TEN 
chaces ; and he who then will be on the ha- 
zard-aide, must play to win the first chace; 
which if he wins by striking the ball so as 
to fall, after its first rebound, nearer to the 
dedans than the figure 1, without his adver- 
sary’s being able to return it from its first 
hop, he wins a stroke, and then proceeds in 
like manner to win the second chace, 
wherever it should happen to be. If a ball 
falls on the line with tlie first gallery door, 
second gallery, or last gallery, the chace is 
likewise called at such or such a place, 
naming the gallery- door, &c. When it is 
just put over the line, it is called a chace at 
the line. If the player on the service-side 
returns a ball with such force as to strike 
the wall on the hazard-side so as to re- 
bound, after the first hop over the line,- it is 
also called a chace at the line. 
The chaces on the hazard-side proceed 
from the ball being returned either too 
hard or not quite hard enough; so that the 
ball after its first rebound falls on this side 
of the blue line, or line which describes the 
hazard-side chaces; in which case it is a 
chace at 1, 2, &c. provided there is no 
chace depending. When they change sides, 
the player, in order to win this chace, must 
put the ball over the line any where, so 
that his adversary does not return it. 
When there is no chace on the hazard-side, 
all balls put over the line from the service- 
side, without being returned, reckon for a 
stroke. 
As the game depends chiefly upon the 
marking, it will be necessary to explain it, 
and to recommend those who play at tennis 
to have a good and unbiassed marker, for 
on him the whole set may depend ; he can 
mark in favour of the one and against the 
other in such a manner, as will render it 
two to one at starting, though even players. 
Instead of which the marker should be 
very attentive to the chaces, and not be 
any way partial to either of the players. 
This game is marked in a very singular 
manner, which makes it at first somewhat 
difiymlt to understand. The first stroke is 
called 15, the second 30, the third 40, and 
the fourth game, unless the players get 
four strokes each ; . in that case, instead of 
calling it 40 all, it is called deuce; after 
which, as soon as any stroke is got, it is call- 
ed advantage ; and in case the strokes be- 
come equal again, deuce again, till one or 
the other gets two strokes following, which 
win the game ; and as the games are won, 
so they are marked and called ; as one 
game love, two games to one, &c. towards 
TEN 
the set, of which so many of these games it 
consists. 
Although but one ball at a time is played 
with, a number of balls are made use of at 
this game to avoid trouble, and are lianded 
to the players in baskets for that purpose ; 
by which means they can play as long as 
they please, without ever having occasion 
to stoop for a ball. 
TENON, in building, &c. the square 
end of a piece of wood, or metal, dimi- 
nished by one third of its thickness, to be 
received into a hole in another piece, called 
a mortise, for the jointing or fastening the . 
two together. It is made in various forms, 
square, dove-tailed for double mortises, 
and the like, 
TENOR, or Tenore, in music, the first 
mean, or middle part, or that which is the 
ordinary pitch of the voice, when neither 
raised to a treble, or lowered to a bass. 
The tenor is commonly marked in thorough 
bass with the letter T. This is that part 
which almost all grown persons can sing; 
but as some have a greater compass of 
voice upwards, others downwards, others 
are confined to a kind of medium, and 
others can go equally high or low ; hence 
musicians make a variety of tenors, as a 
low, a high, a 'mean, a natural tenor, to 
wdiich may be added, a violin tenor, &c. 
for instruments. 
TENSE, Time, in grammar, an inflec- 
tion of verbs, whereby they are made to 
signify, or distinguish the circumstance of 
time, in what they aflirm. 
TENSION, the state of any thing 
stretched as a'line, &c. Tims animals sus- 
tain and move themselves by the tension of 
their muscles and nerves : a chord, or mu- 
sical string, gives an acuter or deeper sound, 
as it is in a greater or less degree of tension, 
that is, more or less stretched. 
TENT, in surgery, a roll of lint worked 
into the shape of a nail, with a broad flat 
head. 
TENTER, a machine used in the cloth 
manufacture, to stretch out the pieces of 
cloth, stuff. See. or only to make them even, 
and set them square. It is usually about 
four feet and a half high, and for length ex- 
ceeds that of the longest piece of cloth. It 
consists of several long pieces of wood, 
placed like those w’hich form the barriers of 
a manege ; so that the lower cross piece of 
wood may be raised or lowered, as is found 
requisite, to be fixed at any height, by 
means of pins. Along the cross pieces, 
both the upper and under one, are hooked
