I may also mention, as connected with agricultural ma- 
chinery, that a new drill, made at Dunnington, and exhibited 
in York, has been tried on this farm, which drops the manure 
and the seed at every ten inches, instead of sowing them in 
a continuous and useless row. The seed and the manure, as 
they fall from the feeding trough, are stopped by a little trap- 
door or valve, which falls when the wheels have advanced 
ten inches, and then is immediately thrown up and supported 
by a spring until it is again allowed to drop at the advance 
of another ten inches. By this ingenious contrivance no 
inconsiderable saving is made both in seed and manure; 
at least, both are deposited in full quantities where and where 
alone they are wanted. 
It must be unnecessary to show that the good feelings of 
all must be deeply interested in the progress and extension 
of the remaining object of this Society, when I state that 
the third object to which we intend to direct our constant 
attention is the bettering the condition of the work-people 
connected both with mining and agriculture. Here both 
science and skill may best employ the study and the labours 
of the philanthropist ; here we may hope to contribute to the 
health and safety of those employed in our mines and fac- 
tories. Whatever diminishes the risk of life or health in 
any manufacture, or in the exertion of bodily labour, not 
only affords a high satisfaction to the humane consumer, but 
it diminishes also the cost of production, and thus becomes 
every way an object worthy of our best attention. Hence it 
was with pleasure that we listened to Mr. Morton's valuable 
remarks on the safety lamp, and to the suggestions thrown 
out on that occasion by other members, for improvements in 
that most valuable instrument in coal mines, the Davy lamp.
