The great debate in the Senate is not yet ended, nor, as far as we see, is it < likely soon to be. A new topic was in- 6 troduced into the debate, the other day, by Mir. GRuNDY, in defence of the re- movals from office under the present ad- ministration, which is likely to proIong the discussion. This topic has already s produced some most able debate, and will not, we apprehend, be very soon exhausted.

 Some of our contemporaries, we ob- serve, regret this widely discursiye de- bate, and think the time misspent which is employedin it. Not so we.

Nor are the benefits of these collisions of opin- ion, and consequent effusions of light, confined to the walls of the Capitol. No; they penetrate the remotest corners of the Republic, and enlighten all its bor- ders. The speeches delivered in such debates are, i'll truth, school books in the system of national education. They do not answer the elementary purpose of ss teaching the young idea how to shoot but they serve to mature its af- ter blossoms into fruit, and to give to the fruitits wholesome flavor and medica- ting influences. For all the purposes of instruction in the practical science of government, the perusal of one good speech, in such debate, is worth a whole years study of the ponderous toHaesof scholastic exercises, with which the heads of our collegians are general ly filled, to the exclusion of all proper instruction in the theory or practice oi their own government.

 This debate has, it is true, grown up unexpectedly. upon question not par. ticularly inviting it. But, when the heart is full, the mouth will speak ;and under such circumstances, one occasion serves as well as another. In the early history of this Government, following the practice of the British Parliament the debate in each House, early in each session of Congress, upon the answer tc the Presidents speech, furnished the op. portunity for this general disburthening
