605. We are unable to meet with a perfect organic analysis 

 of either the plant or seed, but the following results of 44 

 analyses by Way, Nesbit, and Lawes, of English, American 

 and Dutch Linseed, will give an idea of the composition : 

 Water, 7.6 to 12.4 percent, 

 Organic matter, 81.0 to 84.1 &quot; 

 Ash, 5.44 to 11.40 

 Nitrogen, - - 4.57 to 5.28 &quot; 

 Albumen, gluten, and casein, 22.2 &quot; 

 Fat or oil, - 9.1 to 13.5 &quot; 

 Gum, dextrine, &c., - 36.3 to 39.1 &quot; 

 Fibre and Husk, 9.5 to 12.7 &quot; 



606. The following recipes are given as special manures to 

 return to the soil what is carried of by the seed (A ;) and stem 

 (B,) of Flax. (Johnston.) 



A. B. 



Bone dust, . 144 Ibs, 50 Ibs. 



Sulphuric acid, 72 &quot; 25 &quot; 



Carbonate of potash (dry,) - 36 &quot; 17 &quot; 



Carbonate of soda, (dry,) 6 &quot; 20 &quot; 



Carbonate of magnesia, - 22 &quot; 21 &quot; 



280 Ibs. 133 Ibs. 



Linseed leaves (on an average) 6 1-2 per cent of ash, so that for every 

 100 Ibs. of linseed harvested, 13 Ibs. of the above mixture require to be 

 added to the land. The dry stem leaves 5 per cent of ash ; every ton 

 therefore carries off the land 112 Ibs. of inorganic matter, to replace 

 which 150 Ibs., of the above mixture must be added. If this be care 

 fully done, and if the fermented scutchings be returned to the land, the 

 culture of flax will cease to be exhausting. The flax-fibre is almost 

 pure Liguin.
