Water is one of the primary wants of
human life no less essential than air and food hence
the strong and religious interest that has been
attached to the means of its supply. In the earliest
records of civilization we read of the digging of

The financial success or failure of a lighting or power
enterprise is measured by the efficiency of the machinery,
and the efficiency of the machinery depends upon
that of each piece of apparatus of which it is composed.
In alternating current distribution the transformers are

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

It has been a standing problem among the scientists of the past and will perhaps be puzzled-over for many centuries to come; namely the most efficient method of transmitting power from one point to another. The nearest solution at present, and a very satisfactory one, is electricity. By means of...
The study, design, construction, operation and care
or synchronous machines forms one of the most important
branches of electrical engineering. The extent to which
they are now being used is a notable feature of recent
electric progress.
The term synchronous machines covers quite a field

As far back as History goes we have conclusive proof
that man has traded commodities with his fellow-men. At

Only within the last few years have literary critics
come to recognize in the short story a definite type,

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...
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...
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.
This thesis is mainly a collection of historic data regarding the Union Pacific Railroad together with the opinions of various persons regarding the Union Pacific; also opinions on corporations in general and railway corporations in particular.
A mineral map is often of considerable value to
those interested in miring work and development. Since
there are very few, if any such maps for Oregon, we have
endeavored to cover the ground, though only in an incomplete way, since the time we had for working upon it was...
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.
Slowly and half-heartedly the people of America have come to atone for past neglect of a poet who, under painful circumstances, produced the most distinctive and original contributions to American literature. They realize that the follies of his unfortunate life can be put aside and the weight of criticisms let...

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...
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...
Probably no other process of such importance is so
