Page 6 - Paul hath persuaded and turned away much people, saying that they be no gods, which are made with hands : and not only is there danger that this our trade come into disrepute ; but also that the temple of the great goddess Diana be made of no account, and that she should even be deposed from her magnificence, whom all Asia and the world worshippeth. And when they heard this, they were filled with wrath, and cried out, saying, Great is Diana of the Ephesians.
Page 7 - Wherefore, if Demetrius, and the craftsmen which are with him, have a matter against any man, the law is open, and there are deputies: let them implead one another.
Page 29 - These curves of failure and tables of percentages can be used to determine closely the length of service railroad companies are getting out of the treated ties now in their tracks without waiting many years. By comparing the removal with the number of ties treated in any one year it will show which curve of failure it is following, and give the probable mean life of the tie, which is the essential thing to know. In making comparisons with European records to determine the probable average life of...
Page 7 - We must abolish everything that bears even the semblance of privilege or of any kind of artificial advantage, and put our business men and producers under the stimulation of a constant necessity to be efficient, economical, and enterprising, masters of competitive supremacy, better workers and merchants than any in the world.
Page 27 - Its own name, but as au adulterant of coal tar creosote. It contains some of the most important constituents of coal-tar creosote, as well as those of the paraffin series. Its analysis by fractional distillation is sometimes identical with that of the coal-tar product, and it is probable that after injection into the timber it would show no more rapid volatilization.
Page 42 - Navy, made known to the public his new process for treating wood. The invention consists of destroyng the tendencies of certain vegetable and animal substances to decay by submitting them to the action of chloride of zinc. The degree of dilution recommended by Mr. Burnett is one part volume by fifty parts of water. At first the method of impregnation was by immersion in open tanks.
Page 36 - Stockholm called attention to the use of alum for preserving wood from fire,, stating that wood or timber for the purpose of building may be secured against the action of fire by letting it remain for some time in water wherein vitriol, alum or any other salt has been dissolved which contains no inflammable parts. In 1815 Mr. Wade found that alum was not a good preservative and caused speedy decay of timber. In the same year Mr.
Page 43 - As the experience of those railroads that have from twenty-five to twenty-six years impregnated their sleepers with chloride of zinc, under pressure, after steaming and abstracting the sap, has been very satisfactory, and as this system costs only one-third or less compared with impregnation with creosote or corrosive sublimate, many of the railroads have adopted the chloride of zinc process.
Page 23 - Some method or process can perhaps be devised whereby it would be unnecessary to separate the ties or timbers into so many groups for treatment. It is easy enough to discuss the probable behavior of certain species from a purely theoretical point of view, taking into consideration the physiological structure of the different timbers, their organic cell contents, their percentage of heart wood and sap wood, etc., but experience has shown very emphatically that the controlling factors which influence...
