Condition of water.—The first duty of an engineer when he enters his boiler room in the morning is to ascertain how many gauges of water there are in his boilers. Never unbank or replenish the fires until this is done. Accidents have occurred, and many boilers have been entirely ruined from neglect of this pre- caution. 2. Low water.—In case of low water, imme- diately cover the fires with ashes, or, if no ashes are on hand, use fresh coal. Do not turn on the feed under any circumstances, nor tam- per with or open the safty valve. Let the steam outlets remain as they are. 3. In cases of foaming.—Close throttle and keep closed long enqugh to show level of water. If that level is sufficiently high, feeding and blowing will usually suffice to correct the evil. In cases of violent foaming, caused by dirty water, or change from salt to fresh, or vice versa, in addition to the action before stated, check draft and cover fires with fresh coaL 4. Leaks.—When leaks are discovered they should be repaired as soon as possible. 5. Blowing off.—Blow off eight or ten inches at least once a week; every Saturday night would be better. In case the feed becomes muddy, blow out six or eight inches every day. Never blow entirely off except when boiler needs scraping or repairing, and then not until fire has been drawn for at least ten hours, as boilers are often seriously injured or ruined by being emptied when the walls are hot. Where sur- face blow cocks are used, they should be
