stage of exchanging photographs, the sequel of which took
place under the most romantic circumstances, not to be related in this
volume.

"It is an ill wind that blows nobody any good," the young man must
often have thought, as he faithfully carried out every instruction
from the scene of action.

All communications for the President and Dr. Leyds were sent to him
(through the White Envelope), because it was not considered safe to
correspond with them direct, even through the medium of the
lemon-juice discovery.

As time went on, this method of communication was used for many
purposes and always with success, but some time after the war, when it
was Hansie's right and privilege to go through the war correspondence
of the young minister of religion, she came upon a letter from Dr.
Leyds to him, in which she read, with growing interest, the following
information:

"I cannot conceal from you that I was startled when I opened the last
white envelope, for I was able to read the whole report, though the
writing was faint, without applying the heating process to it. Perhaps
this letter lay in a warm place near the engine-rooms on the voyage.
Will you not send a timely warning? You could, for instance, say that
the measles have come out and are plainly visible, even without the
application of hot compresses. Those people are quite clever enough to

This warning did not reach Harmony at the time. Perhaps the censor,
trained as he must have been in the art of reading dangerous meanings
into seemingly harmless sentences, decided in his own mind that it
would be advisable to keep the information about the measles to
himself, and consigned the letter to the waste-paper basket.

In time experience taught the conspirators at Harmony that the
greatest care would be necessary in the use of the White Envelope, and
to this they probably owe the fact that it was never found out by the
enemy.

The reproductions given here of specimens of the White Envelope,
showing the address on one side and the written messages on the other,
will give the reader an idea of how this correspondence was carried
on. We do not vouch for the accuracy of the information conveyed in
the following translation of the contents of this envelope. The
figures were quoted from memory, but the general impression conveyed
in this report, of the condition of the commandos at the time, is
reliable and correct. On the si
