--N. Y. Illustrated News, July 6.We warn our readers against placing implicit reliance in the accounts of the civil war which come by telegraph. We have private letters front Charleston and New Orleans, and we have others from St. Louis and Baltimore, which put a very different face on matters from that given by the telegraphic despatches. They all represent the feeling in tlhe South as one of the most intense hatred towards the North; they speak of the Baltimoreans as outraged by the presence of so many detested Massachusetts soldiers; they express the utmost confidence in the ultimate victory of the South, and they make light of the blockade and of the chance of servile insurrection.
The telegraph wires all pass through the Northern States. The press despatch published this morning shows how the Administration controls the lines. And under these circumstances there is more faith to be placed in one letter than in half a dozen telegrams. While the telegraphic despatches from New York indicate nothing but ardor for war, private advices represent the people even there as tired of the contest, which can lead to nothing but discontent and disaster. Already are the Democrats of the North beginning to argue among themselves that a strong central Government is not what they have been advocating. Already are the sympathizers with the South beginning to multiply. Already, before the first battle, are the spirits of the Northerners beginning to sink. Meanwhile, both in the North and tlie South, republican institutions are failing, and the advocates of a change to a dictatorship, if not to a monarchy, are gaining ground.
