wheat, and 1,043 pounds of straw. Cost of the fertilizer, $7.50 ; gain in 

 wheat, 3 bushels. 



The professor infers that when the farmer gets back in the first crop 

 the cost of commercial fertilizers, it pays well to use them, " because 

 there is left in the soil insoluble phosphates, lime, sulphur, and organic 

 nitrogen, which will doubtless pay for the fertilizer the second year on 

 most soils," 



P Oats. — Sown on the 18th of December, li pounds of seed, a yellow 

 Georgia variety, with 500 bushels of home-made manure put in at the 

 time of sowing. Product, 29|^ bushels of oats and 1,275 pounds of straw ; 

 cost of production, $14.25 j value of the products, $33.69 j net profit per 

 acre, $19.44. 



Cotton. — With a view to test the effects of organic matter on growth, 

 one flower-pot was filled with river-sand, out of which all soluble matter 

 had been washed ; another with such sand mixed, half and half, with 

 rotten wood, (though not fully decomposed.) The same fertilizer, in 

 equal quantities, was added to both, and a plant of cotton grown in 

 each.. At the date of report, (in August,) that in pure sand, compared 

 with that in sand mixed with rotten wood, was "much smaller and less 

 vigorous, the leaves having a paler and more sickly aspect, with just 

 one-half the number of forms, (6 to 12,) and wilting much sooner from 

 the lack of water." Again, in the autumn of 1873, 200 pounds of green 

 weeds were put in a row 70 yards long, and covered with a turning- 

 shovel ; another 200 pounds were burned, thus dissipating the organic 

 matter, and the ashes covered in a row of the same length. Last spring 

 cotton was planted in both ; at date of reporting that on the weeds had 

 "the appearance of being treated with 200 pounds of a good fertilizer," 

 while that on the ashes of weeds appeared to have received scarcely any 

 benefit from them. 



Wheat-imports of Great Britain. — The following is he officialt 

 statement of the quantities and value of wheat and wheat meal and 

 flour imported into Great Britain for the nine months ending September 

 30, 1874, accompanied by a statement of the total value, and value per 

 hundred- weight, in our currency.
