_jiujutsu_ or _yawara_,
horsemanship, the use of the spear, tactics, caligraphy, ethics,
literature and history. Of these, _jiujutsu_ and caligraphy may require
a few words of explanation. Great stress was laid on good writing,
probably because our logograms, partaking as they do of the nature of
pictures, possess artistic value, and also because chirography was
accepted as indicative of one's personal character. _Jiujutsu_ may be
briefly defined as an application of anatomical knowledge to the purpose
of offense or defense. It differs from wrestling, in that it does not
depend upon muscular strength. It differs from other forms of attack in
that it uses no weapon. Its feat consists in clutching or striking such
part of the enemy's body as will make him numb and incapable of
resistance. Its object is not to kill, but to incapacitate one for
action for the time being.

A subject of study which one would expect to find in military education
and which is rather conspicuous by its absence in the Bushido course of
instruction, is mathematics. This, however, can be readily explained in
part by the fact that feudal warfare was not carried on with scientific
precision. Not only that, but the whole training of the samurai was
unfavorable to fostering numerical notions.

Chivalry is uneconomical; it boasts of penury. It says with Ventidius
that "ambition, the soldier's virtue, rather makes choice of loss, than
gain which darkens him." Don Quixote takes more pride in his rusty spear
and skin-and-bone horse than in gold and lands, and a samurai is in
hearty sympathy with his exaggerated confrere of La Mancha. He disdains
money itself,--the art of making or hoarding it. It is to him veritably
filthy lucre. The hackneyed expression to describe the decadence of an
age is "that the civilians loved money and the soldiers feared death."
Niggardliness of gold and of life excites as much disapprobation as
their lavish use is panegyrized. "Less than all things," says a current
precept, "men must grudge money: it is by riches that wisdom is
hindered." Hence children were brought up with utter disregard of
economy. It was considered bad taste to speak of it, and ignorance of
the value of different coins was a token of good breeding. Knowledge of
numbers was indispensable in the mustering of forces as well, as in the
distribution of benefices and fiefs; but the counting of money was left
to meaner hands. In many feudatories, public finance w
