The substance known as Chili saltpetre, nitrate of soda, and sodium nitrate, NaN0 3 , is a compound of sodium, nitrogen and oxygen.

The substance known as ordinary saltpetre, nitrate of potash, potassium nitrate KN0 3 , is a compound of potassium, nitrogen, and oxygen.

The substance known as ammonia and ammonia gas, NH 3 , is a compound of nitrogen and hydrogen.

Most animal matters contain nitrogen and they also contain hydrogen, as well as other substances; but when these animal matters undergo decay, either in the air or in the soil, they are apt to produce ammonia gas. This kind of change can be understood from the facts already stated; namely, that ammonia gas is composed of nitrogen and hydrogen and that both these elementary substances exist in animal matters.

When ammonia gas is brought in contract with sulphuric acid, a white solid called a salt and more especially designated as sulphate of ammonia or ammonium sulphate (NH 4 ) 2 S0 4 , is formed.

Often animal matters in the soil undergo a process of decay whereby they turn into nitrates. This process is called nitrification.

In case of stable manure the valuable nitrogenous constitutents are chiefly those of urine.

Tankage is a name applied to a dry shred-like material produced in slaughter houses. It is obtained by drying the inferior animal matters, such as entrails, incidental to the slaughtering business. It is rich in nitrogen.

Along the Atlantic coast there are several large establishments using steamers for catching fish for fertilizing purposes. The fish are first boiled in large tanks, Next the oil is skimmed off. Next the semi-liquid, semi-solid, mass is strained and the matter remaining on the strainer is dried. This material consists of the fleshy, muscular parts of the fish as well as the bones. When dried it makes a brittle material rich in phosphates and nitrogen.

Not withstanding the abundance of nitrogen in the atmosphere, its condition is such, and its properties are so peculiar, that it is of extremely small value as a fertilizer. Very few plants can absorb it from the atmosphere. Chemists do not know how to turn it into plant food artificially. The fertilizer manufacturers therefore must have recourse to compounds containing nitrogen, such as animal matters, nitrate of soda, etc.

From what has been said it is plain that ammonia salts, nitrates, animal matters, and indeed other substances containing nitrogen are good fertilizers.

"Takes three-quarters less than other makes." From Fremont Small, Caribou, Me.

About the Chemical Potato Fertilizer I will say I applied it according to the directions and got good results. It has increased my crop one third, all of good size. I am sorry I did not use more on my land than I did, as it would have been a good investment. I shall use the Chemical again next year, as it is cleaner to use, less trouble to apply, much cheaper, and it takes three-quarters less than other makes with better results.
