may be obtained. "One quarter" of fifteen is one stroke given at the
beginning of the second, sixth, and every fourth game thereafter in the
set. "Two quarters" (the "half fifteen" spoken of above) is one stroke
at the beginning of the second, fourth, sixth, etc., games. "Three
quarters" is one stroke at the beginning of the second, third, fourth,
sixth, seventh, and eighth games, and so on. When it is "odds owed," as
before, "one quarter" is one stroke in the first and fifth games; "two
quarters" is one stroke in the first and third; and "three quarters" is
one stroke in the first, third, and fourth games, and so on to the end
of the set. In order to get odds at a similar ratio when the match is
being scored on the "100-up" system, the following table of equivalents
has been adopted:

1 quarter of 15 = 5 points per 100
2 quarters " 11 " "
3 " " 16 " "
15 " " 22 " "
15.1 " " 27 " "
15.2 " " 32 " "
15.3 " " 38 " "
30 " " 43 " "
30.1 " " 49 " "
30.2 " " 54 " "
30.3 " " 59 " "
40 " " 65 " "

The principal difficulty about this new system of odds, except for
experts and for those who play constantly, is the difficulty of
remembering it. It certainly takes more study to become familiar with it
than with the old half-point system. In that the odds change at every
game, and change directly back again even when most complicated, so that
really all there is to remember is which odds came with the service. The
chief advantage of the "quarter" system is that it affords greater
accuracy, and to experts this is a sufficient compensation for its
intricacy. I should not advise the average player, however, to bother
with it, for, unless he intends to try for a national championship, life
is too short to devote many hours of study to the "quarter" system.

Another correspondent asks for information as to the best way to get up
a tennis tournament, and now that we are on the subject of tennis, his
query might just as well be disposed of. A tournament, like anything
else, demands time and care in preparation if it is to be a success.
Don't put off everything until the last moment, or the day will surely
be a failure; whereas, if thought is given to all the small details that
go to make such an occ
