Dr. Thomson proposes to eall this group of 
limestone caves by the name of Lord Kin- 
naird, in gratitude for the kindness shown to 
him and his brother during their college days. 
He refers also to various other groups of 
caves in the same province, which make of 
this part of China a veritable cave country. 
Though they have been described by Dr. 
Henry in his book ealled “ Ling Nam,” they 
are far from being generally known. They 
include the “ Cathedral cave” (so named by 
Dr. Noyes, of Canton) and others to the 
north of that city on the Lien-chow and North 
and those in the neighborhood of 
Shiu-hing on the north bank of the main Si- 
kiang or West River.

ing at 8:30 P.M.

take place at that institution on April 19 and 
20. Dr. Hermon C. Bumpus, business manager 
of the university, formerly director of the 
American Museum of Natural History, and 
Professors Stephen W. Gilman, of the course 
in commerce, C. K. Leith, of the geology 
department, and K. L. Hatch, of the col- 
lege of agriculture, will comprise the faculty 
committee that will cooperate with 300 senior 
students in preparing for this exhibition. The 
engineering school will be represented by over 
50 mechanical devices shown by its various 
departments. Among the interesting exhibits 
of the college of agriculture will be a model 
dairy and a model barn. Regular milking 
time will be announced so that visitors to the 
exposition can see mechanical milking ma- 
chines in operation. The university bacterio- 
logical department will have an exhibit show- 
ing how many germs are afloat in the air of 
Madison, Milwaukee and Chicago. Plates will 
be put on the street corners in these cities for 
ten minutes and then will be put on exhibition 
to show the vast number of germs present in 
city air. Germs of hydrophobia and tubercu- 
losis will also be on exhibition to be viewed 
through the microscope. How disease is 
transferred by handshaking will be shown by 
having a student with a germ-laden hand 
shake hands with fifty clean hands and then 
show the resulting contamination through the 
microscope. The home economics department 
of the university will be represented in the 
exhibition by a booth showing how to design 
and fit dresses and how to distinguish between 
good and bad taste in house decoration and 
furniture selection. 
UNIVERSITY AND EDUCATIONAL NEWS 
Tue Harvard Graduate School of Applied 
Seience has received from an anonymous 
donor a gift for a high-tension electrical labo- 
ratory. It will be built near the Jefferson 
Physical Laboratory. It is expected that the 
laboratory will have at its disposal an alter- 
nating current of 1,000,000 volts and a direct 
current of 100,000 volts.
