CONTRIBUTION TO THE STUDY OF THE GRASSES OF 

 ANGOLA. 



The author presents this work as the first of a series of 

 studies on the feeding of animals in the Portuguese Colonies, 

 which he proposes to make in the laboratories of the Higher 

 Institute of Agriculture at Lisbon. 



He begins by defining the local word capim (hay), and 

 considers this fodder as the basis for the feeding of cattle in 

 Angola. Then he sketches the still rudimentary state of 

 zootechnical exploitation in this Province, and maintains 

 that it will constitute an incontestable source of public wealth 

 if the colonists will give their best attention to it. 



Considering that the first step in any exploitation of this kind 

 should aim at the production of good fodder, which constitutes 

 the raw material to be transformed by the animal machine, 

 he condemns the custom of abandoning the native animals to 

 the pasturage of the natural prairies without making any 

 attempt up to the present to establish artificial pastures. He 

 then studies three samples of hay (capim) from different 

 localities in Angola. 



He precedes this study with some general considerations 

 on the diversity of the climate and flora. He attempts 

 the botanical study of the samples sent, in which he succeeds 

 in classifying some plants, and then on the basis of the opinion 

 of several authors (in the absence of local flora) he forecasts 

 the botanical composition of the natural fodders. 



He then examines the value of the samples in question, 

 beginning with a brief macroscopic study, in which he employs 

 Dechambre's method of " points." After this he describes 

 his chemical examination, comparing the quality with that of 

 Portuguese and foreign hays.
