Perhaps the war, or possibly an increase in class consciousness, or unionization of spirits, or whatever, has greatly energized the ghost in our day and given him both ambition and strength to do more things than ever. Maybe "pep tablets" have been discovered on the other side as well! No longer is the ghost content to be seen and not heard, to slink around in shadowy corners as apologetically as poor relations. Wraiths now have a rambunctious vitality and self-assurance that are astonishing. Even the ghosts of folks dead so long they have forgotten about themselves are yawning, stretching their skeletons, and starting out to do a little haunting. Spooky creatures in such a wide diversity are abroad to-day that one is sometimes at a loss to know what to do "gin a body meet a body." Ghosts are entering all sorts of activities now, so that mortals had better look alive, else they'll be crowded out of their place in the shade. The dead are too much with us! Modern ghosts are less simple and primitive than their ancestors, and are developing complexes of various kinds. They are more democratic than of old, and have more of a diversity of interests, so that mortals have scarcely the ghost of a chance with them. They employ all the agencies and mechanisms known to mortals, and have in addition their own methods of transit and communication. Whereas in the past a ghost had to stalk or glide to his haunts, now he limousines or airplanes, so that naturally he can get in more work than before. He uses the wireless to send his messages, and is expert in all manner of scientific lines. In fact, his infernal efficiency and knowledge of science constitute the worst terror of the current specter. Who can combat a ghost that knows all about a chemical laboratory, that can add electricity to his other shocks, and can employ all mortal and immortal agencies as his own? Science itself is supernatural, as we see when we look at it properly. Modern literature, especially the most recent, shows a revival of old types of ghosts, together with the innovations of the new. There are specters that take a real part in the plot complication, and those that merely cast threatening looks at the living, or at least, are content to speak a piece and depart. Some spirits are dumb, while others are highly elocutionary. Ghosts vary in many respects. Some are like the pallid shades of the past, altogether unlike the living and with an unmistakable spectral form--or lack of it. They sweep like mist through the air, or flutter like dead leaves in the gale--a gale always accompanying them as part of the stock furnishings. On the other hand, some revenants are so successfully made up that one doesn't believe them when they pridefully announce that they are wraiths. Some of them are, in fact, so alive that they don't themselves know they're dead. It's going to be a great shock to some of them one of these days to wake up and find out they're demised!
