eat care should be exercised to prevent the Staff becoming
larger than is necessary, and there is some danger that the ignorant may
gauge the value of the Staff by its size.

Von Schellendorff says on this subject:

"The principle strictly followed throughout the German Service of
reducing all Staffs to the smallest possible dimensions is moreover
vindicated by restricting every Staff to what is absolutely necessary,
and by not attaching to every Army, Army Corps and Divisional Staff
representatives of all the various branches and departments according to
any fixed rule.

"There cannot be the slightest doubt that the addition of every
individual not absolutely required on a Staff is in itself an evil. In
the first place, it unnecessarily weakens the strength of the regiment
from which an officer is taken. Again it increases the difficulty of
providing the Staff with quarters, which affects the troops that may
happen to be quartered in the same place; and these are quite ready
enough, as it is, occasionally to look with a certain amount of
dislike--though in most cases it is entirely uncalled for--on the
personnel of the higher Staffs. Finally, it should be remembered--and
this is the most weighty argument against the proceeding--that _idleness
is at the root of all mischief_. When there are too many officers on a
Staff they cannot always find the work and occupation essential for
their mental and physical welfare, and their superfluous energies soon
make themselves felt in all sorts of objectionable ways. Experience
shows that whenever a Staff is unnecessarily numerous the ambitious
before long take to intrigue, the litigious soon produce general
friction, and the vain are never satisfied. These failings, so common to
human nature, even if all present, are to a great extent counteracted if
those concerned have plenty of hard and constant work. Besides, the
numbers of a Staff being few, there is all the greater choice in the
selection of the men who are to fill posts on it. In forming a Staff for
war the qualifications required include not only great professional
knowledge and acquaintance with service routine, but above all things
character, self-denial, energy, tact and discretion."

The struggle against the depredations of the enemy submarines during the
year 1917 was two-fold; _offensive_ in the direction of anti-submarine
measures (this was
