In late autumn and winter fur is absolutely essential to comfort.

Even at fifteen or twenty miles an hour the wind is penetrating and goes through everything but the closest of fur.

For women, fur or leather-lined coats are comfortable even when the weather seems still quite warm.
Leather coats are a great protection against both cold and dust.
Unhappily, most people who have no machines of their own, when invited to ride, have nothing fit to wear; they dress too thinly, wear hats that blow off, and they altogether are, and look, quite unhappy--to the great discomfort of those with them.

It is not a bad plan to have available one or two good warm coats for the benefit of guests, and always carry water-proof coats and lap-covers.

In emergency, thin black oil-cloth, purchasable at any country store, makes a good water-proof covering.
Whoever is running a machine must be prepared for emergencies, for at any moment it may be necessary to get underneath.
The man who is going to master his own machine must expect to get dirty; dust, oil, and grime plentifully distributed,--but dirt is picturesque, even if objectionable.
