Apartment-Window Cage Protects English Tots
Enclosed in a wire cage suspended from an apartment window, English children play in the sunlight and fresh air while their mothers are busy with housework. The cage, made of wire netting is strongly braced and is guarded on the apartment side by a cloth net which prevents children from crawling back into the room. Loaned by an infant welfare center to families with no gardens, the portable balcony is apparently popular with children and mothers. The demand exceeds the supply.
