It would appear therefore that there is a definite local strain taking place at this particular part. We have tried to prevent this by paying special care to the sliding joint and the stays with the moving back of the crossmember for the diamond mounting of the engine, it has left the silencer unsupported at the front end. This is detrimental to the free working of the sliding joint. The rear silencer lagging has torn away from the bands holding same to silencer. It has also crept forward and the joint opened out. The condition is very poor. The swanneck and snout have remained in good condition. There has been no failure of any of the brackets.

FAN to LOP.E.56250 - Lec.2921.

To suit Engine Suspension with Dropped Radiator.

We have had no further trouble with the fan blades becoming loose after paying attention to the rivets, as previously reported. The trouble in the first instance was most probably due to the rivets not being firmly snapped up, as we have not had any previous trouble of this kind with this design of fan. The second Dunlop fan belt which we fitted after the breakage of the first, has shown no sign of weakness during the remainder of the mileage. Messrs Dunlops' report that the failure is due to the fan belt being too tight in the first instance, and the sudden acceleration breaks down the core of the belt.

RADIATOR & FITTINGS to LOP.E.56831 - N.S.3313.
RADIATOR SHUTTERS to LOP.56829 - S.S.3312.

Radiator Dropped 4" in Frame.
E.57000 Bottom Tank.

With the exception, as reported at 8,000 miles, of the one occasion, when we had a water temperature of 100°C with a following wind, we have had no trouble with high temperatures. A slight water leak has developed in the bottom O.S. at the joint of the tank, by the matrix. The leak being very small, loss of water has not been noticeable. The thermostatically operated shutters stuck on one occasion during the latter part of the mileage, after starting up from cold, which caused the water temperature to rise to 100°C for a short period. They opened up however, and the temperature quickly dropped to its normal average temperature. This has only happened once during the whole mileage. No serious loss of water has occurred during any one of the daily runs.

BONNET to LOP.E.56820.

The bonnet has remained in good condition. We have had no farther trouble, as reported, with the bonnet side jumping out. We have not had the high air temperatures to obtain the beneficial results of the bonnet shutters. We however obtained the following tests. At a speed of 40 MPH with an average air temperature of 19.3°C, the difference
