The complaint of pitching at high speed has been cured, but the complaint of dithering, which is an old complaint and quite as serious as pitching, is very pronounced. what is very noticeable with it is that the car continues to dither at high speed up to 60 and 65 M.P.H. 25-WJ, our demonstration car, pitches badly at high speed, but of the two, I much prefer 25-WJ to 25-EX. I do not like the steering, the defect being that on high cambered roads at high speed it is extremely difficult to steer the car at all and on sharp bends the speed of the car had to be reduced to 20 M.P.H. otherwise the back of the car commenced to skid across the road. Today, Henning has been here with 31-GX and I have tested it. I consider this car as near perfection as possible for continental conditions and in my opinion there would be comparatively few complaints if the springing of cars used on the continent were as good as this.
