The Moving Picture World (April 1907)

IOO THE MOVING PICTURE WORLD. The resolution found in our correspondence columns J is very gratifying, and we appreciate the sentiments ex/ pressed. When a body like the moving picture opera- tors of Philadelphia goes out of its way to move^such a resolution, and three of its principal officers sign the same, it gives us encouragement and makes us feel that we are gaining the confidence and respect of our readers. ternating current, it has a tendency to increase the hi ming, which is very disagreeable. Wires must not spliced. v _^. Before connecting up a lamp for direct current y must know how to tell negative from positive. 1 simplest way to determine negative from positive with* an instrument is to connect the lamp in the manner hen /ifter described. Light the lamp for thirty (30) seconi long enough to let the carbons get hot. The carl that holds the heat the longest is the positive and shou] be the top carbon. If the lower carbon holds heat long< reverse your plug or reverse your wires at the switch. The Carbons. We call our readers' attention to the letters from Mr. G. Kleirie, of Chicago. It is a clarion note to the" trade throughout this vast empire, to get themselves in line to repel the unjust attacks of purity organizations and others who only see evil in every kind of harmless amuse- ment that attracts large masses of people. Every thing in the nature of an arcade or Nickelodeon is "like a red rag to a bull" with such people, and we have no sym- pathy with them. We are heartily in accord with the letters, especially with the clause: "In view of the in* creasing attacks upon users of moving pictures through- out the country, we think it well that all of those inter- ested be aroused to the situation, and we know of no better way to strengthen the interests of all concerned than to eliminate those Him subjects that justify criticism on account of their moral tone." This is the crux of the whole problem, and if manu- facturers of films will only take a word in season, and strive to uplift rather than pander to the lower ideas of mankind, all persecution will cease. Our views are: Give the people the best; there are so many unexplored fields, so many innocent, yet amusing frolics, so vast a field in nature and in portrayal of rural and other life, that it seems to us a sacrilege-and an insult to the intelli- gence of the audiences to put films on exhibition that cause a shudder to pass through one's system, and which at the same time gives the religious community in our midst a right to protest and to tar every nickelodeon with the same brush, and by crying wolf, wolf, making decent people afraid to visit with their female relatives such exhibitions, even in high-class opera houses and theatres. We sincerely hope good will come from this corre- spondence. Hints to Operators By Joseph Menchen. The 'first point is to see that all electrical connections are clean. That all terminals are soldered and every con- nection tight. That no part of the lamp is loose. On al- The carbons should be inclined at an angle as shorn If they are vertical in relation to the condensers, even the negative carbon is advanced out of line with the pos tive, light will also proceed from the negative carbon well as the positive, thus making two sources of li; instead of one—a condition fatal to definition on hi class work. If, however, they are tilted 30 degrees fri the vertical (see illustrations A and B), the lumi spot on the negative carbon is obscured from the coi denser and the crater of the positive carbon is present* in the most favorable way. In setting new carbons to the lamp the larger carboi must be placed in the top or positive carbon holder should be set with its principal axis slightly behind of the negative carbon. When it is necessary, how to employ an alternating current, both carbons must of the same diameter and both should be cored, should be set exactly one over the other in the straight line. Dissolving Effects Can be produced only by the use of two or more terns at once. The lanterns must stand at such angle in reference to each other that the disc of lig on the screen shall be so perfectly registered that it; pears to come from one lantern only. If a third lanti is used, it may be placed above or between the otl tipping it, so that it, too, will register its disc of light t the screen with the others. A slide placed in each I tern will be projected equally, and two or three vies will be jumbled together on the screen. Mec contrivances are placed on the lanterns by which tj light in all may be controlled at will. The light'
