��This colorful display of mechanical toys filled the whole side of the court of a depart- ment store. It held crowds of delighted children spell-bound each day for weeks

��Mother Goose, John Potter, and All the Rest Attended Toy Town Show

WHERE is the mysterious land from which all toys come? New York caildren re- cently had an op- portunity to look at it. A large de- partment store put on a display show- ing all the charac- ters childhood knows well, actual- ly at work. Balls revolved, heads bobbed, "teeter- totters" see-sawed, a goose flapped its wings; everywhere was action enough to catch and hold the entire attention of the crowds of delighted children. The panorama was designed by W. F. Larkin of the store's force, and nearly four months' work was involved in its production. All the figures were mechanically operated by a four-horsepower electric motor.

���A New Cure for the Capers of Hot-Air Furnaces

FREDERICK E. JENKS of New Haven reme- dies the ills of the hot air furnace by placing a large tank of sand inside its top, and by using an ordinary coal stove for producing heat. The sand ab- sorbs heat when the stove is hot and then radiates it uni- formly after the fire in the stove has died down and the heat is needed.

��Here the invent- or has placei a parlor stove in- side the shell of a furnace. The idea seems to work well. The sand is just as useful in an ordinary furnace
