MAY 27, 1920 gear and wireless cabinet. Aft of this, two or more pairsof wing cars are fitted at varying distances from the centre hne of the ship to prevent the slipstreams of the forwardtars blowing on to the after units, thus increasing head re- sistance. On the landing ground, the ship would generallybe supported at its forward end by the control car, and at the after end by a pair of wing cars. In certain cases howeverthe control car is fitted so far forward that it is always well off the ground, in which case the bow of the ship issupported on the landing ground by the forward pair of wing cars. ° The present tendency in England is to regard this systemas the more efficient. In the first place, the overall height of the ship can be appreciably reduced. In the Zeppelin typethe overall height must be about 13 ft. more than the maximum diameter. In the British arrangement, it is possible to bringthe overall height down almost indefinitely, so that in an extreme case it would be no greater than the maximumdiameter of the hull. In practice, however, it is desirable" to fit the cars in such positions that the hull is always kept atsome 5 or 6 ft. above the ground to allow for inequalities in the surface of the landing ground which might otherwisedamage the hull structure while handling the ship on the ground. The reduction, however, of some 7 ft. in overallheight compared with the Zeppelin system is, in practice, of considerable importance, due to the small size of exisitingshed1 accommodation. A third advantage is that the wing power cars, probably owing to their small size, are moreefficient then the larger centre line cars. This is especially the case with the large forward centre line car, which, as hasalready been stated, contains, besides the power car, a wireless * cabinet and control car, and the resulting composite car is ofnecessity of such size that it somewhat blankets the propeller. In the case of the R 33 class, the lack of efficiency in the aftercar is probably to some extent due to the fact that it contains two engines and is of bad streamline form. In the British system each car is used for its special function,and there is no loss of efficiency due to make a compromise. In this way each power car can be exactly the same, and only theslinging arrangements need be slightly varied. It seems probable that for many years to come the ma-chinery installation will be the mbst unreliable part of the ship during flight, and will, besides, require the most frequentoverhauls and renewals. It is obviously equally important that both service and commercial rigids should be laid up fora minimum number of days per year and not for long periods as heretofore while their machinery is overhauled. Provisionshould^ therefore, be rapidly developed whereby the power cars, as complete units, can be rapidly changed. No reasonis seen, in the future, why such units cannot be so simplified that it will be possible,' without actually takingthe ship into the shed, to change one or more of the complete* units. Besides providing standard power units, the separateparts such as the engine, transmission gear, etc., should be designed to be rapidly replaceable by new standard parts.Too great emphasis cannot be laid on the importance of standard power units.

Air Work in Russia IN the Bolshevist military report of May 19 it was stated :— " Black Sea Front.—In the Sea of Azoff two enemy war- ships opened fire on the fort of Temriuk town, correcting their gunfire by the help of three aeroplanes. After our artillery answered their fire they made off in a north-westerly direction." In the Bolshevist report of the following day the following appeared :— " Our troops were assisted in crossing the River Beresina by a squadron of our aeroplanes, which bombed the enemy's positions. In the Vapniarka region .... we captured an enemy aeroplane which had been brought down." The Polish report issued from Warsaw on May 21 stated :— " North of the Dniester the enemy re-attacked Krzyzezopol. Our infantry however, supported by a squadron of aeroplanes, counter-attacked brilliantly and forced the enemy back for a distance of 12$ miles." Independent Air Force R.A.F.

Voluntary Hospitals Closed AT a recent meeting j>f the general committee of the Royal Air Force Voluntary Hospitals it was resolved that thisorganization should come to an end. Since 1915 the com- mittee, with the patronage of Princess Christian and underthe chairmanship of Sir David Henderson and later of Sir Thomas Berridge, has raised upwards of £120,000 for equippingand running hospitals and convalescent homes for officers of the Royal Air Force, nearly 5,000 of whom have receivedtreatment during the past four years. The surplus funds will be handed over to the Royal AirForce Memorial Fund Committee, formed on the initiative of Air Marshal Sir Hugh Trenchard, under the Presidency ofPrince Albert, to be applied for officers and men of the Royal Air Force who may be disabled, sick, or otherwise infirm,and the hon. treasurer, Mr. Walter S. Field, will join this latter body to represent the funds. Cricklewood Aerodrome Award MR. EDWIN SAVILL, the arbitrator appointed to considerthe claim of the Ecclesiastical Commissioners for £43,575 against the Ministry of Munitions in respect of the compulsoryacquisition by the Ministry of the land on which the Crickle- wood Aerodrome is built, has issued his award. It is to theeffect that the amount of purchase money and compensation to be paid by the Ministry to the claimants for the purchaseand for damage, injury, and loss suffered by reason of severance of such purchase land from the other lands, shallamount to £31,320. It was arranged that the question of costs should not be dealt with in the award, and it istherefore reserved. 581
