Mr. George F. Becker, of the United States Geological 
Survey, has returned to Washington after an absence of six 
months in South Africa. He visited the diamond mines at 
Kimberley, but spent most of his time near Johannesburg, 
studying the gold deposits. A projected trip through the 
Chartered Company's territory was prevented by the Kaltir

the winter, but probably in England, his data having been 
collected at the expense of English capitalists. — {Science.)
