Read the excerpt from "Tools of the Spymaster." The idea of invisible ink had been around for a long time. Write using lemon juice as ink, for instance, and the writing will be invisible. Heat the paper, and the writing will appear, looking as if it were written in brown ink. British agents used two types of ink. One could be made visible by holding the paper over the flame of a candle; the other could be read by applying a common chemical. Major John Andre, the chief British intelligence officer in New York, told his agents to put an F in the corner of letters containing invisible ink needing fire to read and A for those needing acid.

The author’s main purpose in this excerpt is to

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
