PROFESSOR ROBERT DEC. WARD
MONTH later than the date originally set for its opening, the first National Exposition of Brazil was officially inaugurated on August 11. Patriotic pride in the gratifying evidence which the exhibits give of Brazilian arts and industries, and of Brazilian progress, is the dominant note everywhere.

THE LATEST CALABRIAN DISASTER

PROFESSOR WM. H. HOBBS
NOW that more reliable accounts have reached us of the terrible disaster to Calabria and Sicily, it is possible to discuss some larger facts which seem to be revealed with clearness. The grand eruption of Etna, the disappearance of the Eolian islands, and other equally improbable rumors, have ceased to be valuable scareheads in the newspapers.

PBOFESSOR WALTER L. FLEMING
WHEN Jefferson Davis was secretary of war he inaugurated an interesting and important experiment for the purpose of determining whether camels could be used for transportation purposes in the United States. Never before or since that decade preceding the Civil War has the government been confronted with such serious problems as were caused by the territorial expansion of the late forties, and of these not the least serious were the difficulties of communication and of transportation on the far western frontiers.

IT is estimated, so says the Scientific American, that 150,000,000 tons of coal are used annually by the railways of the United States, out of which but 7,500,000 tons are used in drawing the trains, while 142,500,000 tons go up the smoke-stack.

DR. ROBERT VAN VLECK ANDERSON
ON one of the early days of May, 1905, three of us—a Japanese friend, my brother and I—were trudging through long avenues of pine trees and crossing the upland border line between the provinces of Hiuga and Osumi in southern Kiushiu and southern Japan.

PROFESSOR LAFAYETTE B. MENDEL
MY interest has lately been aroused in reading a little American monograph published over a hundred years ago as a dissertation submitted for the degree of doctor of medicine to the faculty of the University of Pennsylvania. It is entitled: “An Experimental Inquiry into the Principles of Nutrition and the Digestive Processes,” by John R. Young, of Maryland (submitted June 8, 1803).

DR. L. A. BAUER
WERE I to accuse you of forgetfulness, of shortness of memory, or possessed of that quality apt to prove troublesome to others, though characterized by the oldest of our past presidents, in his delightful “ Reminiscences of an Astronomer,” as a valuable quality—absentmindedness—I dare say you would not be much offended, though possibly a trifle annoyed.
