Four special reasons have operated to increase the difficulty ot the navies of the Allies in combating the menace of the submarine. They are: First, the construction of larger U-boats and a great speeding-up of tlie rate at which they arc being set afloat; second, the transference of the field of operations from the shallow waters of tho North Sea and the Channel to the deep waters of the Atlantic; third, the construction of pairs of submarine mother-ships of, it is said, over 2000 tons displacement, which are believed to act with groups of fighting U-boats on certain definite stations, one moth-er-ship serving as a receiving ship for the resting-up of tho U-boat crews, and the other as a supply ship for furnishing oil, torpedoes, and sliolls to the fighting craft; fourth, tho thorough organisation of those deep-sea. operations along clearly-defined strategical and tactical lines, with the object of covering all the avenues of approach to and departure from Europe, and of establishing a fairly continuous line of blockade by independent, selfsustaining squadrons of U-boats.
