Page 433 - TV/FASTER of human destinies am I ; Fame, love, and fortune on my footsteps wait; Cities and fields I walk ; I penetrate Deserts and seas remote, and, passing by Hovel and mart and palace, soon or late I knock unbidden once at every gate. If sleeping, wake ; if feasting, rise before I turn away. It is the hour of fate...
Page 592 - BETTER trust all and be deceived, And weep that trust and that deceiving, Than doubt one heart, that, if believed, Had blessed one's life with true believing.
Page 707 - Next, there are those who do the right thing only when necessity kicks them from behind, and these .get indifference instead of honors, and a pittance for pay. This kind spends most of its time polishing a bench with a hard-luck story.
Page 83 - We do not admire the man of timid peace. We admire the man who embodies victorious effort; the man who never wrongs his neighbor, who is prompt to help a friend, but who has those virile qualities necessary to win in the stern strife of actual life.
Page 707 - The world bestows its big prizes, both in money and honors, for but one thing. And that is Initiative. What is Initiative? I'll tell you: It is doing the right thing without being told. But next to doing the thing without being told is to do it when you are told once.
Page 82 - You work yourselves, and you bring up your sons to work. If you are rich and are worth your salt, you will teach your sons that though they may have leisure, it is not to be spent in idleness; for wisely used leisure merely means that those who possess it, being free from the necessity of working for their livelihood, are all the more bound to carry on some kind of non-remunerative work in science, in letters, in art, in exploration, in historical research work of the type we most need in this country,...
Page 132 - ... permanence. Other great business interests are awakening to the need of forest preservation as a business matter. The Government's forest work should receive from the Congress hearty support, and especially support adequate for the protection of the forest reserves against fire. The forest-reserve policy of the Government has passed beyond the experimental stage and has reached a condition where scientific methods are essential to its successful prosecution. The administrative features of forest...
Page 82 - A life of slothful ease, a life of that peace which springs merely from lack either of desire or of power to strive after great things, is as little worthy of a nation as of an individual. I ask only that what every self-respecting American demands from himself and from his sons shall be demanded of the American Nation as a whole.
Page 433 - MASTER of human destinies am I! Fame, love, and fortune on my footsteps wait. Cities and fields I walk; I penetrate Deserts and seas remote, and passing by Hovel and mart and palace— soon or late I knock unbidden once at every gate! If sleeping, wake — if feasting, rise before I turn away. It is the hour of fate, And they who follow me reach every state Mortals desire, and conquer every foe Save death; but those who doubt or hesitate, Condemned to failure, penury, and woe, Seek me in vain and...
Page 132 - The study of the opportunities of reclamation of the vast extent of arid land shows that whether this reclamation is done by individuals, corporations, or the State, the sources of water supply must be effectively protected and the reservoirs guarded by the preservation of the forests at the headwaters of the streams. The engineers making the preliminary examinations continually emphasize this need and urge that the remaining public lands at the headwaters of the important streams of the West be...
