Letter from President Davis--The Texas papers publish the following letter from the President to Gen Magruder:
Galveston and the vessels in the harbor. The boldness of the conception and the daring and skill of its execution were crowned by results substantial as well as splendid. Your success has been a heavy blow to the enemy's hopes and I trust will be vigorously and effectively followed up. It is to be hoped that your prudence and fact will be as successful as your military ability — retaking every position on the Texas coast. Four suggestions will receive the favorable consideration due to you. The congratulations I tender to you and your brave army are felt by the whole country. I trust your achievement is but the precursor of a series of successes which may redound to the glory and honor of yourself and our country.
