The next lesson, which is not quite so simple, is that some of these points belong exclusively to trams going one way and some exclusively to trams going the other.

If there is one thing calculated to reduce a perplexed foreigner in Amsterdam to rage and despair, it is, after a tiring day among pictures, to hail a half empty tram at a fixed point, with _Tram-halte_ written on it, and be treated to a pitying smile from the driver as it rushes by.

Upon such mortifications is education based; for one then looks again more narrowly at the sign and sees that underneath it is a little arrow pointing in the opposite direction to which one wished to go.

One then walks on to the next point, at which the arrow will be pointing homewards, and waits there.

Sometimes--O happy moment--a double arrow is found, facing both ways.
It is on the Dam that guides will come and pester you.
