Lord mahon’s Method of fecuring , See. 881; 
(either of oak or fir) fhould be nailed againft each fide of 
every joift, and of every main timber, which fupports 
the floor intended to befecured. Other fimilar laths ought 
then to be nailed the whole length of the joifts, with 
their ends butting againfi each other: thefe are what I 
call th e fillets. The top of each fillet ought to be at one 
inch and a half below the top of the joifts or timbers 
againft which they are nailed. Thefe fillets will then 
form, as it were, a fort of fmall ledge on each fide of all 
the joifts. 
§ 3 , When the fillets are going to be nailed on, forae 
of the rough plafter hereafter mentioned (§ 9.) muft be 
fpread with a trowel all along that fide of each of the 
fillets, which is to lay next to the joifts, in order that 
thefe fillets may be well bedded therein when they are 
nailed on, fo that there fhould not be any interval be- 
tween the fillets and the joifts. 
§ 4. A great number of any common laths (either of 
oak or fir) muft be cut nearly to the length of the width 
of the intervals between the joifts. 
Some of the rough plafter referred to above (§ 3.) 
ought to be fpread, with a trowel, fucceflively upon the 
top of all the fillets, and along the fides of that part of 
the joifts which is between the top of the fillets and the 
upper edge of the joifts.
