ADDITIONS TO COSTS TABLES TO COVER INCREASED EXPENSES
CONGRATULATTONS on reverting to the publication of your journal on Fridays. I feel sure that your readers will greatlyappreciate this.
I am proposing to the South-Eastern Regional Commissioner, upon whose Advisory Committee I sit, that the time and mileage charges given in your valuable operating costs should be employed for a certain purpose.
I realize that as things are in such a fluid state it would not be possible to issue completely revised Tables of Costs for publication just'now, but it occurs to me that it would be of the greatest possible assistance to your readers if an approximate percentage figure could be added to those in the Tables to cover war-time
increases and expenses. A. C. NORMAN, Brighton. for The Southern Transport Co., Ltd.
[We, are pleased to learn that our change of the day of publication of this journal is satisfying our readers. As regards the increases to be made on the figures for operating costs which we published before the war, we suggest . that the following would be approximately correct:20 per cent, to time charges. 33 per cent, to mileage charges for petrol vehicles, and 25 per cent, to mileage charges for those with oil engines.—En.]
COOLING A CAR ENGINE FOR TRACTOR WORK 1 HAVE converted a Chrysler 25 h.p. car into a tractor for land work, the difficulty is, however, that the cooling water boils in warm weather, although it is all right if there be a good breeze. Would an additional fan, outside the radiator, which can be driven by belts' and shaft, be worth fitting, or is the ordinary fan designed to suck enough air through the radiator to keep
the engine cool? A. WRIGHT. Hesketh Bank.
[We suggest that your problem would probably be solved by the addition of a big-capacity fan in the manner you suggest. You may find that this alone will be sufficient and that you can disconnect the standard fan, but this must be determined by experiment. Actually, a better scheme would be to replace the existing fan by a large fan on the inside of the radiator, but it is probable that this cannot be done. Have you checked up that the watercirculation system is functioning properly? It may be that there is something wrong here, or, indeed, something other than that wrong with the power unit.—ED.]
