No. 15. Cultivated buriace soil, very similar in colour and texture to No. 13. 

 The nitrogen and organic matter are somewhat lower than those of the virgin 

 soil. In phosphoric acid it is deficient. 



No. 16. A loam from Mr. Hiram Walker, Walkervile. A fair soil in com- 

 position, with the exception of phosphoric acid, which is low, and of lime in which 

 it is particularly deficient. 



No. 17. From J. N. Poirier, Victoriavillo, Arthabaska County, P.Q. A sandy 

 loam of fair quality, but rather low in mineral constituents. 



No. 18. Subsoil to the above and very similar to it is the proportion of potash 

 and phosphoric acid. For a subsoil it may be considered high in nitrogen. 



No. 19. Also sent by Mr. Poirier. It is a black muck of average quality. As a 

 soil it contains an abundance of nitrogen, though this is only slowly rendered 

 assimilable, and a fair amount of phosphoric acid. In potash it is remarkably 

 deficient. The best fertilizer to improve the composition of this soil is wood ashes, 

 which contain from 4 per cent to 9 per cent of potash and about 2 per cent of phos- 

 phoric acid ; leached ashes are very much poorer in potash. An application of from 

 60 bushels to 150 bushels to the acre of fresh ashes, according to the nature of the 

 crop about to be grown, would give good results. The texture of this soil would 

 be benefited by a heavy dressing of clay, sand or other inert matter. 



No. 20. Subsoil, underlying the above. A greyish sandy soil, containing little 

 potash, but fairly rich in nitrogen. Though not contributing much plant food, its 

 admixture with the surface soil (No. 19) would very materially improve the latter 

 by rendering it heavier. 



No. 21. A pinkish red sand, containing very little organic matter and only 

 traces of nitrogen. The amounts of the mineral constituents, including potash and 

 phosphoric acid, are very small. 



No. 22. A brownish red, sandy soil, considerably richer in organic matter and 

 nitrogen than the preceding sample. It is rich in potash, though phosiDhorio 

 acid is present only in small quantities. 



Nos. 21 and 22 were from St. Adelaide de Pabos, P.Q., and were forwarded by 

 the Rev. Joseph Dechamplain. 



No. 23. A surface soil from the farm of A. S. Ross, Hansford, Cumberland 

 County, N.S. A brown, sandy soil, very poor in nitrogen and phosphoric acid. 



No. 24. Sent by John Grillis, South-west Mabou, N. S. A brown, sandy soil, 

 having a fair amount of organic matter and nitrogen. It is comparatively high in 

 potash and low in phoophoric acid. Lime is practically abseut.
