Half an hour went by before Jane felt quite sure that they could none of
them spell Psammead. And they could not find it in the dictionary
either, though they looked. Then Jane hastily finished her letter--

"We found a strange thing, but it is nearly
post-time, so no more at present from your little
girl,

"JANE.

"P.S.--If you could have a wish come true what
would you have?"

Then the postman was heard blowing his horn, and Robert rushed out in
the rain to stop his cart and give him the letters. And that was how it
happened that, though all the children meant to tell their mother about
the Sand-fairy, somehow or other she never got to know. There were other
reasons why she never got to know, but these come later.

The next day Uncle Richard came and took them all to Maidstone in a
wagonette--all except the Lamb. Uncle Richard was the very best kind of
uncle. He bought them toys at Maidstone. He took them into a shop and
let them all choose exactly what they wanted, without any restrictions
about price, and no nonsense about things being instructive. It is very
wise to let children choose exactly what they like, because they are
very foolish and inexperienced, and sometimes they will choose a really
instructive thing without meaning to do so. This happened to Robert, who
chose, at the last moment, and in a great hurry, a box with pictures on
it of winged bulls with men's heads and winged men with eagles' heads.
