5. Tests should be carried out to see whether if the engine is turned faster it will start up better when cold.

At present with the engine and battery very cold, say about 15°F.{Mr Friese}, the engine is only turned at 20 to 25 R.P.M. At that low speed we believe a lot of the compression leaks away and for this reason we do not get sufficiently vigorous explosion for the engine to start.

6. In order to obtain equal results from the batteries out here in cold weather, as we get in England, we should expect that a larger battery is necessary to suit American conditions.

7. Cars develop rattles out here much more rapidly than they do in England.

4-EX Car had run 12,000 miles in England without giving any trouble in this respect, but after 3,000 miles over here there is considerable noise coming from the bonnet.

I should like to emphasize the fact that these suggestions for modifications are only necessary in order that the Rolls-Royce car shall perform under conditions existing here, in the same way as it does in England.

It has already been proved that the steering, which has been quite satisfactory in England, needs modification to suit this country.

With regard to the springing, it has been found that different conditions existed.

We are now finding that under winter conditions, and the quality of petrol, other modifications are necessary.
