OR several years we have pointed out in these columns the great advantage, to a country like ours, of the use of successful amphi- bian machines. Not only will their use avoid the tedious journeys from town to aerodrome, which must of necessity be some dis- tance away, but in many instances cities which have no suitable aerodrome, and which could only at great expense provide it, already have Another tne seSj a rjver> ol- a iake adjoining, " Milestone " wmcn makes the finest possible natural " aerodrome." So far this appears to point to the seaplane pure and simple. The amphi- bian, however, will score in many cases over the sea- plane. It can, for instance, safely make journeys over land -for distances which would be quite outside the scope of an ordinary seaplane. It is true that the carrying of the land gear entails the sacrifice of a certain amount of paying load, but on the other hand the many advantages of the amphibian machine tend to counterbalance this fact. It is a matter of great satisfaction that the Air Ministry have given evidence of their belief in the amphibian type of machine by, firstly, holding a competition for this type, and following this up by alighting tests on the Thames. The scope of the latter series of tests w7as widened considerably when, on April 29, the Vickers " Viking " left the Thames for Paris, carrying on board Col. Beatty of the Air Ministry and General Sir Frederick Sykes, Controller of Civil Aviation. The machine, which is stationed at Croydon, flew up to town and alighted on the Hard at Doulton's, near Lambeth Bridge. Leaving again at 3.30 p.m., the " Viking " arrived in Paris and alighted on the Seine at 6.20 p.m., having taken 2 hours 50 minutes for the journey. Considering that the departure and arrival occurred in the centre of the two cities, and not at aerodromes situated the better part of an hour's journey outside them, this is probably one of the fastest London-Paris journeys ever made. If a business man had been making the journey, his time from his office in London to the Paris office would have been just over three hours. We congratulate the Air Ministry, Messrs. Vickers, Ltd., and Messrs. Napier and Son, the makers of the
