Now they not only conquer Nature and compel her
t. give up her caprices in the matter OF heat ana
cold. but they want an exact indication OF what
that artlfciallv produced temperature is, and they
demand also an automatic registering apparatus
SO that they can look back over a term of years
and see Just what the variations have been. II is

SIT in his Office and tell at glance Just what the

warehouse and whether his refrigerating machinery
Is working evenly. for n rise of temperature AT any
one pont might spoil thousands of dollars worth OF
provisions stored there.
Take the case of a ship with cargo of fruit
