The difficulty, however, was in the coil.

Apparently the motion of the vehicle had worn the insulation through at some point inside.

The new coil, a common twelve-inch coil, worked well, giving a good, hot spark.
The farmer who had so kindly pulled the machine in the day before would accept nothing for his trouble, and was, as most farmers are, exceedingly kind.

It is embarrassing to call upon strangers for assistance which means work and inconvenience for them, and then have them positively decline all compensation.
The ride into Worcester was a fast one over good gravel and macadam.
Immediately after luncheon we started for Boston.

Every foot of the road in from Worcester is good hard gravel and the ride is most delightful.
