Improved Dibbling- Wheel. 



Ours having two wheels working upon two ridges (21 inches apart), the 

 man naturally walks in the furrow between them ; and, with a very 

 little practice, can use two wheels as easily as one, and of course work 

 two ridges at the same time. 



We sow from 3 to 4 lbs. of seed per acre, which enables us to deposit 

 from two to four seeds in each hole, and which of course gives a better 

 chance of a plant than only one. 



I can only add our entire concurrence in this mode of sowing that 

 very useful root above any other we have yet seen tried. 



I am, Sir, 



Your obedient servant, 



William Adams, Jun. 

 Great Barton., Bury St. Edmunds, 

 April 15, 1842. 



[It might be an improvement in this implement to set the dib of one wheel opposite to the 

 centre of the interval in the other wheel.] 



[The Dibs are 2 inches long by \\ inch wide at the base, and tapering to a point ; 

 and can be set 14i in., 16^ in., and 18^ in. apart.] 



III. — On the Application of different Manures as a Substitute 

 for Bones in the Growth of Turnips. 



To Henry Hand ley., Esq. 



Sir, — The very high and increasing price of bones having induced me 

 to endeavour to discover a substitute, I send you the result of some ex- 

 periments made under my own superintendance this season. Soil, a 

 sandy loam, varying from 9 to 12 inches deep, recumbent on a lime- 

 stone bottom.
