"77 ROUNDS FIRED, SIR" 529 Reserve regiments had to be carried on simultaneously during the firstfour weeks of camp, the battery commander was able to dovetail these two classes of training very nicely. Two DeHaviland planes with the necessary <strong>Air</strong> Corps personnel, attached to the regiment, furnished splendid cooperation throughout. The preliminary training of the battery was progressive and consisted of calibration firings, wind, burst, and trial shot problems, and preliminary firings at towed target with one, two, and then four guns. Experience had indicated that changing atmospheric temperatures affected burning of fuzes considerably. Therefore in order to obtain accurate calibration data the battery commander fired trial shots concurrently from the four guns. All gunners quadrants were tested and accurately adjusted for any errors before firing. Guns were fired in order from right to left,each piece firing as soon as the data from the ALTITUDE (YAROS) o '""" 11" 'l, ' I ," "/",,,/,,,, ..,..,.., 'l",/,""1"'''''''''''''1'''' 1""1"'''''1 '1"'"'''''''' "1"'"1''''/,'''''''''1''' o I 2 3 • 7 • ~ W I' E B H ~ ~ 0 ~ ~ ~ ~ TiME OF ASCENSION O-lINUTES) I: ,I ")1''''1' t ..1 • I ZD .. 000 , , I j •0 ANGULAR HEIGHT (MilS) """ ... noo "'" I , , , I I , , I , I I I , 7 .

In this manner four trial shots were fired from all four guns in less than ten minutes elapsed time. Accuracy rather than speed was striyen for however. Four sets of calibration firings were conducted during the preliminary training period so that the battery commander had ample data on which to base a standing correction on certain guns before going into record practice. All guns were carefully boresighted just prior to any firing. During the training of gun pointers frequent competitions were held between gun sections firing against time to speed up rate of fire. ::\0 meteorological station being ayaiIable in the field, wind data was obtained from an Emergency Vector "\\ind Chart which was designed by one of the officers of the regiment. Based on knowledge gained from his pre,ious experiments in the ascensional rate of balloons he constructed a scale of altitudes in yards against time of ascension in minutes for the six-inch balloon inflated to twenty-four
