Group 1665. Good growth. The sodium sulphate in A (0' • ~ 0' • 5) 

 is -103 per cent and judging from the appearance of the crop, this 

 amount in the surface six inches does not distress the crop. The 

 concentration increases in the lower depths until in sample D 

 (3'-0 — 5'-0) it is very heavy. 



Group 1664. The results of analysis of this group show fairly 

 heavy impregnation in all samples, increasing from approximately 

 0-5 per cent to 1 per cent in D (3'-0 — 5'-0). The crop was poor and 

 distressed, probably not worth cutting. It was evident that the 

 limits of tolerance had been passed. It is to be noted that marked 

 percentages of magnesium sulphate occur throughout. 



Group 1663. No growth. Alkali showing on the surface. The 

 percentage of sodium sulphate throughout ranges from 1 to 2 per cent, 

 the latter occurring in the surface 6 inches. This impregnation is too 

 high to permit of any growth. 



Western Rye Grasses 

 Series VIII, Section 2, Township 24, Range 25, West of the 4th 

 Meridian. 



On July 20th, 1918, three groups were taken from a field of Western 

 Rye grass, one mile south of Strathmore, Alberta. The area had been 

 under irrigation for a number of years. Water table from four to five 

 feet, according to contour of land. Soil a very dark brown or black 

 sandy loam of good quality, sub-soil of clay loam to clay, with some 

 sand and gravel. Foxtail growing on the bare alkali spot. The crop 

 was good on better part of the field.
