CIRCUS “HIPPO” IS HARNESSED AND TRAINED TO DRAW CART

After considerable coaching at the hands of an animal trainer, “Lotus,” a circus hippopotamus enjoying winter quarters in California, was taught to haul a two-wheeled cart. A V-shaped tongue attached to a broad band around the creature’s back made traces unnecessary. A bridle of strong leather with the reins attached to the jaws completed the harness, and aided in directing the “river horse” which seemed to enjoy its “stunt” as it walked to its pool and back. Hippopotamuses are said usually to show little intelligence, but they are capable of great speed when in flight from an enemy, or while rushing to an attack after being wounded.

Hen Changed to Rooster by Biologists

TURNING roosters into hens and vice versa is the newest miracle to be attempted by science. Working at the Biological Institute of the College of France a group of scientists are engaged in a series of amazing experiments on the hypophysis gland, a small gland situated at the base of the brain.

It is their belief that by transplanting this gland from the body of a rooster into the body of a hen a complete change of sex will be effected.

In early experiments conducted on various breeds of poultry French Biologists have succeeded in proving their contention.

…STRANGE TESTS GAUGE SENSES OF DUMB CREATURES

“DUMB” animals are learning to talk. Not by ord of mouth, but in roundabout ways they are telling scientists how they feel, what they see and hear, and even what they think about. Age-old mysteries—always the source of controversy—are evaporating as research workers peer into the minds of inarticulate creatures.

Only recently have experimenters succeeded in hurdling what has long been an insurmountable obstacle— the fact that animals, unlike human laboratory subjects, cannot give verbal reports of their experiences and emotions. Through ingenious artifices that establish, in effect, a common language between the animals and their investigators, their innermost sensations are now being revealed.
