owing to the uneveiiiiess of the soil the latter level was measured from 

 the lowest point of the surface. On removal the soil was placed in a linen 

 bag. 



The small plate was then replaced and driven down another two 

 inches, and the hole in the path was deepened by about another two 

 inches (Fig. 3). The soil in the box was then removed in the same way 

 as before. The second and succeeding samples were taken at depths of 

 two inches at a time, each being placed in a separate bag. 



The soil was removed in this way to a depth of nine inches, giving 

 five samples, which consisted of — I, the soil between the surface and a 

 depth of one inch below the lowest point of the surface; II, the soil

between a depth of one inch below the lowest point of the surface and 

 a depth of three inches; III, the soil between three inches and five inches; 

 IV, the soil between five inches and seven inches; V, the soil between 

 seven inches and nine inches. 



The samples obtained in this way were taken to the laboratory for 

 examination. When the soil was wet it was necessary to spread it out 

 to dry for some time, before it was possible to examine it thoroughly. 

 The examination had to be carried out by crumbling the soil on to sheets 

 of brown paper, and watching for the appearance of insects, etc., as the 

 soil was broken up. The soil was examined over brown paper instead 

 of white, which at first might seem more suitable, because the most
