cated series of operations, but the time required for that
is considerable. It is not a .very efficient procedure. Some
consideration has been given to the extent to whiCh some
of the new high-speed multipliers will meet the problem,
but study of the situation so far indicates that we are still
considerabl y handicapped in the direction of getting these
measures of the accuracy of the results of sample data.
There is a need for further development which will increase
the use of sampling by making it possible to measure
the accuracy of the results more speedily.
I have brought several types of exhibits in which some
of you may be interested, a number of pamphlets and
bulletins which show cases in which we have made direct
use of machine tabulation sheets for publication: some of
our housing reports, some of our foreign trade reports,
SCIENTIFIC COMPUTATION
and a job we did for the Air Forces, on all of which we
printed the 405 sheets directly. If there are questions you
want to ask about them, feel free to write in. There are
also several copies of the booklet on work of the Census
Bureau-Fad-Finder for the Nation. If any of you want
a copy of that, I would be very glad to furnish it.
DISCUSSION
Mr. Tillitt: At one time the Bureau of the Census
turned out a little sheet called "Tab Tips." Is that distributed
any more?
Mr. Eckler: I think I have the first forty. If anything of
that sort is being distributed now, it has not come to my
attention.
