in which case it will be necessary for you
to hunt through old records, copy books, engineering notes, drawings,
and the like, and get a list of all referring to the subject; to make
an abstract of the letters and notes if they are at all complicated;
and finally to lay the whole before the overworked superior in a
business manner, that he largely from recollection, aided by the
references and notes, can write an intelligent answer in a very brief
period. The way not to do it would be to say, "Yes, sir," very
promptly, go off and not more than half read the letter, do something
and be back in five minutes with some question or ill-digested answer;
then upon receiving a polite hint as to the method to be employed, go
off and repeat the operation the next five minutes; then on receiving
a short reply, in what appeared to be an unnecessary tone of voice,
get a little flurried perhaps, do worse next time, and in the end feel
very unpleasant without having accomplished much, and make the
gentleman seeking assistance lament the difficulty in teaching young
men practical work.

It is possible, on the contrary, for a young man to exceed his
instructions and volunteer advice that has not been asked. If he has
unfortunately gone too far for some time and been sharply spoken to,
he may fail the next in not fully doing the work intended. Simply
putting down a column of figures would not necessarily mean tabulating
facts. The arrangement and rearrangement of the columns aid in
classifying such facts, so that the results shown by them will be
readily seen and a great deal of labor saved in examination. A good
rule in a case of this kind is to try and find some work done by other
parties of a similar nature, and thereby ascertain what is needed and
expected. Reasonable questions to ascertain, where records are to be
found and the kind of records accessible, are always proper if made at
the proper time without interrupting an immediate train of thought;
and with such information as a start, if a young man will endeavor to
imagine himself in a place like that of the one who has finally to
decide, and try to ascertain just what information will probably be
required, then patiently go to work to find and present it in
condensed shape, he from that moment really begins to be useful and
his services will be rapidly appreciated. It is a good rule always to
keep the memoranda obtained in accomplishing a result of this kind; so
that if furthe
