Electromagnetic engines, or motors, are machines in which the motive power is derived from electric currents by means of their electromagnetic action. The following design is for a 1½ K.W. bi-polar motor.
A storage battery is a cell. or a series of cells capable of storing up electric energy and giving it off at a required time. A storage battery acts upon the same principle as a galvanic cell in giving forth electric current as the equivalent of chemical energy, but it...
One of the most important and likewise practical problems that oonfront
the Electrioal Engineers of the present daysis the design and the
construotion of Hydro Electrio Power plants for the generating of electrioal
energy,both for power and li;hting purposes. In order that we
might become better acquainted with the facts...
The rapid advancement of electrical science has led it to invade
the field of marine engineering. On ship-board, all ship's lights,
search lights and signal lights are entirely electric. Of power appliances
outside of uses on men of war,ship's ventilation is completely
electric; electric deck winches and boat cranes are...
In collecting our representative flowering
plants, we have endeavored to secure a specimen of each
common genus of annuals and biennials as well as a few
shrubs. The notes, drawings, and classification of fifty of these plants constitute the main part of our thesis. Following are the classifications of various...
Literature is recorded thought or knowledge; the aggregate of books and other publications, in either an unlimited or a limited sense; the collective body of literary productions in general, or within a particular sphere,

By way of preface, a few words may be said regarding the advantages of the revolving field type of machine.
The first in its favor and the chief reason for its
existence, is that by passing the heavy armature current
through permanent stationary contacts and only the small
Micro-organisms are a distinct class of unicellular vegetable organisms placed under the general name of bacteria instead of trying to affix either algae or fungi to this class of living beings. These microorganisms are divided into two classes; pathogenic and non-pathogenic bacteria. The pathogenesis is determined by inoculating a susceptible...
Alfalfa is one of the oldest of cultivated forage plants.
It was cultivated by the Greeks, Romans, Egyptians, and other
nations of the Fast before the beginning of the Christian era.
It is a native of the southern and western portion of Asia. It
was early introduced into Spain and...
Among sea-weeds the kelps include some of the largest, most widely distributed and most important forms considered from an economical standpoint. They are technically classified among the crown algae in the family Laminariaceae, which comprises some twenty-five genera. Kelps occur most abundantly in the colder sea water, but they are...
Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
At the present time only a portion of Corvallis is sewered and a portion of the city still employs the most crude and unhealthful methods of disposal. The district east of Ninth Street, as shown on the map, has an effective system of well constructed sewers, of the combined storm-water...
As young as American Literature is, it has been found necessary to divide it into five periods, namely: First Colonial Period (1620-1689); Second Colonial Period (1689-1763); Revolutionary (1763 -1815); First National Period (1815 -1863). Though by courtesy called Literature, the first attempts at writing by our forefathers cannot properly be...
During the last twenty-five or thirty years the
growth of the fire insurance business of the United
States has been in close correspondence with the increase

at present, instead of not realizing the advantages of
this form of protection against loss, it...
"In conclusion it may be said that kale is almost
a winter maintenance ration for swine, but when fed in
addition with a little grain or skim milk, good growths
will be made. Especially is this true of young pigs as

In the construction of a rifle for sporting or target work
there are several conditions to be met. In the first place the
rifle must be made to balance easily.at all times, whether the magazine

As a nation salad is a dish we do not sufficiently
appreciate; while the French perhaps surpass all other countries
in the number and variety of their salads. Their quick ingenuity
seems to enable them to turn almost everything in nature
that is edible into a tempting salad.
A feasible development for a Hydro-Electric power
plant can be found in the Mary's River. About 9 miles
west of Corvallis, the north fork of the stream affords
an excellent situation for a dam site. The canon of
the north fork at this point is very narrow, and having
In order that the proper motor for a given service
may be chosen it becomes necessary to study and know
the requirements and characteristics of the machine which
may be used for that purpose. When these are known the
selection of that one which is best adapted for the use...
The design and specification of a dwelling house
constitutes the thesis of the student Arvid Anderson
of the class of '08.
This thesis consists of two parts, namely: drawings
and written description or specification. The drawings
and specifications are to be considered as cooperative,
the latter are necessary to express...
One of the most important matters which face the
people of the United States at the present time is the
conservation of the National Forests. It is estimated
that at the present rate of consumption, if there is

In taking up this study of the evolution of the
home, we have considered it not so much as a dwelling place
for a family, but as a structure - first, as a

architecture, tracing the history of home - building...
The word food is a common noun used every day and
by every one. But have you ever thought of its full significance?
Any substance that can support life or help
to support it is food. Plants require food to support
them when growing; they find it in the air...
Laudanum is the commercial name of "Tincture of
Opium", or "Tinctura Opii", as recognized by the United

alkaloid found in opium and to which...
If it be true that the meaning of desserts is to
offer something more exquisite still, then from the
hygienic standpoint, the wisdom of the procedure is

The problem of the economical transmission of
power has long been a serious one to the engineer. Formerly
the power had to be generated on or near the spot
where it was to be used, but now the advance that has
been made in Electrical Engineering has largely done away...

And salads should be served at every luncheon and dinner, the meat salad being served at luncheon or supper, while the lighter in dietetic value with...
Before we can write intelligently concerning
any subject, we must understand exactly what we are
writing about. As the title tells us, this thesis
deals exclusively with the work and incidentally with
the lives of Robert and Elizabeth Barrett Browning, two
notable nineteenth century poets.
Living now in an age where the steam engine in
many localities soon will be a mere relic more than a
useful mechanism with which to convert steam into useful
energy. It is rapidly being replaced by the gas engine
and the electric generator, in which the latter is
