that portion of South America. Two hundred leagues square 
of rubber trees have been opened to commerce, where each 
square league will contain from three hundred to five 
thousand trees. This will furnish work to large numbers of 
men ten months in the year, each man being able to collecSt 
from 10 to 25 pounds of rubber daily. It shortens the route 
of transportation of the products of the Lower Beni from 
700 miles to less than 300, and necessitates the passage of 
only one fall in the river instead of five falls. For the larger 
portion of Bolivian commerce it obviates the toilsome tran- 
sit over the Andes, and the long voyage around Cape Horn 
or through the Straits of Magellan,

to that of their passing : he will therefore devote special 
attention to those who are most likely to pass, — to those who 
have, he finds, the best verbal memories. We will now give 
extracts from the reports of the Department’s own ex- 
aminers as proof of the correctness of this statement. But 
before giving the extracts, I will give a question and answer 
taken from the Report of the SeleCt Committee on Schools 
of Art, published in 1864, on this subject. Mr. Edmund 
Potter, a member of the Committee, tendered himself for 
examination. Amongst other questions asked him, several 
related to what he would consider the best mode of paying 
teachers in the Department’s schools in order to secure the 
best instruction. He recommended that the teachers should 
be paid by salary. He thus expressed himself as to the 
payment on result system. The question asked— “ Do you 
prefer that system (payment by salary) to the system of
