cut tints skilfully. Kemember that future 
success depends upon the manner in which 
these first lessons are cut. When able to 
cut tints well, take a small picture which 
is made principally of tints. In a drawing 
on wood, the lines to express the given 
effects are cut according to the judgment 
of the engraver. In a transfer, all the 
only those that have sharp and regularly 
cut teeth. No.'s 0,00, and 000, are very 
small and fine, and are used only for the 
finest of work, such as inlaying, cutting 
the veins of leaves, or turning small circles. 
The saws numbering from one to six are 
the best sizes for general work, as the 
smallest can be used for nearly all pur-

lines are transferred to the wood just as 
they are to be cut. Hence transfers, at 
this stage of the pupil's progress, are 
most serviceable for practice. 
Scroll Sawing— III. 
BY F. T. HODGSON. 
BY an examination of Fig. 12, it will be 
seen how saws are graded for sizes ; 
they can be bought for about ten cents a 
dozen for the cheaper sort, and from 
twenty to thirty cents a dozen for the best 
qualities. 
' In choosing saw-blades, it is best to take 
poses of fine work, and the largest is 
strong enough for any work the amateur 
will care to undertake with a saw operated 
by hand. The finest saw blades have teeth 
so fine that they are scarcely visible to the 
eye, and naake a cut or " kerf" so narrow 
that a slip of the paper of this book would 
fill it ; they require no set, and are never 
sharpened, and can be used until they get 
broken, which is their natural end. For 
hand sawing the numbers 0 and 1 are the 
best sizes to use, unless very delicate work 
is required, when the finer numbers may 
be employed. 
As before stated, the capacity of the
