Senatorial power had been a coefficient of Presidential weakness

Senatorial power had been a coefficient of Presidential weakness, and for thirty years, Presidents had either like Grant, or indecisive, or simply cowed by the mighty Senate. But with the crack of the assassin’s gunshot that struck down McKinley, and, to the rage of Senator Mark Hanna, put “that dammed cowboy” Theodore Roosevelt in the White House, the era of weak Presidents was over.

Embarrass his Holiness by associating with any Methodists in Rome

The Vatican advised that Pope Pius X would grant him an audience on the fifth of April, providing that he did not embarrass his Holiness by associating with any Methodists in Rome

This is bullier!

[At Yosemite, in 1903] For the next forty-eight hours, the boy in Roosevelt, never quite supressed, reveled in his wild surroundings. “This is bully!” he yelled, when Muir burned a dead tree for him and the sparks hurtled skyward. After another night our, he awoke at Glacier Point, and was intrigued to find himself buried under four inches of snow. “This is bullier!”

The president usually had an open book on his desk, and was quite capable of snatching it up when conversation flagged

Petitioners visiting the Executive Office learned to keep talking, because the president usually had an open book on his desk, and was quite capable of snatching it up when conversation flagged.

Few, if any Americans could match the breadth of his intellect and the strength of his character

Yet there was no doubt that Theodore Roosevelt was peculiarly qualified to be President of all the people. Few, if any Americans could match the breadth of his intellect and the strength of his character. A random survey of his achievements might show him mastering German, French and the contrasted dialects of Harvard and Dakota Territory; assembling fossil skeletons with paleontological skill; fighting for an amateur boxing championship; transcribing birdsong into a private system of phonetics; chasing boat thieves with a star on his breast and Tolstoy in his pocket; founding a finance club, a stockman’s association, and hunting-conservation society; reading some twenty thousand books and writing fifteen of his own; climbing the Matterhorn; promulgating a flying machine; and becoming a world authority on North American game mammals. Any Roosevelt watcher could make up a different but equally varied list.

If it had been I who had been shot, he wouldn’t have got away so easily … I’d have guzzled him first

Sincere, if slight, grief for McKinley – a cold-blooded politician he had never much cared for – struggled in Roosevelt’s breast with more violent emotions regarding the assassin, Leon Czolgosz. In his opinion, those bullets had been fired, not merely at a man, but at the very heart of the American Republic. They were an assault upon representative government and civilized order. Unable to contain his rage, he leaned forward and blurted a excoriation of Czolgosz in to the rain. “If it had been I who had been shot, he wouldn’t have got away so easily … I’d have guzzled him first.”

Unwilling to disturb his sleeping family, he had no choice but to break into his new home

On the icy midnight of Sunday, 1 January 1899, the silence brooding over Eagle Street, Albany, was disturbed by the sound of smashing glass. Theodore Roosevelt, Governor, had stayed out late after dinner (talking too much, as usual), with the result that forgetful servants had locked him out of the Executive Mansion. Unwilling to disturb his sleeping family, he had no choice but to break into his new home.

Happiest when he conquers, but quite happy if he only fights

Teddy is consumed with energy as long as he is doing something and fighting somebody … he always finds something to do and somebody to fight. Poor Cabot must be successful; while Teddy is happiest when he conquers, but quite happy if he only fights.

The only personality whose lusty presence stamps every page is that of Theodore Roosevelt

Today the book [Roosevelt’s biography of Benton] is dismissed as historical hackwork. This reputation is not fair. Benton may be unread, but it is not unreadable. Certainly there are long stretches of of rather dogged narrative, such as the chapters devoted to the politics of nullification and the redistribution of federal surplus funds. One can read the book from cover to cover without finding our what its subject looked like. Secondary characters, such as Andrew Jackson and Daniel Webster, are merely referred to, like names in an encyclopedia. The only personality whose lusty presence stamps every page is that of Theodore Roosevelt. Herein lies the book’s main appeal, but its scholarship is so dated to be spurious now.

Puzzled by a shopkeeper’s refusal to sell him, on sight, a full pound of arsenic

[at 14, Roosevelt was] puzzled by a shopkeeper’s refusal to sell him, on sight, a full pound of arsenic. “I was informed that I must bring a witness to prove that I was not going to commit murder, suicide or any such dreadful thing, before I could have it!”

He no sooner thinks than he talks

I am told that he no sooner thinks than he talks, which is a miracle not wholly in accord with an educational theory of forming an opinion.

Mark Twain is not alone in thinking the President insane.

Mark Twain is not alone in thinking the President insane. Tales of Roosevelt’s unpredictable behavior are legion , though there is usually an explanation. Once, for instance, he hailed a hansom cab in Pennsylvania Avenue, seized the horse, and mimed a knife attack upon it. On another occasion he startled the occupants of a trolley-car by making hideous faces at them from the Presidential carriage. It transpires that in the former case he was demonstrating the correct way to stab a wolf; in the latter he was merely returning the grimaces of some small boys, one of whom was [his son] the ubiquitous Quentin
