Married Love - Mutual Adjustment
As things are it is impossible for both sexes to get what they want. One must be sacrificed. And it is better for society that it should be the woman.
Married Love - Sleep
THE healing magic of sleep is known to all. Sleeplessness is a punishment for so many different violations of nature's laws, that it is perhaps one of the most prevalent of humanity's innumerable sufferings.
Modesty and Romance
It is, therefore, not surprising that one of the innumerable sweet impulses of love should be to reveal, each to each, this treasure of living beauty.
One of the most famous instances of the married ascetic is Tolstoy, whose later opinion was that the highest human being completely inhibits his sex-desires and lives a celibate life.
Marriage And Children
Only by the fusion of two can the new human life come into being, and only by creating a new life in this way can we hand on the torch which lights our consciousness in the sphere of matter.
Marriage And Society
Love is fed not by what it takes, but by what it gives, and that excellent dual love of man and wife must be fed also by the love they give to others.
Marriage - The Glorious Unfolding
In love it is not only that the yearning of the bonds of affinity to be satisfied is met by the linking with another, but that out of this union there grows a new and unprecedented creation.
The Tradition And History of Paper Making
Paper, which in convenience and varied utility is as much in advance of its forerunner as papyrus was in advance of brick, stone, lead, copper, brass, leaves, bark, wood and skins, the successive media for the transcription of human thought.
Paper Making - Raw Materials
PAPER has been defined as an aqueous deposit of cellulose, and while this is incomplete as a catalogue of the materials composing a sheet of modern paper, it is an excellent epitome of the foundation of paper making.
Paper Making - Future Fiber Possibilities
At the present rate of increase in consumption, it will require between 15,000,000 and 20,000,000 cords of wood for pulp and paper fiber in 1950.
The Constituents Of Paper
THE technique of paper-making varies greatly in accordance with each particular product..
The Constituents Of Paper - Part 2
Chemical wood-pulps are obtained by a variety of processes, all of which have as their object the isolation of the pure cellulose fiber by the dissolution of non-cellulose components.
Paper Making
The ultimate characteristics of the paper are dependent upon the handling of the beater roll and the character of the knives. For example, a blotting-paper is made by a quick beating with sharp knives.
Paper Making - Part 2
Another feature to be closely watched on particular papers is to eliminate, as far as possible, the impress of the weave of the wire cloth, which is left in the under side of the web.
The Physical And Chemical Aspects Of Paper
THE size and weight of a sheet of paper of any given quality and finish are its most obvious features, and when we speak of the weight of a sheet of paper we refer not to the one sheet.
Appraising And Testing Paper
THE appraisal of a specimen of paper differs from testing in that an appraisal comprehends the value of an object in relation to its usefulness and marketability, whereas testing is merely an arbitrary method of expressing the chemical or physical properties of the object.
Paper - Press Room Difficulties
TECHNICAL difficulties with paper in the press-room arise from many sources. They may be conveniently classified into three groups.
The Paper Trade
The distribution of paper is cared for in part by direct sales from the mills to consumers, such as large publishers of newspapers, magazines, and books, and manufacturers of paper commodities, such as tags, boxes, stationery, toilet accessories etc.
Importance Of A Knowledge Of Printing
THE study of printing should be more general in all our schools-but not as it is taught so often—by teachers incompetent to glimpse and grasp its widest possibilities—to make it live and thrill with all its latent power.
Materials For Records
PROBABLY the first thought that comes to mind when paper is mentioned is that it is a material used for writing or printing; in other words a means for conveying ideas and thoughts.
Non-Woody Fibrous Materials
ALL PAPER is today made of cellulose in one form or another, and in different degrees of purity.
WOOD is, at present, by far the most important source of fiber for paper; it so far exceeds in quantity all other fibers used that it may be said to be the universal raw material for the industry.
THE first producer of groundwood, as well as the first papermaker, was the wasp.
The Soda Process
THE first chemical process for reducing wood to pulp was the soda process, so-named because it uses caustic soda as the cooking agent.
The Sulfite Process
THE second chemical method for pulp making was the sulfite process, invented by Benjamin C. Tilghman, who experimented with the effect of sulfurous acid on wood shortly after the Civil War.
The Sulfate Process
THE third chemical process for the preparation of fibers from wood was developed by Dahl in Germany in 1883. It is an alkaline process similar in many ways to the soda process.
Other Pulping Process
THE three chemical processes and the groundwood process account for the great bulk of papermaking fibers, but there are a number of other methods which are of interest for various reasons.
NONE of the methods used for producing papermaking fibers yields a perfectly pure cellulose or one which is sufficiently lacking in color to make paper of a high degree of whiteness.
Stock Preparation
WITH the exception of papers made chiefly from groundwood, almost all papers are made from fibers which have been given some sort of a mechanical treatment.
The Paper Machine
All paper prior to about 1803 was made by hand on molds which were dipped into the stock to form the sheet.
