"Before a company which manufactures electrical
machines allow them to leave the factory, each must
undergo certain tests to make sure that there are no
faults of design or workmanship and also ofttimes that they meet the specifications of the buyer. Four important
tests are made, e.g. (1) no load...
This thesis comprises a series of tests run on a compound direct current generator and an induction motor; separately and combined as a set, with sheets of data; characteristic and efficiency curves and deduction drawn therefrom relative to the two machines.
Only within the last few years have literary critics
come to recognize in the short story a definite type,
one having its own individual characteristics and limitations.
It differs from the novel in a brevity not
merely accidental which prohibits the too extensive development of the three elements of the...
Throughout history, the supply of foods necessary to
bodily sustenance has been an engrossing if not altogether
profitable occupation. Exception may be taken to the
use of this term, but when we consider the number of laboring families whose first and greatest aim is to meet the
call of the...
Before discussing the American press of the day,
with its freedom and power, a brief historical review
of the development of journalism in its several functions
seems in place.
American Literature, previous to the Civil War, is
of necessity confined closely to the writers and writings
of New England and New York. At present however a gradual widening of the literary field may be clearly discernible. The South and West now contribute their share,
and no one can truly...
The purpose of this thesis is the determination of the load characteristics of the Steam-Hyciro-Electric Plant owned and operated by the Lebanon Electric Power and Water Co. This corporation furnishes electrical energy for power and lighting service and also the water supply to the city of Lebanon, Oregon.
"The literature that has been produced in the
South springs from the depth and fullness of the southern nature; it is all picturesque, in one manner or an
other. Creative art is everywhere evident, especially
in the works of Edgar Allan Poe. The works of George
Washington Cable receive vitality...
Much has been accomplished in the last few years
toward the conservation of natural resources, and in
this work the engineer has taken a leading part. The
prevention of unnecessary waste, the utilization of
hitherto useless by-products, and the economic production of the world's necessities are important features of this...
During the past year the rapid increase in the cost of copper and aluminum has led operating companies to investigate the feasibility of using iron and steel conductors for transmission and distribution purposes where small blocks of power are to be served. This Thesis gives the results of tests on...
The question of whether to purchase power or to
maintain an isolated plant is one which frequently
confronts the engineer, and the problem is by no means
easy of solution, as there are a number of factors
which vary with individual cases and determine the
economy and desirability of the...
Probably no other process of such importance is so
little understood as that which takes place within our
own bodies. We know that we drink water and are refreshed, eat a meal and are strengthened, that the food
we consume is in some way converted into living tissue;
but the...
The most interesting study connected with the
development of the American novel is the accompanying
feature of the growth of the country itself. In a
certain way the changes seem peculiar, but in another
way they are exactly what we might be led to expect.
In tracing the development from...
The marked movement of utilizing Oregon's water power
in the service of generating electric current, has been promoted
by the economics in transmission of electricity to distances
both great and small; by the harnessing of industrial
implements to electric power; and by the advancement and extension
of interurban railways.
It...

During the last five years the demand for electrical
energy in the state of Oregon,and throughout the entire
country,has increased to such an extent that electrical
generating stations have become an important factor in the
economic development of the common wealth.
Uonsidering the great need for cheap power, which
is...
The induction motor in its electromagnetic features
is essentially a transformer, while in its general behavior
it is analogous to the continuous-current shunt wound
motor. In a transformer the primary and secondary members
are both stationary and electrical energy is transformed
from one pressure to another by the ratio of...
Prepared and unprepared food may be compared with civilized and uncivilized man. The latter takes his nourishment as it is offered by nature; the former prepares his food before eating, and in ways that are agreeable and pleasing to the taste. Some of the ways in vvhich meats were prepared...
All living things require food but none make use of
such a variety of foods as does the human race. Many
half civilized people of the earth live on very coarse
materials. The American Indians, for example, do not use
a great variety of foods such as we do, but...
As the atmosphere, the general bustle and rush in our busy eastern cities is vastly different from our quiet and peaceful west, so is there a great difference in the themes and styles of eastern and western authors. The influence of pioneer life and of western scenery, of climatic conditions...
The women of the past ages have made little progress
in literature, and many are those who have ascribed
it to lack of talent which is evident in the gentler sex;
but more agree with Eliza V. Farnham when she says, "I
will yield to none in the grateful admiration...
"In his style Hawthorne early developed that maturity
of dignified composure, free from constraint or affectation,
and that lucid expression, which are among
its most characteristic traits. With little faculties
for the harmony of verse he had a singular command over
the musical qualities of prose, enabling him to produce...
"A woman inherits capabilities of becoming such an
helpmeet, but she stands sadly in need of training for
the development of these capacities and for the acquirement of skill in doing these tasks after she realizes her ability. Education does not consist of facts

Samples of insulating materials used in the construction
of electrical machinery and apparatus are
tested for dielectric strength before such are accepted
for use. This is done by applying to the sample a
high voltage until it is pierced through by the electric
spark. This is a parallel case to...
The designing of electrical machinery is fully
as essential to the thorough understanding of power
equipment and apparatus, as is the taking of a laboratory
testing course. One learns the relationship
of the different parts, the methods of computing
their dimensions, and the predetermination of outputs,
efficiencies, etc. and thus...
It is only recently that Cookery has been looked upon as a science of vital importance. At present the majority of the people fail to realize the vast importance it bears to the happiness and welfare of humanity and it is becoming further established every year. Oregon is retarded in...
Confections are recognized by every man, woman and
child of almost all of the civilized nations of the
