Black ink is always preferable. That which is free from sediment and
flows well, should be selected. Use an inkstand with broad base as
being less liable to upset. With persons in learning to write it is
perhaps best to have a quality of ink which is perfectly black when
put on the paper, in order that they may see the results of their
labor at once. Business men and accountants prefer a fluid ink,
however, which, although not black at first, continues to grow black,
and becomes a very bright and durable black, notwithstanding the
action of light and heat. Avoid the use of fancy colored inks,
especially the more gaudy, such as blue, red or green, in writing all
documents which you desire to command attention and respect.
