Third.—Three Memoirs.
Three memoirs on different parts of the course, other than the geological, will be made immediately after the interrogations relative to each . Particular data will be furnished to each Sub-Lieutenant. Three attendances in the halls of study will be allowed for these memoirs.
Fourth.—Geological Excursions.
Three geological excursions will be made in the environs of Metz by groups of ten or twelve Sub-Lieutenants under the direction of the Professor, and at the period of the out-of-door work, so as not to interfere with the current work in the halls. The first excursion will have for its object the study of the lias and lower oolite, met with in the vicinity of Metz. If the time will admit of it, a reconnaissance will be made to the great oolite at Taumont or at Amanvillers.
The second excursion will be made in the direction of Gorze for the study of the lower oolitic formation and to trace it up to Bradford clay, where an important fault occurs in this direction near to Metz. The study of this fault will be the great object of this excursion.
The third excursion will be made in the direction of Forbach, meeting with the lias, chalk-colored freestone, &c.
Three entire days will be devoted to these excursions, and each Sub-Lieutenant will enter his observations in a note-book, and make a certain number of s, and report the results of these excursions in three memoirs in a specified time.
Fifth.—Manipulations relative to Moulding in Earth or Sand.
These mouldings of projectiles will be made by s of ten or twelve Sub-Lieutenants, two attendances of three hours each being devoted to them, one for ordinary and the other for hollow projectiles.
The manipulations for the moulding of cannon will be executed by the Professor.
