Regarding the Essay as embracing and explaining all that it is important for us to know, relative to the principle of the action of manure on the soil, I need only say that the ideas of Prof. Stephens and my own entirely agree with respect to the relative value of barnyard manure. I have been using that for years, at the rate of 40 loads to the acre, and it answers every purpose. I have pursued a regular rotation of garden crops, and cropped heavily, and my productions have been seen by many of my friends here. I commence with potatoes and cabbages, and continue some crops requiring no special application of manure. I have also employed concentrated manures with immediate and good effects.

Dr. George Pepper Norris desired to offer a few words, having had some little experience in the application of manures. While he concurred in the opinion that barn-yard manure was one of the best materials where available and not too expensive, he could recommend night soil as much more advantageous in some instances. This might be procured in the vicinity of any town; and although many persons were afraid of the crops being burned by its application, fresh from the cellars, he had proved such fears to be groundless. He applied it from the cart fresh from the cellar, and raised early and vigorous crops. His experience was principally in truck farming, as pursued on the Neck, and his soil sandy, in the vicinity of Wilmington. He was disappointed not to hear this recommended by the gentleman who had last spoken.

James Jones, in reply to Dr. Norris's remarks, would say, that if he could obtain night soil conveniently, he would use it; one benefit would result. Weeds would not be so plentiful; but he did not fear the weeds; his purpose would be to look out for the crops, and let the weeds look out for themselves.

C. H. Miller thought that the value of night soil had been stated in the Essay.

Had found that stable manure, applied in this way, encouraged the black fly, which devoured ail the crops of turnips and cabbage. By plowing in the manure to a proper depth, it sufficed for two crops, as he found the ground sufficiently rich for two crops in succession, in some instances.
