The Sea-Lion's Repertoire. Long ago trainers recognized in the California sea-lion (_Zalophus_) a good subject for the ring and stage. Its long, supple neck, its lithe body and brilliant nervous energy seemed good for difficult acts. The sea-lion takes very kindly to training, and really delights in its performances. In fact, it enters into its performance with a keen vigor and zest that is pleasing to behold. Let this veracious record of a performance of Treat's five sea-lions and two harbor seals, that I witnessed October 15, 1910, tell the whole story, in order that the reader may judge for himself: 1. Each sea-lion balanced upright on its nose a wooden staff 3 feet long, with a round knob on its upper end. 2. Each sea-lion caught in its mouth a three-foot stick with a ball on each end, tossed it up, whirled it in the air, and caught it again. This was repeated, without a miss. 3. Each sea-lion balanced on the tip of its nose, first a ball like a baseball, then a large ball two feet in diameter. 4. Each sea-lion climbed a double ladder of eight steps, and went down on the other side, _balancing a large ball on the end of its nose, without a miss._ 5. The trainer handed a ball to the sea-lion nearest him, who balanced it on his nose, walked with it to his box and climbed up. 6. Then another sea-lion walked over to him, and waited expectantly until sea-lion No. 1 tossed the ball to No. 2, who caught it on his nose, walked over to his box, climbed up, and presently tossed it to No. 3. 7. A silk hat was balanced on its rim. 8. A seal carrying a balanced ball scrambled upon a cylindrical basket and rolled it across the arena, after which other seals repeated the performance. 9. In the last act a flaming torch was balanced, tossed about, caught and whirled, and finally returned to the trainer, still blazing. Trained Horses. By carefully selecting the brightest and most intelligent horses that can be found, it is possible for a trainer to bring together and educate a group that will go through a fine performance in public. However, some exhibitions of trained horses are halting, ragged and poor. I have seen only one that stands out in my records as superlatively fine,--for horses. That was known to the public when I saw it as Bartholomew's "Equine Paradox," and it contained twelve wonderfully trained horses. My record of this fine performance fills seven pages of a good-sized notebook. While it is too long to reproduce here entire, it can at least be briefly described. The trainer called his group a "school," and of it he said: "While I do not say that any one horse knows the meaning of from 300 to 400 words, I claim that _as a whole_ the school does know that number."
