The crowded condition of our columns this morning necessitates the omission of our usual Summary of the News.

There never was a better illustration of the power of the law when honestly enforced than was furnished yesterday by the Police authorities. There was a determination to preserve the peace, and the bare announcement of the intention was sufficient. The police were on hand in large numbers to enforce the decree, but they were not called upon to use the power with which they were clothed. Their presence was all that was necessary. There were hundreds of evil disposed persons on the streets, whose greatest delight would have been to "throw a brick," but they cowered before the law. A few quarrelsome individuals were promptly marched off to the Station House on evincing a disposition to create trouble. It is with feelings of genuine satisfaction that ew call attention to the praiseworthy action of the Police Commissioners and the good conduct of the police. They had an arduous duty before them, and they did it well. The conduct of the colored people cannot be too highly commended. We have not heard of a single disorderly act laid to their charge. In many instances they endured petty insults rather than encourage a disturbance by resenting them.

The impression made by the demonstration upon the mass of our citizens we believe to be good. They have bever before had an opportunity of witnessing so much of the manhood of the race. He is a hardened sinner indeed that can scoff and sneer in the presence of such orators as Frederick Douglass and John M. Langston. Ability such as theirs compels respect from the most unwilling minds.

There was also much that was pleasing in the procession. The bright uniforms and gay banners always interest the crowd of spectators, and more or less disarm hostility. Expectation is awakened, the eye is pleased, and prejudices are for the moment forgotten. A celebration like that of yesterday involves much expense, and requires the time and labor of many persons who can scarcely afford the sacrifice, yet, in the end, we believe then results to be beneficial. Public opinion is insensibly molded by such influences, and let us hope that the good impressions made yesterday will bring forth their fruit in due time.
