Bullock's blood contains the same in clifferent proportions, and 34.2 of 

 gluten, sheep dung- 33.0 of gluten, goat's dung 32.8, horse dung 14.0, hu- 

 man urine 36.0, pigeon's dung 11.6, cow dung 11.0, vegetables decomposed 

 10.0. 



Ordinary farming land, irrigated with the liquid of a barn yard, with 

 either of the following named substances added to it, will produce as follows; 



Night soil 14 fold. 



Bullock's blood 13 " 



Sheep manure 12 " 



Goat's do 11 " 



Horse do 10 " 



Human urine 14 " 



Pigeon's dung 9 " 



Cow dung, pure 6 " 



Vegetable manure 6 " 



By the addition of wood ashes and sulphated uriue to the liquid, the yield 

 of wheat per acre, would be 42 bushels, yielding pure flour in proportion Ct 

 lbs., gluten 11 percent. 



By the addition of sulphate of soda, the yield of wheat per acre would l>o 

 43 bushels, yielding pure flour in proportion, 65 lbs., gluten 10 per cent. 



By the addition of chloride of sodium, the yield would be 41 bushels, 

 yielding pure flour in proportion, 63 lbs., gluten 9 per cent. 



By the addition of nitrate of soda, the yield would be 40 bushels, yielding 

 pure flour in proportion, 53 lbs., gluten 9| per cent. 



As it is utterly impossible for the agriculturist to understand the laws 

 by which nature's operations are conducted, in the vegetable kingdom, 

 without some knowledge of the elements out uf which all the products of 

 vegetable growth and increase are elaborated, I will name them. They 

 consist of flfty-five elementary bodies, as follows: Sulphur, nitrogen, oiy. 

 gen, hydrogen, iodine, bromine, chlorine, phosphorus, selenium, barium, 

 lithium, sodium, potassium, silicon, boron, carbon, fluorine, strontium, zir- 

 conium, yttrium, glucinium, aluminium, mngnesium, calcium, thorium, cad- 

 mium, zinc, nickel, cobalt, iron, manganese, lanthanium, cerium, silver, 

 mercuryuranium, copper, bismuth, tin, lead, pa ladium, tantalum, titanium, 

 osmium, gold, platinum, iridium, tungsten, arsenic, tellurium, antimony, 

 chromium, vanadium, molydenum, columbium. Some one says that, look- 

 ing back at the vast strides which organic chemistry has made within 

 twent3'-one years, and is still making, aTid trusting to the continued pro- 

 gress of human discovery, that the time when the art of man shall not only 

 acquire a dominion over that principle of life, by the agency of which plants 

 now grow and alone produce food for man^nd beast, but shall be able 

 also, in many cases, to imitate or dispense with the operations of that prin- 

 ciple; and to predict that the time will come when man shall mauufiicture, 

 by art, those necessaries and luxuries for which he is now wholly depend- 

 ent on the vegetable kingdom. 



Having conquered the winds and the waves by the agency of steam, is 

 man really destined to gain a victory over the uncertain season, too ? Shall 

 he come, at last, to tread the soil beneath his feet, as a useless thing — to 

 disregard the genial shower — to despise the influence of the balmy dew — 

 to be indifferent alike to rain and drought, cloud and sunshine — to laugh
