The combatants, who make bull-fighting their profession, march into the arena in procession. They are of various kinds--the _picadores_, combatants on horseback, in the old Spanish knightly garb; the _chulos_ and _banderilleros_, combatants on foot, in gay dresses, with colored cloaks or banners; and finally, the _matador_ (the killer).
As soon as the signal is given the bull is let into the arena. The _picadores_, who have stationed themselves near him, commence the attack with their lances, and the bull is thus goaded to fury. Sometimes a horse is wounded or killed (only old, worthless animals are thus employed), and the rider is obliged to run for his life. The _chulos_ a.s.sist the hors.e.m.e.n by drawing the attention of the bull with their cloaks; and in case of danger they save themselves by leaping over the wooden fence which surrounds the arena. The _banderilleros_ then come into play. They try to fasten on the bull their _banderillas_--barbed darts ornamented with colored paper, and often having squibs or crackers attached. If they succeed, the squibs are discharged and the bull races madly about the arena.
The _matador_ or _espada_ now comes in gravely with a naked sword and a red flag to decoy the bull with, and aims a fatal blow at the animal.
The slaughtered bull is dragged away, and another is let out from the stall. Several bulls are so disposed of in a single day.
What is the Difference between "Alternating" and "Direct" Current?
Strong currents of electricity are generated in the electric central stations and supplied to our homes, street lamps and so forth, in one of the two forms, either "alternating" or "direct." While many of us know which kind is furnished to our homes, everyone does not always understand the difference between the two.
The central station contains a number of powerful dynamo machines, driven usually by steam power. The positive and negative terminals of the dynamo are put in connection with the positive and negative main conductors which are to supply the district, and from these mains smaller conductors branch off to the houses or lamps. All these conductors are of copper, that metal when pure having seven times the conductivity of iron.
Different methods are in use for keeping the supply of electricity steady in spite of the varying demands made upon it. In some systems of distribution, instead of the two main conductors being one positive and the other negative, each is positive and negative alternately, the reversals taking place some hundreds of times per second. The currents are then said to be "alternating." When such reversals do not take place, the currents are said to be "direct."
What was the "Court of Love"?
The "Court of Love" existed in what we call the chivalric period of the middle ages.
It was composed of knights, poets and ladies, who discussed and gave decisions on subtle questions of love and gallantry. The first of these courts was probably established in Provence about the twelfth century.
They reached their highest splendor in France, under Charles VI, through the influence of his consort, Isabella of Bavaria, whose court was established in 1380. An attempted revival was made under Louis XIV by Cardinal Richelieu.
The Story of the Addressograph[28]
If you were asked to enumerate the different kinds of clerical work performed in the modern business office, you would probably fail to mention the writing of names. Yet the writing and rewriting of names is as essential in most offices as the addition of figures or the dictation of correspondence.
In fact, names represent the backbone of nearly every business or organization. There is the list of names of those people you sell to; the names of those people you want to sell to; the names of those people you buy from; the names of those people who owe you money; the names of those people to whom you owe money and the names of those people who work for you. Then, lodges, clubs, churches and other organizations must maintain lists of names of their members; and so the different kinds of lists go on _ad infinitum_.
Now, in most offices, these names must be written and rewritten over and over again--often many times each month--on envelopes, price-lists, statements, checks, pay forms, ledger sheets, order forms, tags, labels, etc. And in many offices the writing of names is still a slow, tedious, drudging task--as the workers in those offices will testify.
The Birth of Mechanical Addressing.
But in one office this monotonous task of writing and rewriting the same names over and over again became such a hards.h.i.+p that the man who had to do it, thinking twenty-five years ahead of his time, had a vision of performing such work mechanically. That vision was the forerunner of the Addressograph.
In the early 90's, Mr. Joseph S. Duncan was manager of a little flour and grist mill in Iowa. The requirements of his business necessitated the daily addressing of 100 quotation cards. Those were the days of pen and ink and the imperfectly developed typewriter. Mr. Duncan's office was small. He was the sole worker in that office--and as the typewriter was still a curiosity in that section of the country, Mr. Duncan was obliged to depend upon pen and ink in addressing his daily price cards.
This routine task wasted a great deal of his valuable time each day. In an effort to finish the work quickly, so that he could devote his attention to more important matters, Mr. Duncan found that he was frequently sacrificing accuracy for speed. Result--his concern often suffered considerable loss of profit because his quotation cards did not reach the people for whom they were intended. Finally, becoming disgusted with inefficient and inaccurate pen and ink addressing methods, Mr. Duncan made a trip to Chicago for the purpose of purchasing a machine for addressing his price cards. But, on visiting the leading stationery and office equipment stores, he was told there was no such machine. He returned to his office resigned to the task of addressing his 100 daily quotation cards by pen and ink. But the drudgery and monotony of this work would not down in his mind. The mistakes and omissions made in addressing these price cards became no less frequent.
Finally, because Mr. Duncan could no longer be reconciled to the drudgery, inaccuracy and expense of hand addressing, he determined to build for himself a machine that would lift from his shoulders this monotonous task.
Builds First Addressograph.
Mr. Duncan invented and built his first addressing machine in 1892. He called it the "Addressograph"--a coined word meaning "to write addresses." Although Mr. Duncan appreciated the saving of time and money and increase in accuracy which his little invention would surely create in the writing of names and addresses, he did not at first realize the great place his remarkable invention was destined to take in the commercial world as a "business energizer" and simplifier of routine work.
Like the first steam engine, telephone or automobile, the first addressograph was crudely simple and of course presented an uncouth mechanical appearance. Mr. Duncan experimented by gluing the rubber portion of a number of hand stamps to a wooden drum. This drum was placed on an operating shaft in the addressograph, so that after the printing of one name and address, the drum revolved so that the next name and address came into printing position. The type impressions thus obtained were fairly readable. But Mr. Duncan soon realized that the idea of gluing the type permanently to a wooden drum was unpractical.
Only a few addresses could be placed around the drum and the method of gluing them permanently into place made it practically impossible to make corrections when changes in address occurred, or to add new names as occasion demanded.
[Ill.u.s.tration: THE FIRST ADDRESSOGRAPH]
Greater flexibility was needed. So Mr. Duncan designed and built what is now known as the first chain addressograph. Individual rubber type characters were pushed into metal type holders with a pair of tweezers.
These type holders were then ingeniously linked together in the form of an endless chain. These chains were placed over a revolving metal drum, and as each separate name and address came to the printing point of the addressograph, the operator pushed down on a vertical stamper rod which pushed the envelope, or whatever form was to be addressed, against the rubber type which was inked just before reaching the printing point.
Here, at last, was a practical addressing machine which enabled the user to accurately print names and addresses--typewriter style--ten times faster than was possible by any other method, and, quite as important, to make changes and additions to the list.
The Beginning of a Great Industry.
By this time, Mr. Duncan had moved his base of operations from Iowa to Chicago. So well was his first practical model of the addressograph received by Chicago business men that he sold the first half-dozen manufactured within a short time. Enthused with his success, Mr. Duncan decided to enter into the manufacture and sale of addressographs on as extensive a basis as the demand for his invention warranted. But to do this it was necessary for him to secure more capital. Consequently, he interested Mr. J. B. Hall--a Chicago business man--in his project, and in January, 1896, Mr. Duncan and Mr. Hall formed a partners.h.i.+p and called it the "Addressograph Company."
Mr. Hall's first step was to find out what the leading business men of his time thought of the addressograph. So he made a trip to New York City--taking with him one of the little hand-operated chain addressographs. Here, Mr. Hall called upon Henry Clews, J. Pierpont Morgan and other prominent business men. He also visited the offices of the large public service and insurance companies. In every case, Mr.
Hall was courteously received, but after demonstrating the addressograph was told that while it was interesting and a step in the right direction, it was still in too primitive a state to prove of any great value in addressing a large list of names.
Answering Demand for Greater Speed.
Naturally, Mr. Hall's first thought on his return to Chicago was to induce Mr. Duncan to build a larger model, capable of greater speed and greater output. Acting upon Mr. Hall's suggestion, Mr. Duncan, in a short time, perfected a larger chain addressograph, operated by foot-lever and embodying several important improvements. As the Addressograph Company was maintaining at that time only a small sales office, a contract was let to the Blackman Machine Company, of Chicago, to build fifteen of these new foot-lever chain addressographs. And it was this new model which caused the addressograph to take its place in the business world as one of the leading office appliances. Many of these new chain addressographs were sold. Having formerly been engaged in the public service field, Mr. Hall was quick to realize the advantages which mechanical addressing offered to gas, electric light, water and telephone companies. As a result, the majority of the first addressograph sales were made to these lines of business.

With the constantly increasing use of the addressograph, suggestions for improvement and further development were freely offered by addressograph customers and just as liberally entertained by Mr. Duncan. As a result of these suggestions, another important advance took place in addressograph development. A customer, after writing words of praise about his addressograph, suggested that if some means could be arrived at to avoid the necessity of setting and resetting the individual pieces of rubber type, a great saving in time and money could be accomplished in making changes and additions to a list of names.
Invents Embossed Metal Address Plate.
After considerable thought, Mr. Duncan hit upon the plan of embossing, typewriter style, characters upon a metal plate. To do this, it was necessary for him to invent and perfect the Graphotype--a machine which writes names and addresses on metal plates almost as quickly as the same data can be written on paper with the typewriter. The first embossed metal plates were linked together in the form of an endless chain, similar to the rubber type plates. A new addressograph was perfected for printing impressions from these embossed metal plates. It was called the No. 2 Chain Addressograph.
The Addressograph Company now had two models to sell. But, owing to the fact that the rubber chain addressograph permitted users to make changes and additions in their own offices, a greater number of machines of this model were sold than of the metal chain addressograph; because, with the latter model, it was necessary for the customer to send to Chicago to have his new metal links embossed with the graphotype for the changes and additions of his list.
By this time, the Addressograph Company had established itself in its own factory in Chicago. Branch offices had also been opened in New York, Philadelphia, Boston and other princ.i.p.al points, and out of these offices was traveling a small but enthusiastic group of salesmen. Many firms, large and small, throughout the country were using and recommending the chain addressograph. And, crude as that model seems now, it was proving a wonderful time and labor saver in the offices in which it was used--and paying back its cost many times each year because of the fact that it accurately printed names and addresses ten times faster than was possible to write such data by pen or typewriter.
A Card Index that Addresses Itself.
As the use of the addressograph increased, Mr. Duncan and Mr. Hall realized the need of a more efficient way of making changes and additions to the list of names. It was important that individual names be located and removed from the list more quickly than was possible with the chain addressograph. Demand for improvement along this line was stimulated by the loose-leaf and card index wave which was just then beginning to sweep the country. And Mr. Duncan, taking the card index idea as a basis, designed what he called the Model "A" or Rubber Card Index Addressograph. Instead of the separate plates being linked together in the form of a chain, they were inserted into a tin holder--called the frame--which closely resembled in appearance a 3 x 5 paper file card. In addition to carrying a printing plate, this frame also carried a paper card bearing a proof of its respective printing plate. In this complete form, these address plates were filed in steel filing drawers like ordinary paper cards. About every fifteenth address plate in a drawer was equipped with a vertical, subdividing tab--numerical, alphabetical or geographical as the case might require.
Each filing drawer carried a printed label showing the contents of the drawer--and by means of these complete card index features it proved a simple matter to locate and remove individual names when making revisions to the list; and, in addition, these features afforded all of the advantages of a perfect reference file, as the paper proof card could be provided with a printed form for retaining memoranda.
[Ill.u.s.tration: RUBBER CARD INDEX ADDRESS PLATE]
Of course, a new addressograph was necessary to handle this card index improvement. And in the Model "A" Addressograph, we find the basic principle of the addressograph of today. A drawerful of plates is emptied into the magazine. The empty filing drawer is placed beneath the addressograph so that after addressing the address plates fall back into the original drawer in their original card index order.
