the white marl. Its agricultural analysis is given on page (12). The next 

 sample is the black vegetable mould itself, found in the same place, from 

 four to twelve inches depth ; it is the soil whose analysis is found on page 

 (9), table I, under No. 1. The ground water in this place is about 18 

 inches below the surface. The last of the three samples is the white 

 marl, the agricultural analysis of which may be seen on page (11), table 

 II, un.ier No. 3. 



The cane in this field absolutely refused to grow in some places, and 

 in others the little cane there was, showed a very stunted growth and a 

 yelJowish appearance. 



No. 10. is situated in "Paja", tablon 3, about 2500 meters from the 

 factory. The cane at this place was not very vigorous, yielding only about 

 20 tons per acre; it was evidently suffering, in spite of the fine 

 composition of the soil itself which has 1.51% of lime, 0.42% of potash, 

 0.17% of phosphoric acid and 0.38% of nitrogen. The surface soil was 

 six inches deep, and the subsoil was sampled to the depth of eighteen 

 inches. 



No. 11 is the Experimental Field near the factory between the two 

 places where samples Nos. 5 & 6 were collected. The cane is quite healthy 

 here, but the yields are not very good. The soil was sampled to the 

 depth of twelve inches, the subsoil from twelve to twenty four inches. 



All the soil samples described were, in the fresh state, analysed 

 for moisture, carbonates, bicarbonates, chlorides and sulfates, and the 

 results .are given in table VIII. None of the samples showed any alkaline 

 carbonates; but they have a slight alkalinity due to the presence of 

 bicarbonates which are, in a strictly chemical sense, acid salts, however 

 salts of a very strong base and a \^ry weak acid, so that the character of 

 the former predominates.
