(/ycss MODELS. MR. K. W. POTTS, a model worker who works on carefully thought out lines and keeps a full record of all his experiments, has sent us the following notes on tuning up a model aeroplane, tractor type, explaining his method of proceeding :— " i. Having built up the model, place it on a level table and carefully measure the height of each wing tip from the table surface. Adjust them till the measurements are exactly the same, ensuring at the same time that the chassis is perfectly square and rigid with the fuselage. (If the model is a purchased one the position of the main planes should be marked ; fasten same securely.) "2. Measure tail in a similar manner, and adjust till level, at the same time seeing that the skid keeps the tail at least one inch off the table. " 3. See to fin, adjust till it is at right angles with the fuselage, and perfectly square when looking from the tractor. "4. Lubricate elastic and tractor bearing, adjust elastic taking care that it is not too tight. "5. Wind up elastic to one row of knots, hold model, see if it stands square, and, still holding model, let tractor revolve. " 6. The model should now be tested in the open air. Choose a smooth piece of ground with plenty of room all round. Place model facing the left of the wind, wind up one row of knots, let model taxi over ground and observe how it runs, adjust fin till the model runs straight. Afterwards wind up about IOO turns short of the full number, let the model fly a short distance and adjust as required. If the model does not rise move the main plane forward ; if the rise is too fast, move the main plane back. These adjust ments should not be more than s\ of an inch at a time. '• 7, When finished flying, take elastic off, and keep it in the dark. Always lubricate both elastic and bearing before flying." ® ® ® ® Anti-Aircraft Insurance for Small Properties. IN the House of Commons on Wednesday Mr. Herbert Samuel, Postmaster-General, announced that with the concurrence of the Board of Trade a scheme had been framed by the two departments, which would enable members of the working classes to effect, through the Post Office, insurances on properties of comparatively small value against air raids and other risks. Any member of the public will be able to apply at the counter of any post office for a certificate of insurance, and on filling in his name and address on the certificate and counterfoil and paying a sum of 6d. his property will be insured by the Government to the amount of £2$, for a period of 12 months, against destruction or damage directly or indirectly caused by attacks by aircraft, or by shells used against aircraft, or by bombardment from the sea. A payment of if, will effect an insurance of ^50, and of ir. 6d. an insurance of ,£75, which is the maximum amount. Insurances for .£100 and over can be effected under the previous Government War Risks Insurance Scheme. The Post Office insurance is not intended for property worth more than £100, nor does it apply to buildings, nor to loss of life or bodily injury. In the event of damage covered by the insurance, claims may be made through any post office and will be dealt with by the Government War Risks Insurance Office. In an explanatory pamphlet it is stated that the property insurable includes furniture, clothing, household goods, tools, and personal effects ; stock, fixture fittings, and utensils of trade. The amount paid will be limited to the actual amount of damage done, and even if several certificates have been taken out on the same property not more than £75 in all will be paid. If the loss is covered by other insurance the first claim must be paid upon them, and no payment will be made by the Government unless the amount paid by the other insurers is insufficient to meet the amount of the damage done. The useful average clause will prevail, that is to say, if £30 damage is done to property insured for £7$ and worth <66o> £TS> £80, or ,£ioo, the full loss will be paid. If the property were worth ,£150 only two-thirds of the damage (^20) will be paid. Firing on Zeppelins. QUESTIONED in the House of Commons on the 3rd inst., Mr. Tennant said it was not the case that orders to open fire can only be given by a field officer. Any officer may order the troops to fire. The Lights of London. REPLYING to a question in the House of Commons on Tuesday, Sir J. Simon, Home Secretary, stated that the lighting of London was regulated in accordance with advice given by those responsible far the defence of London from air raids, and while full consideration was given to the desirability of maintaining reasonable lighting he could not disregard the advice under which he was acting. The matter was receiving close attention, and if any relaxation was found practicable it would be given effect to without delay. NOVEMBER 12, 1915. Anti-Aircraft Defences. ME. LYNCH on Tuesday addressed a question to the First Lord of the Admiralty as to whether efficient range-finders for Zeppelins had been provided in London for the use of the anti-aircraft service. Dr. Macnamara replied that it would not be in the public interest to publish details of the defences of London against aircraft. Mr. Lynch : Does not the right hon. gentleman's inability to reply to the question really mask grave incompetence on the part of this Dt-partment ? Dr. Macnamara : No, the answer means what it says. New Works for Emaillite. As will be seen from an announcement elsewhere in this i sue, the British Emaillite Co., Ltd., are now in tailed in their new works at 5, Hythe Road, Cumberland Park, Willesden Junction, N.W. Already the productive capacity of the new plant has been fully tested, and it is gratifying to hear that the demand for Emaillite, still continuing on the up-grade, has necessitated the laying down of numerous new machines. An Industrial Opening. IN our advertisement columns this week appears an announce ment on page xi inviting enquiries in regard to taking up the con struction of a new British warplane. It should afford a unique opportunity for any capitalist who is desirous of entering the aeronautical industry with a tried article ready for exploitation to his hand, and it is for this reason that we draw attention to the matter. ® ® ® ® Exports, Re-Exportation. 1914. 1915. 1914. 1915-£ £ £ £ 210 435 879 13,706 106 138 1,934 7,218 1,17s 23,986 4,059 12,530 5,082 3,730 142 2,400 4,994 13.372 1,695 630 36,276 910 — 4,908 — 325 17,702 441 18,823 1,440 5,090 1,473 275 9,484 8,250 247 Imports. 1914. 1915. £ £ January ... 5,945 20,382 February 28,132 380 March ... 27,731 280 April ... 11,384 2,189 May ... 17,062 178 June ... 15,967 5,469 July ... 15,548 1,240 August ... 52,448 664 September 4,859 536 October... 39,287 1,344 218,363 32,662 ® NEW COMPANY REGISTERED.
