also, in shops where large castings or pieces of machinery under construction have to be handled by hoists and travel ing cranes, which would be obstructed by shafting and belt ing, it finds ready application to individual motors on the separate machines. Mining operations are greatly facilita ted by its use as a power where explosive gases are not present and in the allied branch of metallurgy it has accom plished much in the economic reduction of ores. Chemistry, likewise, demands its assistance. These instances give a slight idea of its industrial value, and each person's ex perience and observation will supplement these illustrations with numerous examples in additional proof. Electricity as a source of comfort plays an important part. Light, heat, carriage and ventilation through its application—once a luxury—now are demanded by the traveling public, and are fast becoming necessaries in the home life of large communities. In commerce, the services of electricity are none the less appreciated, and its effects are even more marked. The uses of the telephone and telegraph are familiar. These media of communications are to-day indispensable and busi ness could not be conducted as it is without them. Most marked is the influence of electricity on our intel lectual and our political life. The news of the world is within reach in the space of a few hours. Discoveries and inventions are made known to 'the world in rapid sucession and the intellectual life is thereby greatly stimulated. Men gravitate to the cities not only because they believe employ ment is more readily found there, but because of the intellec tual enjoyment of being in the centres of action ; and the lines that converge in these centres are telegraphic lines. Ellectricity should also help to solve a problem of which it is a partial and indirect cause. The segregation of people in large cities presents many evils. These evils may in mea sure be overcome or ameliorated through the service of the _electricity in Modern Life.
