| -3- The spring withdrawing ring on all 6 wheels were loose. It will be recollected that during the test one of these 17 rings came off and caused great difficulty in removing the wheel. Water was found inside the rims when the tyres were removed. Apparently this was of no detriment to the tyres 18 during the 23 days (the period in which the trial took place) but it might be detrimental over a longer period. Water apparently finds its way through at the gap in the split detachable flange. 19 Bonnet Fasteners. - The offside front bonnet fastener seized in its guide, due to lack of lubrication. There is no mention of lubricating these parts in the instruction book. We suggest a few drops for every two thousand miles. 20 Petrol Tank. - There are signs of rust commencing to appear at the bottom of the tank, almost as though the galvanizing is not sufficient protection. We have a number of cases of corrosion eating right through the tank on cars made about 1913 and 1914. The small filter in the petrol tank is 21 partially choked with sediment, and it would appear to be advisable to take it out, wash it by removing it, and turn it upside down every 10,000 miles. A short description of the operations necessary to carry out this work could be given to advantage, and included in the instruction book. 22 Lucas Dynamo. - This was the second dynamo fitted to the car during the 10,000 miles run. This dynamo has done about 8,000 miles. There is an appreciable amount of slack in the ball bearing, also the wear on the commutator appears to be excessive for this mileage. The remainder of the electrical parts are in first class condition. 23 Hartford Shock Absorbers. - The friction of the Hartfords has increased in one case from 40 lbs. to 87 lbs. and in the other from 40 lbs. to 47 lbs. The wooden bearings have swollen, and are very difficult to move. Both these features are of fairly common occurrence on cars, and completely spoil the riding of the car at slow speeds. Hm.{Capt. W.
