1st-The daily reconnaissances necessary for the safety of the camps, posts, etc. Their object is to discover the movements and preparations of the enemy, and the dispositions of his advanced posts. These reconnaissances. are made by small detachments, and by patrols from the main guard. They should not be made at the same hour every day nor by the same routes.

2nd-Special reconnaissances designed to ascertain--the topography of the country, the means which the country can furnish for attack and defense. the position of the enemy, and his strength at different points; and in fine, to furnish information necessary for the determination of the method of operating, moving the different columns, etc. These reconnaissances are conducted in accordance with instructions from the general-in-chief, the commander of separate corps, divisions, etc.

3rd-Offensive reconnaissances, which ordinarily should be ordered only by the general-in-chief; for the purposes of ascertaining as accurately as possible, the position and strength of the enemy.

Reporting-The result of every reconnaissance should be presented in a clear, simple and positive report. The officer making the report must expressly distinguish between what he has himself seen and what he has learned from others without being able himself to verify the accuracy of it. He adds to the report, any drawings necessary to represent the ground, the positions of the enemy, etc.
