Meat scraps are relatively coarse
dry material of varying proportions
of flesh, bone and fat. During the
summer months lots of tainted scraps
are frequently found. Preference

The 16 samples reported have been
divided into first grade-those testing

second grade--those testing below As
per cent. protein. The IL first grade
scraps averaged SLOT protein, 1929
fat, and 22.43 ash, and the average
retail price was 1888 a hundred. The
second grade scraps averaged 4l.09
protein, 14.47 fat, and 1884 ash; the
average retail price was $40 hun
dred. These scraps contained more
bone and less meat than the first
grade. The station cannot recon-
mend any particular brand.
Meat and Bone Meals are not so
freely offered as meat scraps. They
are dry, finely ground, contain less
meat and fat and noticeably more ash
than do the scraps. To be of first
grade, they should contain 40 per
cent. protein, ten per cent, fat, 40 per
cent. ash, and be free from bad odor.
They are worth in the vicinity of 20
per cent. less than first grade scraps,
The nine samples reported have been
divided into first and second grades,
depending upon the protein per cent
Bone Meals, few samples Of which
were collected, have been made from
either kettle rendered bone, or from
bone steamed under pressure. The
latter contains less protein, and can
be sold at little lower price. Two
samples collected fell decidedly below

the nutrients needed, and that in some
cases were put together as cheap

price was about $1.75 hundred
pounds, whether they contained much
or little protein and ash.
