WESTFIELD, NEW JERSEY.

Your nice paper comes with mamma's. We have had lots of fun with

the "Wiggles." Won't you please answer this question: In our

dining-room there is a big looking-glass. In front of the glass

there is a table. When a lamp is set on the table, it looks as if

there were two lamps. Please tell me whether the lamp on the table

and the one reflected in the looking-glass will give as much light

as two lamps.
