CORNELL AND SWENSON—GAS ENGINE VALVE SETTING.         47

cated horsepower was 7.27 showing a mechanical efficiency of 69 per
cent. The engine ran steadily at 80 revolutions per minute, with a
pressure of 110 lbs. on the scale, the brake arm being three feet.

This is the minimum efiiciency. As it was impossible to count
the number of explosions, and as the intensity of the explosions
varied considerably, the computation was made on the assumption of
an explosion every revolution. The largest diagram on the card was
taken, thus giving the largest possible indicated horse power, and the
minimum efficiency.    The real efficiency is much greater than this.

Our experience is an illustration of one of the many uses to
which the indicator may be put, and is unique in that so far as we
know, the indicator has never before been applied in this manner.

The results of our experiments seem to show that with positive
ignition the engine should show a horse power greater than its
rating, which is 10, while running at normal speed, which is about
130 revolutions per minute.
 

THE ARCHITECTURAL SCHOOLS OF THE UNITED STATES.
 

By Edward C. Earl, '94, Architectural Course.
 

The most important schools in the United States which have
departments of architecture are the Massachusetts Institute of Tech¬
nology, the University of Illinois, Cornell University, and the School
of Mines of Columbia College. Other schools giving instruction in
Architecture are: University of Pennsylvania (Philadelphia^, Uni¬
versity of Minnesota (Minneapolis), Case School of Applied Science
(Cleveland), Art Institute of Chicago, Pratt Institute (Brooklyn),
Brooklyn Institute (Brooklyn), Cooper Union (New York), and The
Metropolitan Museum of Art (New York), besides several private
schools.

Massachusetts Institute op Technology.

The Massachusetts Institute of Technology was granted a char¬
ter by the legislature in 1861; the architectural department was es¬
tablished five years later, though there were no regular graduates
until 1873. Wm. R. Ware, an architect of Boston, and a former
pupil of Mr. Hunt, was given charge of the department and con¬
tinued at its head until he was called, to the Columbia School of
Mines in 188L The present high standing of the school is largely
due to his efforts.    W. P. P. Longfellow and T. M. Clark, succeeded
