It is, in reality, the most successful avenue by which he may obtain the theory, for he learns the abstract more readily from concrete... more...

CHAPTER 2.   Infantry Drill Regulations. The greatest lesson of the present war is that the keynote of success is discipline. In trenches the direct control of the men is even less than in extended order in open warfare, and only thoroughly disciplined troops with a trusted leader can hope to succeed. The successful officer will show anger or irritation only in rare cases, and then by design: he will know his men individually and be as... more...

His approach was largely empirical, as we use the word today. This study suggests that, despite the glamor of today's sophisticated methods of calculation, a highly developed intuitive sense,... more...

FOREWORD We are not tied to a desk or to a bench; we stay there only because we think we are tied. In Montana I had a horse, which was hobbled every night to keep him from wandering; that is, straps joined by a short chain were put around his forefeet, so that he could only hop.

This statement is just as true today as it was when written 1900 years ago by this early writer on European agriculture. Every man who loves the calling and has an ambition to become a successful farmer should understand that no... more...
