CARROTS, MANGOLDS AND SUGAR BEETS. II 



Dr. Voelcker gives the result of 10 analyses of the 

 ashes of the root and 2 of the ashes of the leaves of the 

 Carrot, ancj from these deduces the following as the num- 

 ber of pounds of mineral matter taken from an acre of land, 

 by 10 tons of roots and 4 tons of tops. 



Potash, Soda, Lime, Phosphoric Acid, 



1 16 lbs 86 lbs. 101 lbs. 31 lbs. 



Sulphuric Acid, Chlorine, 



34 lbs. 31 lbs. 



To those who desire to experiment with mineral manures 

 this table will be interesting as showing the kinds and propor- 

 tion of each needed. The potash is found iif unleeched ashes, 

 at the rate of 4 or 5 pounds to the bushel ; or in the German 

 Potash salts ; the soda and chlorine in common salt, (chlo- 

 ride of sodium) ; lime in the common lime of the mason, 

 the Phosphoric acid in the phosphates offered in the markets, 

 and the Sulphuric acid in that directly or in common finely 

 ground plaster, known by chemists as Sulphate of Lime. 



I shall have occasion to present some very valuable sug- 

 gestions of the learned Professor, under the head of "The 

 Manure" in my article on Mangolds, to which they more es- 

 pecially apply. 



The greatest single item in the cost of any crop is 

 the manure, but this is an exceedingly varying element. 

 Farmers near cities, and particularly if they also reside 

 near the sea-coast, as an off-set for the greater cost of farm- 

 ing-land and expenses of living, have the advantages of a city 

 market and special facilities for collecting manures, at a cost 

 to them, much below the standard value of stable manure. 

 Night soil to- almost an unlimited extent, can be obtained for 

 the cost of collecting it, while the waste material of the fish- 

 eries, Kelp, Rock Weed, Muscle Mud, Glue Waste, Sugar 

 House Waste, and the products of the distilleries, these and
