JULY 20TH.—The Secretary works too much—or rather does not economize his labor. He procrastinates final action; and hence his work, never being disposed of, is always increasing in volume. Why does he procrastinate? Can it be that his hesitation is caused by the advice of the President, in his great solicitude to make the best appointments? We have talent enough in the South to officer millions of men. Mr. Walker is a man of capacity, and has a most extraordinary recollection of details. But I fear his nerves are too finely strung for the official tread-mill. I heard him say yesterday, with a sigh, that no gentleman can be fit for office. Well, Mr. Walker is a gentleman by education and instincts; and is fastidiously tenacious of what is due a gentleman. Will his official life be a long one? I know one thing—there are several aspiring dignitaries waiting impatiently for his shoes. But those who expect to reach the Presidency by a successful administration of any of the departments, or by the bestowal of patronage, are laboring under an egregious error. None but generals will get the Imperial purple for the next twenty years —if indeed the prematurely made “permanent” government should be permanent.
