So strong is my faith in the child's superior memory of primitive life that if the hallboy were to call me up on the telephone to-morrow to say that there was an ichthyosaurus downstairs who wanted to see me, I would not think of deciding what to do about it without first consulting H. 3rd. Curiously enough, Hudson relates one incident which might well be cited in support of the theory that the child is equipped at birth with certain protective instincts, but he passes it over with a different explanation. He says that on a certain afternoon his baby sister, who could scarcely walk, was left alone in a room, and suddenly came toddling to the door shrieking "ku-ku," an Argentine word for danger, which was almost her single articulate possession. Her parents rushed into the room and found a huge snake coiled up in the middle of the rug. The child had never seen a snake before, and there was much speculation as to how she knew it was dangerous. "It was conjectured," writes Hudson, "that she had made some gesture to push it away when it came onto the rug, and that it had reared its head and struck viciously at her." It seems to us that a much more plausible explanation lies in the theory that this child who had never seen a snake profited from some old racial memory of the danger of serpents. Unfortunately, under modern conditions some restrictions must be put on the liberty of small children. I have been told that a child knows instinctively that he must not put his hand into a fire, but he has no age-grounded instinct not to touch a radiator. Still, it might be fair to say that in most New York apartment houses none of them would be hot enough to hurt him much. I can testify that children of less than two years of age are not equipped with any inherited protective knowledge about matches, pins, cigarette stubs, $5 bills, or even those of larger denominations; bits of glass, current newspapers or magazines, safety razor blades (for which, of course, there is an excuse, since the adjective may well mislead a child), watches or carving knives. But all these articles are too recent to come within the scope of inherited primitive knowledge. * * * DECEMBER 17, 1919.--We read Floyd Dell's _Were You Ever a Child?_ to-day and found him remarking: "People talk about children being hard to teach and in the next breath deplore the facility with which they acquire the 'vices.' That seems strange. It takes as much patience, energy and faithful application to become proficient in a vice as it does to learn mathematics. Yet consider how much more popular poker is than equations! But did a schoolboy ever drop in on a group of teachers who had sat up all night parsing, say, a sentence in Henry James, or seeing who could draw the best map of the North Atlantic states? And when you come to think of it, it seems extremely improbable that any little boy ever learned to drink beer by seeing somebody take a tablespoonful once a day."
