WASHINGTON, February 9, 1906.

The following is published for the information and guidance of all concerned:

1. Computations for elevation scales for seacoast guns, Artillery Notes, No. 20, will hereafter be made by the Artillery Board at Fort Monroe, Virginia, under the direction of the Chief of Artillery. The commanding officer of each artillery district will have prepared and forwarded to the office of the Chief of Artillery, upon blanks to be supplied from that office, a statement showing for each 6-inch, 8-inch, 10-inch, and 12-inch gun in service

(a) Name of fort.

(b) Name of battery.

(c) Model, caliber, and register number of gun.

(d) Tactical number of gun.

(e) Model and register number of carriage.

(f) Height of center of gun trunnions, in firing position, above mean low water.

(g) Extreme variations of tide referred to the plane of mean low water.

2. District engineer officers, when they have such records, will upon application furnish to artillery district commanders the height of the center of gun trunnions in firing position above mean low water. When district engineer officers have no record of such heights they will furnish the height above mean low water of the interior crest of battery, or of each gun emplacement where guns are at different levels in the same battery.

3. Upon the receipt of this information from district engineer officers artillery district commanders will take such measures as may be necessary to determine heights of gun trunnions required, and will promptly transmit them direct to the Chief of Artillery.

4. These heights will be sufficiently exact if they are correct to within a tenth of one foot. Too great care, however, can not be exercised to insure this accuracy, as these computations involve a great amount of labor.

5. Upon the completion of these computations the Ordnance Department will provide elevation scales graduated for capped projectiles and corrected for curvature and for height of center of gun trunnions in firing position.

6. Pending the issue of these scales it will be necessary for
