Some amateurs, in developing, have three trays of developer. The first
tray contains normal developer, the second tray contains developer
prepared for over-exposed plates, and the third for under-exposed
plates.

If a plate is found to be under or over exposed, it is washed and
removed to the tray containing the proper solution. This is a very good
plan if one has a quantity of plates to develop which have been exposed
at different times and under different circumstances, as it saves
preparing fresh developer after development has been started.

SIR KNIGHT FRANK KANE asks what is meant by a flat negative. A
flat or thin negative is one which has been over-exposed, and not
sufficiently developed to give the necessary density, so that the
light passes through all parts quickly, and gives a flat picture,
wanting in contrast. The next number of the ROUND TABLE will give
methods for strengthening or redeveloping thin negatives.

A RAINBOW TEA.

BY MARY J. SAFFORD.

Suggestions for pretty effects at church fairs are always in order, and
one which I attended recently was so attractive in its arrangements, and
so well carried out in every detail, that a description may be of
service to those who are planning a sale.

Even the tickets were in harmony with the remainder of the decoration.
They bore diagonally across the centre, the upper left-hand and the
lower right-hand corners, a rainbow, while the lettering ran:

RAINBOW TEA.

Entering the room one saw directly opposite to the door the seven
tables, each representing one of the colors of the rainbow. All were the
same length and width, covered with the pretty, inexpensive crepe cloth,
and bordered with a frill of crepe-paper the same shade. From the end of
each table ran a width of the crepe cloth, through whose centre was a
strip of satin ribbon the same shade about four inches wide. These
extended to a small square table and fastened on the top. This table was
placed midway between the red and the violet one, which stood on the
same line, perhaps six feet apart, the other five tables being set
between in the order of the colors of the rainbow, the green at right
angles with the red and the violet, and the remainder slanting. The
