grown at IIighmoor Farm during the past
three years reveals many interesting
facts relative to the variability in per
cent of protein. carbohydrates ana fat
in this plant.
Among the varieties of oats tested in
1910 there are. marked differences IN the
composition Of the grain. The percen-
tage OF protein varies from 1885 per cent.
TO 1874 per cent. and the calculat'
yield of protein ranges from PAS TO rs
pounds per acre Tile percentage IF
Carbohydrates ranged from 57.11 per cent.
Ia G9M per cent, and the yield Of en-
borhydrates carried from 90s pounds 20
400 pounds per acre. The percentage 4

varies from 3.94 per cent. to Us Ter
cent. giving a yield of G. to 1f3 pour Is
per acre These l6 varieties OF O u
Yielded from 461 bushels to 49, bush,
per acre.
Among "A varieties of oats tested in
1911. of which 10 varieties were in the
tests of 1910 similar variations in COM
position exist The percentage Of pro-
tcin ranges from l432 per cent. To 1905

acre varying from 206 10 POI pounds. The
| Percentage of carbohydrates varied from
| ID per cent. to eli per cent. and the yield

pounds per acre. The percentage of fat
varied from - per cent to s.5 per cent,

per acre The yield of these Il varieties
grown In 1911 ranged from 81 bushels to

than the season of 1910 to the growth of
1 oats.
| These analyses show that there are
strains of oats containing a high per-
| centage of protein while other strains
| run low in protein. The percentage OF
| carbohydrates. however. does not vary
quite as much in the different varieties
| as does the percentage of protein. 1t is
| noticeable from the data collected In the
| two years cited that strains Of oats do
| not differ much in composition from sea
| son to season. That is. n variety con
| tanning a high percentage of protein in
| 1910 also shows similar proportion in
| 1911. For example the crop of Presi-
| dent oats grown in 1910 contained
IL per cent of protein, the crop in 1911
| contained GIG per cent of carbohy-
drates; in l91i GO 81 per cent. The va
| riety of oats which contained the
highest percentage of protein. name
| ~ 1914 per cent in 1910 was the
Early Champion. This Dat contained 1906
per cent. protein in lthe 1911 crop. The
Early Champion contained So per cent.
of carbohydrates in 1910; 57,4 per cent. in
1911.
1t is clear that an DAT may he a high
producer measured in bushels of grain
centage of protein. However, some of
the varieties in the tests made at High
| moor during the past three years are
high producers of grain and also give a
comparatively high yield of protein per
| acre. For example, the variety which
yielded the most grain per acre Ci33
bushelsl in 1910 gave the largest amount
of protein, namely 426 pounds. This
variety of oats, according to analysis,
| contained 1872 per cent. protein.
| From the above figures we must realize
the variability in composition that exists
i between varieties of oats. This is of
considerable value to the farmer 1t sug-
