title " Yorkshire," there would be no difficulty in meeting 
the other Society at Hull next year. He hoped that by union 
of purpose, they would effect most important improvements 
in the art of cultivation. He quite agreed in the observations 
of Mr. Thorp as to the importance of sub-soil ploughing, 
and although it had not been tried successfully in this country, 
there could be no doubt, from what had been experienced in 
Scotland, that it was of immense advantage. He also quite

question. Mr. Thorp had recommended straw-yard manure. 
Would he recommend it to be applied in a fresh state, or in 
a state of decomposition ? Next, with regard to the preser- 
vation of liquid manure in tanks, a plan recommended by
