and, in many cases, fertilization of the soil, are generally necessary for 

 obtaining a moderate crop ; cattle must be protected from the parasites 

 and diseases which carry them off wholesale; the planters must make 

 many experiments to find suitable trees and then discover a market for 

 his fruits; gold digging can only be made to pay by companies with 

 large financial resources employing the most modern scientific methods 

 for the extraction of the metal; and the trader is handicapped by the 

 cost of transportation and the small demand for his goods. These are 

 some of the problems which the colonist asks his visitors with their 

 store of knowledge to help him to solve : he needs every device which 

 science can furnish to enable him to exist. Further, his land has been

lately rent by civil war, and two white races with totally 'different 

 ideals must live side by side working together for the common good : 

 the black races, far outnumbering the settlers, present problems at 

 least as difficult as those we have to deal with in the United States. 

 He asks too for help in building up schemes of education for both 

 black and white, and these schemes must include primary and secondary 

 schools, colleges and universities for the study of the humanities and 

 • pure science, and, what is perhaps more important than all for the 

 prosperity of the colonies at the present moment, institutions where 

 elementary and advanced technical education in all its branches can be 

 obtained. If any help is forthcoming towards the solution of these 

 questions, South Africa will feel well repaid for her hospitality and 

 will consider that the visit of the British Association to her shores has 

 not been in vain.
