READING IN RAIL CARS.

Reading while in the rail cars or in omnibuses is to be avoided. The

rapid shaking, trembling or oscillating motion of the cars makes it

very difficult to keep the eyes fixed upon the words, and is very

tiresome. I have seen many persons who attributed the failure of their

eyes to the daily habit of reading while riding to and from the city.

Children should be cautioned against reading with the head inclined

forward. The stooping position encourages a rush of blood to the head,

and consequently the eyes become congested, and the foundations for

near-sightedness are laid.
