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_ assist the horsemen 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.
