Dear Mr. Robotham, Many thanks for your letter of the 29th ult., and I am, of course, quite aware of your difficulties as regards distribution. The best way to overcome this trouble when space is not available is by means of a very efficient hot spot, but of course localised as much as possible. The larger the carburetter the more this difficulty is accentuated, which is the reason that the smaller instruments do not show it on the average engine. Both the Morris and Lanchester are perfectly satisfactory, although the petrol consumption on the Lanchester is not proportionately so good as on the Morris. The latter, however, is an exceptional engine in this respect as it is quite easy to get 30 m.p.g. at 40 m.p.h. with a car weighing 28 cwts light and a 2 litre engine, which I think you will agree is pretty good. As regards trying one of your cars, I do not know if I am right but I assume you mean you would like to lend me one for a weekend. If so, I should love to try one. If I am wrong please forgive me, but your remarks relating to this are a little ambiguous. At the same time I should very much like to have one down here for a day or two to see what we can make of it. The solution of these problems is often somewhat elusive, as what is the cure for one case may be poison for another, and we find the more intelligent heads there are on the problem, the greater the likelihood of arriving at a solution.
