One of the most useful services of a great Exposition, especially as it relates to the world of art, is its service in bringing to the attention of the public the power of new and rising stars on the horizon of achievement. Albin Polasek has made his work generally felt at this Exposition, where he received a silver medal. He is one of the most talented sculptors of the American Academy at Rome. He won honorable mention in the Paris Salon in 1913, and the Prix de Rome in 1910. He was the holder of the Cresson scholarship. His "Sower" was the culminating work of his early labors, the product of his final year at Rome, in which year a heroic figure is required of every student. It caused the critics to prophesy for this sculptor the future that is developing. Mr. Polasek's work has the same unassailable rigor of truth as that of Charles Grafly, who was his teacher. "The Sower" ennobles an humble theme. It has sweep and life and distinction of bearing. In "The Girl of the Roman Compagna," close at hand in this Colonnade, the sculptor shows his equal power in a softer theme. The Roman girl is a well-poised and beautiful expression of the spirit of old Rome in the days of her grand simplicity. The Bison Garden Exhibit, South Approach These mighty monarchs of the plains, now disinherited by human progress, the American bisons, are here more than portrayed; they are realized. Their essential characteristics, their strong mass, bulky without clumsiness, are made present and convincing in these two statues by A. Phimister Proctor, a master of animal sculpture. There is good reason for the living and sharp aspect of these plaster models. They are not copies of the permanent statues; they are the sculptor's own original plasters from which the permanent pieces were cast. A number of Mr. Proctor's animal studies stand in the great zoological parks of our nation. He does not idealize or humanize the beasts he depicts; but he understands them and reverses the underlying life that gives them their racial and personal individuality. Partly his Canadian love of the wild, partly a technician's delight in mastering this difficult phase of art, has caused a lifelong devotion to animal studies. They are not photographic, but combine the qualities of sculptural beauty with rugged and imposing freedom. A varied and stimulating collection of Mr. Proctor's work, exhibited at the Exposition, has won a gold medal. It includes the famous "Princeton Tiger." The Scout Garden Exhibit, South Lagoon
