THE YOUNG SCIENTIST. 
"by calculating from twelve to sixteen, or 
twenty stitches, and taking coarser wool. 
Also more diversity may be introduced 
into the coloring by the blending of 
several contrasting hues, or the artistic 
shading of one color, from the lightest to 
the darkest shade, and vice versa. Even 
stitch, pick up and knit seven stitches 
along the opposite side, which will bring 
you back to the twenty-four stitches. In 
raising the loops, take up the back part of 
every other stitch. Leave this needle un- 
touched. The first triangle is complete ; 
proceed to the following one by knitting 
Fier. 2. 
when executed in a single tint the blocl^s 
can disi:>lay change, by intermingling 
^vitli the plainly-knitted checks others of 
purl, ribbing, moss-stitch, etc. To work 
the pattern, take any number divisible by 
eight, according to the size required. For 
the four checks of the illustration cast on 
thirty-two stitches, and set them, if for 
large work, by one plain and one purled 
TOW. 1. Half squares.— Knit plain, with 
the darkest color, eight stitches; leave 
the remaining twenty-four aside, turn the 
■work, and with a third needle purl back, 
taking the last two stitches together. 
IRei>eat this at every alternate row, till 
there is but one stitch left on the needle. 
'Thus In the third row you will knit seven, 
in the fifth row six, in the seventh row 
iive, in the ninth row four, in the eleventh 
TOW three, in the thirteenth row two, in 
the fifteenth row one. Your reductions 
liave been made on one side only. Now, 
with the needle which bears the one 
off eight more loops, and decreasing them 
as before; pick up the stitches of the 
straight side again, leave them on the 
needle, and continue in the same way to 
make two more triangles with the sixteen 
remaining stitches. 
Second row. Complete squares. — The 
first row has produced four triangles, on 
each of which has been left a needle hold- 
ing eight loops. These sets of loops form 
the foundation of squares which, sloping 
in a reverse direction, fill up the spaces 
between the triangles. They are likewise 
made separately, and joined to the side of 
the half-squares whilst working. Pro- 
ceed thus:— With contrasting wool, purl 
the eight loops of either the first or the 
third triangle; it does not signify at 
w^hich end you commence. Knit back 
seven of the stitches ; then slip the last 
loop off on to the needle already full. 
With the needle now at liberty, lift up the 
back part of the first stitch on the de-
