only after a period of use. Obvious ones are sometimes reported by the
dealer, but very often they never come to the manufacturer through the
reports of the trade in time to be of service. It took a period of
years for the dealer to realize the importance of enclosed moving
parts. It finally came to him through the reaction developed by women
using the machines. In the same way the manufacture and marketing of
both gas and electric ranges, which has been uniformly efficient, has
overlooked one very important detail. The broiler grids are often so
placed that the steak is an inch and a half away from the flame instead
of one-half inch. With such a broiler, perfect broiling is impossible.
Again a kitchen cabinet may be made of high grade materials but the
hardware proves too light to stand the constant closing and opening.
Such a kitchen cabinet is handicapped in any neighborhood because
constant use makes the minor annoyance a cumulative one, which reacts
directly upon the manufacturer's product.

The vacuum cleaner that is easily sold on the dealer's floor because it
looks big and imposing oftentimes discloses its poor efficiency only
after from four to six months of use. This is due to the fact that from
time immemorial women have ordained a period devoted to housecleaning
twice a year. And it is at this crucial time that they discover if the
routine care of rugs and carpets by their vacuum cleaner has
accomplished a work satisfactory to them. This conclusion is well borne
out by a conversation we had with a large dealer in vacuum cleaners
from the west coast. He freely told us of handling two vacuum cleaners,
one a comparatively inexpensive and absolutely inefficient machine (as
we had proved by test), the other a more expensive and a thoroughly
efficient machine. He claimed that the first proved only a feeder for
the second, since when the woman, after a longer or shorter period of
use, realized that the first machine would not do the work, she
