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...
The mother's first thought, when her daughter finishes
her preparatory work and expresses a desire for

Since this treatise is to deal only with the
construction of one special machine it is unnecessary
to go into an extended discussion of dynamo electric
machinery in general. Some of the parts common to all
electric machinery of this character will be mentioned
and then a short account of...
In long distance transmission where it is impossible to transmit a direct current for electric rail roading and for many other applications on a very low voltage percent line loss, it is essential to transmit the power by means of an alternating current at high pressure and then reduce its...
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

As far back as History goes we have conclusive proof
that man has traded commodities with his fellow-men. At
first these exchanges were in the form of barter, a man
would trade something which he had and did not care much
for,with another man who had something he desired more....
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.
In designing a machine of any kind, considerations
must be made regarding the kind and amount of work
it will be required to do, the foundation for its support,
and the amount of space available for its occupancy.
An engine which is to be used for driving an automobile

conclusion that it is not...
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 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

There is no article of food more commonly used
in all parts of the world than the egg. It can be

"After writing this thesis I have drawn for my
conclusion that cereal breakfast foods as a class
are nutritious, convenient, and reasonably economical
foods and should have a very important place in the diet."--Conclusion
"Salads are not a food of nutriment but are healthful because of mineral salts, which contain cooling and crispness properties--variety they give the diet.
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...
In the educational wave that is sweeping our country from ocean to ocean, technical education is at its crest, and no phase is more popular than domestic science. Indeed it has such a hold upon public opinion that it is quite the fashion, a commendable fact, for as soon as...
Electricity is the name given to an invisible agent known to us only by its attendant phenomena and by various manifestations called electrical. These manifestations, at first obscure and even mysterious, are now well understood. Indeed its great importance to mankind can only be realized when we remember that it...

There is probably no article of diet of animal
origin more commonly eaten in all countries or served

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.
Certain uncooked plants, fruits, nuts, cooked vegetables
and meats seasoned with condiments and dresses
with oils constitute what is known as salads.
The salad plant contains no appreciable amount
of nutriment, yet are, owing to their crispness and
cooling properties, an indispensable portion of the
ideal dinner, and are aids...
It is necessary before placing any piece of apparatus
on the market to thoroughly test it under similar
conditions to that for which it was designed, and to

The study, design, construction, operation and care
or synchronous machines forms one of the most important

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...
If it be true that the meaning of desserts is to

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...
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
