The report finds that although large number
OF patents have been granted to various inventors
looking TO the use Of pneumatic tubes OF sufficient

London The Idea was 10 exhaust the air from
long metal tube by two large cylinders inc TUBE
attached by means Of a cord. So far as is known
no further effort was made In this DIRECTION for
more than one hundred years when In 1870 there
was an attempt TO move small carriages on rails
