, and crack, disintegrate and pulverize 

 the soil very thoroughly, and will not clog. 

 They turn a deep, ^a^/'«?'roMJ on level land, 

 as perfectly as the best Level Land Ploughs, 

 and work well on hill-sides. The team per- 

 forms its day's work easier than with the com- 

 mon or Level Land Plough, as in going the 

 off ox or horse travels in the furrow, and in 

 returning the near one walks in the furrow, 

 and consequently both are relieved by the 

 change. 



These ploughs are furnished with wood or 

 iron beams, as purchasers may prefer. The 

 following sizes are made, viz : No. 0, a small 

 one-horse plough; No. 1, a large one-horse 

 plough ; No. 3, a small two-horse plough ; No. 

 6 and No. 6, each a two-horse or cattle plough ; 

 No. 7, for three horses or cattle ; No. 9, for 

 four cattle, and deep heavy work. 



F. F. Holbrook & Small, 10 South Market 

 Street, opposite Quincy Market, in this city, 

 are the manufactnrers. 



For the New England Farmer, 

 FLOUR OF BONE. 



Having seen a variety of conflicting results, 

 reported in your paper, from the application 

 of "Flour of Bone," I propose to add my 

 quota of expeiiience in regard to its effect. 

 Having an acre of ground that had produced a 

 fair crop of corn the previous year, and which 

 I wished to sow with barley and seed to grass, 

 I staked the whole off in strips, and marked 

 them. Applied flour of bone to one division; 

 lime to No. 2 ; and left No. 3 without any fer- 

 tilizer, and sowed phosphate upon the remain- 

 der. Nos. 1, 2, and 3, appeared just alike, 

 while the barley was growing ; but that por- 

 tion that received the phosphate was so much 

 darker in color, thicker, taller and heavier, 

 tliat the difference could be seen at the distance 

 of at least one-fourth of a mile. The bone 

 and phosphate were applied at the rate of 500 



f)ounds per acre. So far, I was not particu- 

 arly astonished at the result, as previous ex- 

 periments had led me to expect that phosphate 

 acted rapidly, while the effect of hone was 

 slower in manifesting itself. I didn't write to 

 the Fakmer, and condemn the bone, but wait- 

 ed. About three weeks after the barley was 

 harvested, the strip that held the bone, showed 

 a far thicker and greener start of young clover 

 than the rest of the field, and thus it went into 

 winter quarters. Last spring the bone was
