All of these samples contained an abundance of lime, largely in the 

 form of calcium carbonate : they are all well supplied with potash, but tihe 

 proportion of phosphoric oxide varies considerably, ranging from the ex- 

 treme of poverty, in one case, to a fairly satisfactory amount in 1 others.

The three samples enumerated in the above list were taken from the 

 area proposed to be brought under irrigation in connection with the 

 Douglas irrigation works. The first sample was taken from the farm Back- 

 house, near the main canal, at chainage 4 miles 30 chains. No. 2 was col- 

 lected on Douglas Commonage from the middle of Agricultural Erf No. 5, 

 and is fairly representative of all the erven lying along the river bank. 

 No. 3 was taken from Agricultural Erf No. 36, also on the commonage, 

 near the main canal, at chainage 6 miles 10 chains, and may be considered 

 as a type of the erven along the route of the canal. 



In every case the samples represent virgin soils, and were carefully col- 

 lected so as to typify the surface soil to a depth of twelve inches. They were 

 each analysed according to Method I. and also by Method V., and the re- 

 sults of these analyses are tabulated below. *

also includes carbon dioxide combined as calcium carbonate.
