"BlIND MANS BUFF"
 AT SEA
(From London Times)

(frOm LOndOn I1meS)
 The methods by which the submar- inc is necessarily harried and fought cannot be more than roughly indicat- ed but from discreet extracts from the logs of vessels engaged in the campaign it is possible to gain good idea of the perils, excitements. and successes of the submarine hunter. The difficulty in dealing with under water craft is to know when your en- emy has actually been destroyed. When, for instance commander can write down in his log, "A quantity of oil appeared on the surface" he may feel morally certain that the pi- rates days are over but unless there is other evidence he must content himself with moral certainty. But the phrase, which repeatedly occurs in the following records supplied by the admiralty, tells it's own story.
 The following is a typical example of successful hunt by destroyers: -Four destroyers were cruising in company when an enemy submarine was sighted. Course was altered, the enemy dived, and a depth charge was dropped on the spot. After the explo- sion large dark object broke surface 90 feet astern of one destroyer. Fur thar doDtb obor1ac voro dronrod on1 soon pieces of cork and white painted wood appeared floating on the water.
 The report adds that "the position was swept and a submerged object was located" The rest is brief, but elo- quent: More depth charges were dropped when a great deal of oil came to the surface
 Another destroyer sighted peris- cope about two miles distant and headed for the enemy vessel which dived. A depth charge was dropped ''in what was guessed to be the ene- my's course" but apparently without result. An hour later, however, dull and heavy underwater explos- ion was heard" and then quantities of oil rose to the surface: but noth- ing more of the submarine was seen"
 This is how an oilship, torpedoed, in thick weather. was saved. Neither the oilship nor her escort had seen the submarine that fired the torpedo, but half an hour afterwards "an ob- ject was sighted about half a mile away" The escort at once headed for it.
 Watching for Enemy Craft.
 A round was fired, and this hit just before the coming tower Just after- wards the enemy was rammed, se- were shock being felt throughout the ship as she passed over the U-Boat. Almost simultaneously a violent ex- plosion took place. The ship now circled round under starboard helm and took up position at the place of the explosion, where the sea was boiling with foam and rushes of huge air bubbles were coming to the sur face. Oil was also observed Two men were then seen in the water, and one of them was rescued.
 The escort then returned to the oil ship and towed her into port despite all difficulties
 Sometimes patience is required to get your enemy to show himself A German submarine was believed to be lying on the bottom in a certain region, and as she would have to come to the surface to charge batteries-an operation highly dangerous" by day and therefore more likely to be under taken by night-a number of vessels were detailed to watch for her. The sea was smooth and the night dark but clear when the vessels took up their appointed positions. For long time nothing happened, but between 1 and 2 a. m. one of the vessels "gOt
