This table shows that the soils collected were all more or 

 less sandy, .some, however, with a fair proportion of silt, but 

 most containino^ but little clay. The\- are all fine-grained soils, 

 and for all practical i)urposes devoid of ])eb1)les. gravel, and even 

 coarse sand. 



From the above mechanical analyses these soils m 

 classified as follows : — 



be 



Cultivated Soils 

 Virgin Soils 



Sandy 

 Loams. 



Fine Sandy 

 Loams. 



13, 19. 1, 3, 11, 15. 

 18, 20. 2,4,8,12,14,16. 



In this last table, the cultivated soils ha\c been placed imme- 

 diately over the virgin .soils to which they corres])ond. except 

 where the two fall into different classes, in which case the space 

 above (or below) has been left blank. 11ie coarsest scmIs of 

 the .series are Nos. 5, 6, 9 and 10. and these all lie within about 

 four miles from Alexandria, in a south-westerly direction. No. 

 13. a sandy loam of the less fine character, is situated in the 

 .same area. Broadly, the coarser soils incline to grey, and the 

 liner soils to brown in colovu'. 



The most ])ronouncedly brown .soils are Nos. 16, ig, 20, and 

 these all come from farms some 24 miles west of Alexandria 

 village, in the field-cornetcy Congo's Kraal. The most definitely 

 grey soils are Nos. 5, 6 and 7. all of which form part of the 

 area three or four mile- west of .Vlexandria.
