cacadoos (parrots) of Australia, before descending upon a field or orchard in search of food, send out a scouting party to reconnoitre the region and see that ‘all is well.’ Sometimes a second party is sent. If the report is favourable, the whole band advance and plunder the field in short order. These birds are exceedingly wary and intelligent, and seldom make mistakes. But ‘if man once succeeds in killing one of them, they become so prudent and watchful that they henceforward baffle all stratagems’.[3] A short time ago a parrot at Washington, New Jersey, saved the life of its owner by summoning the neighbours to his relief. Cries of ‘Murder!’ ‘Help!’ ‘Come quick!’ coming from the home of the parrot, attracted the attention of neighbours, who ran to the house to find out the cause. ‘They found the owner of the parrot lying on the floor unconscious, bleeding from a great gash in his neck. He had been repairing the ceiling, and had fallen and struck his head against the stove. It required six stitches to close the wound, and the surgeon said that in only a few minutes the injured man would have been dead. A few years ago this parrot’s screams awakened its owner in time to arouse his neighbours and save them from a fire which started in the house next door.’ A friend of mine, who is thoroughly reliable, tells me that when he was a student at the University of Michigan a few years ago one of the professors of zoology there had a dog who was used by the department for experiments in digestion. The dog was compelled to wear a tube opening downward out of his stomach, and soon grew very weak and emaciated from the constant loss of food, which leaked out through this tube. After a time, however, the dog was observed to be growing unaccountably hale and strong. He was watched, and the poor creature was found to have struck upon an ingenious expedient to save his life. On eating his meal, he would go out to the barn, and, in order to prevent the artificial escape of the contents of his stomach, would lie down flat on his back between two boxes and remain there until his digested food had passed safely beyond the pylorus.
