Since there are 288 days or 41.1 weeks in the required military-training period (September first to the fifteenth day of June next ensuing), a boy must drill 123.3 hours. This represents on the average 12.33 man work units. For example, if a boy grows 1.2 acres of potatoes or takes entire charge of .6 acres of berries, including cultivation, picking, marketing, etc., for a period of one year, he has spent in productive agricultural work the number of hours required for military drill.
