INTRODUCTION.
“The most significant fact in the educational world to-day is the
demand that agriculture be taught in the public schools. * * * I
do not believe in that philosophy of education which would establish
separate schools for the various industries and occupations of life.” *
If we accept these statements, the conclusion is obvious: we should
teach agriculture in existing high schools and we should do it now.
We should teach this subject in existing schools because:
1. We are not ready to establish separate industrial or trade
schools in this country. Such schools, if maintained at state expense,
smack of European conditions and class distinctions.
2. We could not meet the expense of a dual system of secondary
schools, even if we were willing to do so. Most districts find some
difficulty in providing adequately for existing schools. To divide our
energies and resources between two systems of high schools, would
mean the ultimate failure of both.
3. The existing high schools can easily be made to fill the de-
mand. When agriculture is put on an equal footing with other sub-
jects, when teachers are employed who know and can teach the sub-
ject, and when they are given time and equipment to teach it, the
problem will be solved.
4. Measured by any standards of educational aims and educa-
tional values, courses in agriculture will compare favorably with
other courses taught.
We should introduce this subject immediately, for the very excel-
lent reason that the demand must and will be met. Some states have

4 INTRODUCTION
already waited too long and as a result now face the problem of a
dual system of high schools. Certainly no greater misfortune than
this could befall the public schools cf any state.
It seems to me that the growing demand of our people that the
echools be brought into closer relationship with the life of today;
that the courses of study take into account, in some measure at least,
the dominant interests of the community; that, among other stand-
ards of selection, we give some attention to the immediate interests
and future prospects of our pupils; is not only fair and just, but is
eminently sound pedagogy. If so, then the immediate problem con-
fronting all of us who are interested in secondary education is, how
to organize this course, how to fit it into the curriculum and how
to teach it so as to secure its maximum educational value to our
pupils. It is in the hope that I may contribute something to the
solution of this problem, that this book is written.
In the preparation of the book many sources of information have
been drawn upon, but the plan is original. I am especially indebted
to Dean F. B. Mumford, Professor J. C. Whitten and Mr. C. B.
Hutchison, of the College of Agriculture, for valuable suggestions
and corrections; and to Professor J. H. Coursault, of the School of
Education, for reading the proof. ‘J. D. ELLirr.

PURPOSE AND PLAN.
The teaching of agriculture in the high schools is beset with
many difficulties, among which are the following:
1.. Scarcity of trained teachers.
2. But few good high school texts.
3. A frequent misconception of the purpose and value of the
course on the part of teachers and parents.
4. Confusion of pupils and teachers due to the wide variety of
suitable topics that may be studied and the great abundance of
illustrative material.
5. The still too common notion that agriculture is essentially a
book study which can be taught independently of laboratory and
field.
6. Lack of definite form and content of the course.
This book is an attempt to obviate some of these difficulties by:
1. Planning a course that any wide awake, progressive teacher
who has had any scientific training can teach successfully.
2. Referring throughout to the best standard authors in order
to give the student a broader and clearer view than is possible
where only one book is used.
3. Securing the codperation of parents by bringing them into
direct contact with the work of the pupils in the home garden and
field.
4. Making the best possible use of illustrative material in the
laboratory, garden, and field, in order to give the students an oppor-
tunity to observe and study the fundamental . processes at first
hand.
5. Confining the work to a comparatively few essential topics
and providing a definite amount of laboratory work on each.
The bulletin consists of two parts. Part I is for the use of the
teacher and contains:
1. Suggestions concerning equipment.
2. General suggestions.
3. Outline course with lists of readings,
Part II is a pupils’ laboratory manual.

Il. GENERAL SUGGESTIONS TO TEACHERS.
1. The teacher should have a definite aim and plan for each
lesson, a clear notion of what he is going to do, the sources of informa-
tion and the material to be used.
2. As a general rule, the laboratory and field work should pre-
cede the study of the text. The following order is strongly recom-
mended :
a. The experiment, field or laboratory. Written or printed
directions for the work should be given. See Part II.
Pupils should be required to manipulate carefully, observe
closely, think connectedly, and record in writing.
b. The assigned readings.
ce. The recitation. Here the whole topic should be reviewed,
put in correct form and reduced to use. An opportunity
to show the bearing and use of the lesson on the home life
of the child and the community should never be lost.
4, Each student should keep a note book in which each labora-
tory and field exercise and each demonstration is carefully recorded
in good English. This note book should contain the date and sub-
ject of each exercise, a statement of the materials used, description
of the work done, and such illustrative drawings as may be necessary,
In preparing an index to his note book, the student should specify
whether the work is a laboratory exercise, a field exercise, or a demon-
stration made by the teacher or by another student. The index should
bear the teacher’s endorsement certifying that it is a true abstract
of the student’s work.
5. The course is planned for one year. At least two double
periods per week should be given to individual laboratory or field
work. It is expected that some schools will do more work than is
outlined and that each will place some emphasis upon such topics
12 A UNIT IN AGRICULTURE
as are of special interest to the community in which the school is
located.
6. While certain substitutions may be made in both library and
equipment, the lists given are considered minimum lists and should
be provided.
7. The course as planned presupposes no previous scientific
training on the part of the pupil, and may be placed in any year
of the high school. Students having had one or more sciences will
do more work than those who have had no such training. If physical
geography is taught, it is strongly recommended that this subject
be given in the first year and agriculture in the second year.
8. A beginning should be made. If the teacher cannot get
everything he needs, he should use what he has and can get. Much
good work can be done with only such equipment as teacher and
students can provide.
9. Remember that agriculture cannot be taught successfully
from a book alone. To attempt to do so when there is such an abun-
dance and variety of illustrative material is an unjustifiable waste of
time. The pupil should not study about soil; he should study soils.
10. The required readings are given in Part I rather than in
Part Ii for the reason that the teacher should carefully guide in the
work. The teacher knows best what reading is necessary and when
it is necessary. Each of the text-books gives some information con-
cerning most of the lessons. For this reason, the texts are not given
in the lists of readings. The teacher should select the best reference
from each text.
11. The teacher will find it necessary to exercise careful super-
vision over the library. If possible, a separate case for the agricul-
tural library should be provided. \
12. The lesson should be studied by the teacher in advance of
the assignment of class work. The required readings should be
selected and placed on the blackboard as necessary from time to time.
A UNIT IN AGRICULTURE 13
13. The teacher should not be satisfied with the literature given.
He will doubtless be able to find much additional that is as good or
better.
14. If possible a school garden in which each student has his
own plot of ground should be provided. For suggestions concerning
the equipment and management of the school garden, see Farmers’
Bulletins, Nos. 94 and 218, U. 8. Department of Agriculture, and
Agricultural Education, James A. Jewell, Bulletin No. 2 (1907),
Bureau of Education, Washington, D. C. The school garden may be
made the most interesting and profitable part of the work.
15. The books for special and general reference should be kept
by the teacher or librarian and should be taken from the library only
by permission: of the teacher. Many of these books will interest
patrons. With these books as a basis, an agricultural library should
be built up for the use of all the people in the community. The
high school should be made a social and agricultural center for the
community.
16. While the topics may be studied in other than the order
named, it is probable that the order given is best. In any event,
soil study should precede plant study, and farm management should
come last.
1%. It is believed that the average class can complete the course
as planned and do all the work well in one year of nine months.
18. If at any time suggestions are needed all the assistance pos-
sible may be secured by addressing your State Agricultural College.
19. Problems and review questions may be selected from the
excellent lists in Warren’s text.
20. This course is largely a compilation of what seems to be
the best features of several courses. It is at best only tentative and
will doubtless need revision. To this end, the author will appreciate
the criticisms and suggestions of teachers it.

FARM CROPS.
Ex. 1. A Grain of Corn.
Soak a few grains of corn in hot water for twenty minutes. With
a small sharp knife, remove the tip cap. This tip cap is a small cap
covering the end of the kernel. Beginning at the end where the hull
has been broken by the removal of the tip cap, pull off the hull in
strips. The part immediately under the hull and covering almost or
quite all of the kernel is called the horny gluten. Carefully remove
it by shaving it off with a sharp knife. Now carefully remove the
germ. Notice carefully the size, position and parts of the germ. After
the tip cap, hull, horny gluten, and germ have been removed, there
remains only starch, of which there are two kinds—the horny starch
and the white starch. The horny starch lies next to the horny gluten
on the back and sides of the kernel. The white starch occupies the
erown end of the kernel above the germ, and it also nearly surrounds
the germ toward the tip of the kernel. Separate, as far as possible,
the horny starch and the white starch. How many and what distinct
parts have we found? Make an enlarged drawing of grain of corn,
front view, showing and naming the parts.
Ex. 2. An Ear of Corn.
Material: three or four different varieties of corn grown in the
neighborhood. ‘Table the varieties by name. Observe carefully and
note the following: (1) color of grain, color of cob, and whether sur-
face of ear is smooth, rough or very rough; (2) number of rows, num-
ber of grains in a row; (3) total number of grains on the ear; (4)
whether the rows are straight or twisted, and, if twisted, which way;
(5) whether the grains are closely packed or loose, firmly attached to
the cob or loosely attached; (6) whether shape of ear is cylindrical,
conical, or irregular. Do you think the ear is well proportioned?
28 A UNIT IN AGRICULTURE
Note the butt of the ear and describe as even, slightly rounded. wel!
rounded, enlarged, etc. Describe and draw the tip of the ear. Notice
carefully the shape of the grains and their position on the cob.
Measure length of ear, circumference of ear. Find weight of corn and
weight of cob. Give percentage of grain. (The percentage should be
- from 86 to 90.)
Ex. 3. The Corn Plant.
Go to any corn field near the school.
Observe closely and note:
1. Name of variety.
2. Size of field.
3. Height of plant (average of ten plants).
4. Number of leaves on plant (average of ten plants).
5. Number of leaves below ear (average of ten plants).
6. Average leaf surface (take the product of the length and
breadth of the average leaf times the number of leaves).
%. Husks: whether abundant, medium or scarce.
8. Husks: whether close, medium or loose.
9. Height of ear above ground (average of ten plants).
0. Position of ear on the stalk: whether pendant, horizontal or
pointed upward.
11. Shank: whether long or short, strong or weak.
Measure ten hills square; give number of ears in one hundred
hills. Count the missing hills in the plot. Determine the percentage
of stand. Give number of stalks having two ears and number having
no ear. Find distance apart of hills each way. Give number of hills
per acre. Measure off one acre which represents a good average of
the field; husk one-twentieth of this, and, after weighing same care-
fully, estimate the average yield of field. If hills of corn are 3 feet 6
inches each way, how many hills to the acre?
If, in a field of corn planted 3 feet 6 inches each way, there is
on the average 114 lbs. of corn to each hill, allowing 10 Ibs. to the
bushel for shrinkage, what is the yield per acre?
. A UNIT IN AGRICULTURE 29
If corn is planted 3 feet 6 inches each way, and when mature is
cut and put in shocks, each shock containing torn from an area 14
hilis square, how many shocks to the acre? How many, if shocks are
16 hills square ?

Ex. 4. Corn Judging—Single Ear.
A good ear of corn may be described as follows:—The ear should
be from 9 to 1014 inches long and from 7 to 71% inches around, meas-
ured at a point 1-3 the distance from the butt to the tip. It should
30 A UNIT IN AGRICULTURE
be practically the same diameter from end to end; that is, it should
not be distinctly tapering. The rows of kernels should be straight
and the kernels should be of such a shape that they wiil fit tightly
together with no furrows left between the rows. The butts should be
well rounded out with kernels evenly arranged around a cup shaped
cavity about one inch across. The tips should be well filled out to the
end with deep, even kernels. The kernels of the ear should all be
very nearly the same size and shape. They should be wedge shaped,
but not pointed; they should have large, smooth hearts or germs, not
blistered or discolored. The length of the kernel should be about 114
times as great as its width at the widest part, and it should be of the
same thickness from one end to the other. The kernels should show
no mixture with corn of the opposite color. The cob should be of
medium size, neither very large nor very small.
Secure a number of ears of corn and notice the faults of each.
Pick out the ones that are most nearly perfect. Take an ear and
write a description of it, telling in what points it is good and in what
points it is imperfect.
Lay five ears of corn on the table and try to pick out the one hav-
ing the least number of faults. Go over the various points of the
ear as given in Lesson 4, in the description of a good ear, and place
that ear which is most nearly perfect on the left. Put the next best
one second, the third best third, and so on. In what ways is No. 1
better than No. 2? Give the good and bad points of each ear.
Ex. 5. Corn Judging—Use of Score Card.
At fairs and-other places where corn is shown for premiums, it is
customary to show ten ears together as a sample. Consequently, in
judging such samples, ten ears must be considered instead of a single
ear. To help in this judging, a card giving a scale of points arranged
to represent the different characters of the ears is used. This is called
a score card, and the one that is used in Missouri is as follows:

Following is an explanation of how to use the score card:
‘Maturity and soundness. (10.)
An ear that is not mature will not be perfectly tight. This is the
best determined by giving the ear a slight twist. The kernels
should all be sound and free from decay. For every ear not
perfectly mature and sound, deduct one point.
Uniformity of ears. (10.)
All ears in the sample should be as nearly alike in every way as
possible. This is very important. They should be the same
in size, in color and in character of kernel. For every ear
strikingly different from the average, deduct one point.
Shape of ears. (10.)
Ears should be practically the same diameter from one end to the
other. For each ear that is distinctly tapering, deduct one
point.
Length. (10.)
Ears should be between 9 and 1014 inches in length. For every
ear that is under 814 inches or for every ear that is over 1014
inches, deduct one point.
ae A UNIT IN AGRICULTURE
Circumference. (5.)
Ears should be from 7 to 71% inches around, measured at a point
1-3 the distance from butt to tip. For each ear less than 7
inches or over 734 inches, deduct one-half point.
Purity of cob. (5.)
Yellow corn should have red cobs, and white corn, white cobs
(with the exception of St. Charles White). A single ear with
a cob of the wrong color bars an exhibit from competing for
prizes.
Purity of kernel. (5.)
For every mixed kernel in the exhibit, deduct one-fourth point.
Uniformity of kernels. (5.)
All ears should have kernels of approximately the same size. For
every ear having kernels larger or smaller than the average,
deduct one-half point.
Shape of kernels. (5.)
Take out two kernels from the middle of each ear. Deduct one-
half point for each ear having poorly shaped kernels.
Character of germ. (10.)
Examine kernels of each ear as to character of germ and deduct
one point for each ear having poor germs.
Space between rows. (5.)
For each ear having wide furrows between the rows of kernels,
deduct one-half point.
Butis. (52)
For each poor butt, deduct one-half point.
Pipss 1(5.)
For each poor tip, deduct one-half point.
Size of Cob. (10.)
For each ear having a cob either too large or too small, deduct one
point.
A UNIT IN AGRICULTURE 33
Ex. 6. Testing Seed Corn for Germination.
Make a box 4 inches deep, 14 inches long, and 12 inches wide,
Fill the box half full of moist earth, packing it down firmly so that
the surface is even and smooth. Rule a piece of white cloth, the size
of the box, into squares 2 inches each way. Number the squares 1, 2,
3, 4....30. Place the cloth on the soil in the box and tack it to the
corners and edges of the box to keep it in place. Number thirty ears
of corn. Take ten grains from each ear—from middle, tip, and butt.
Place these grains on the square corresponding to the number of the
ear. When all the samples are im place, cover with a piece of cheese
cloth the size of the box. Now cover with a heavier cloth larger than
the box and over this place about 2 inches of moist earth. Put in a
warm place and let it remain ten days.
Carefully remove the cover. Now make a careful study of the
ten kernels in each square and carefully note those which either failed
to grow or are weak in vitality. In how many and in which squares
did all the kernels germinate? In how many and in which squares
did no kernels germinate? If you had planted all the seed from these
thirty ears, what per cent of a stand of corn would you have?
Ex. 7. Study of a Grain of Wheat.
Soak a few grains of wheat in warm water. Using a lens and a
small sharp knife, try to remove the coverings of the grain. There
are four of these, three epidermic layers and one testa or true seed
coat. These coats constitute the bran and make up about 11 per cent
of the grain.
Immediately under the testa, find the endosperm. This makes
up the large part of the seed and is the flour of commerce. Notice
the position, form and size of the embryo.
Ask your teacher to cut a thin slice across the grain, place in a
drop of water on a glass slide, cover with a cover glass and place
under the low power of the compound microscope.
Observe carefully and draw, naming the parts.
34 A UNIT IN AGRICULTURE
Ex. 8. Study of a Head of Wheat.
Observe that the grains are arranged in groups on either side of
the stem. A single group is called a mesh. How many meshes on
this head? How are they arranged? How many grains in a mesh?
Is the number uniform? Are the meshes all filled? Find a mesh
with three grains, with four, with five. Carefully remove the cover-
ing from a single grain. How many coverings are there? How is
the grain attached ?
Ex. 9. The Wheat Plant.
Pull up an entire wheat plant. How many stalks in the bunch?
Does the number vary with different bunches? How many joints in
each stalk? How many leaves on each stalk? Observe the form and
arrangement of the roots. From the data in Ex. 8 and 9, estimate
the number of grains that is produced by one grain.
Ex. 10. Study of a Head of Oats.
How does the oat head differ from the head of wheat? In what
ave they alike? Make drawing. Carefully remove a single grain.
Notice the hard outer cover. Remove the hard cover and make an
enlarged drawing of the kernel, naming parts.
Ex. 11. Study of the Legumes. =
Material: red clover, alsike, white clover, alfalfa, soy beans, cow
peas. The specimens should be fresh, but dried ones may be used.
Study each plant separately.
1. Observe the number, arrangement, size and shape of leaves,
and make drawing of a leaf.
2. Observe the number and height of the stems, and the diameter
of stem an inch above the ground. Are the stems erect, spreading,
decumbent, or training?
3. Are there many, few or no branches?
4. If in bloom, notice the place, form, color, and size of blossoms.
Make drawing of a blossom.
5. If in seed, note kind, number, and shape of seed pods. Note
A UNIT IN AGRICULTURE 30
number of seed-in pod and size and form of single seed. Draw seed
pod, using magnifier. Make enlarged drawing of a single seed.
6. Observe carefully the form, size, number and length of the
roots. Look closely for small nodules on the roots. These nodules
are very important and we shall learn more about them later. Make
drawing of root.
Ex. 12. Study of the Irish Potato.
Material: potatoes, preferably of several varieties, with some
showing scab, dry rot, etc.
Note the following:
1. Variety: whether early, medium, or late.
2. Shape: whether cylindrical, oval, flat oval, compound, regu-
lar or irregular.
3. Size: whether large, medium, small, uniform or not uniform.
4. Shape of eyes: whether deep, medium or shallow; oval or nar-
row and elongated; large or small (small as compared with size of
tuber) ; numerous or few; uniformly distributed or mainly at bud
end; ridge prominent or ridge not prominent.
5. Color: whether yellowish white, pink or russet.
6. Texture of skin: whether corky, netted or lenticoled; glossy
smooth or dull smooth.
?. Color of skin: whether yellowish white, russet, red, pink or
blue; uniform or not uniform.
8. General characteristics: whether clean or dirty; cracked or
not cracked ; if diseased, whether scab, dry rot or blight.
9. Color of flesh: whether white, yellowish, pink or blue.
Make a drawing of the tuber, showing eyes, and indicate which
is the stem end of the tuber.
SOILS.
Ex. 13. Study of Soil.
Material: a handful of soil ee the school yard. What is the
color of this soil? Are all the particles the same color? Wet a little
36 A UNIT IN_AGRICULTURE
and observe whether there is a change in color. Feel the soil. Is it
smooth, sticky, or gritty? Do you find small pieces of rock in it?
Examine closely with the hand glass and describe fully all that you
see. Try to find out what the hard particles are. If they will scratch
glass, we may be quite sure that they are some form of quartz. Put
some of the soil in a large test tube, cover with water, shake thorough-
ly and set aside for a few minutes. Which part of the soil goes to the
bottom of the tube? Which next? Make a drawing of the soil in the
tube. By digging a few holes in the home garden or field, try to find
out whether the arrangement of the soil particles is the same as
in the tube. Examine the soil along a stream to see whether you
can find illustrations of sorting soil by water. Pour off the water
from the soil in the tube, and evaporate to dryness. Is there any-
thing left? What do you suppose it is? What does this prove?
Examine the inside of a tea kettle for a scale of covering. How did
it get there? Its presence there proves what?
Ex. 14. Study of Soil (continued).
Material: a handful of soil from the school yard. Carefully weigh
a small handful of the soil. Now dry thoroughly, being careful not
to burn any part of it, and weigh it again. Account for any difference
in weight. The loss in weight is what per cent of the weight before
drying? Now place the dry soil in a sand crucible or iron pan and
heat hot. Cool, weigh, and examine carefully. Account for any
loss in weight. Do you believe that you could burn all of the soil?
Do you notice any difference in color after burning? Do you know
what it was that burned ?
Ex. 15. Study of Soil (continued).
Repeat Exercise 14, using the richest black soil you can get from
the home garden. Compare the results with those obtained in Exer-
cise 14. Compare results with those obtained by one of your class-
mates who used the same soil. Is there substantial agreement? Try
to account for any difference.

Ex. 16. Field Lesson.
Material: a suitable field as near the schoolhouse as possible. Do
you find any ledges of outcropping rock? I you do, break off a small
piece and compare the freshly broken surface with the outside or
weathered surface. Note carefully any difference. Do you find any
boulders or pebbles? Break one open and compare the freshly broken
surface with the outside surface as before. Are the boulders and
pebbles of the same material as the rock in the ledge? Select a piece
of each different rock you find to take to school for future study.
Look along the bed of a stream for pebbles. (If there is no stream
at hand, this work may be done at another time and place by indt-
vidual pupils.) How do the pebbles in the bed of the stream com-
pare in size and shape with those back from the stream? How do
you account for the difference ?
Find some good rich soil and dig a hole about 18x12 inches and
18 inches to 2 feet deep. Observe closely the material and the color
at different depths. Notice especially the amount of black soil.
Make a drawing of one side of the wall. Repeat this exercise by
digging the hole on a steep slope. Account for any differences in
the soil at the two places. What is subsoil? Which do you think
will grow the better crop, the side hill or the lowland? Why? From
your observation of farm crops, can you state whether this is gen-
erally true?
Ex. 17. Soil Texture.
Material: sand, clay, and loam—two small fruit jars full of each,
from the farms in the neighborhood of the school, if possible. Label
each jar and set one jar of each aside for use in Exercise 18. Com-
pare the three kinds of soil as to color, texture, and amount of humus.
Put some of each kind in a large test tube, cover with water, shake
thoroughly and set aside. Which settles most rapidly? Most slowly?
Which contains particles that float? If these soils were poured into a
running stream which would be carried farthest? Put a little hydro-
chloric acid on each and note the result. Mix the three samples in a
38 A UNIT IN AGRICULTURE .
large test tube or long bottle, cover with water, shake thoroughly and
set aside. Which soil is at the bottom? Which at the top? Make
drawing of tube. Compare with results of Exercise 13. Dry some
of each kind of soil as in Exercise 14. Weigh very carefully about
the same amount of each, and put in separate beakers. (Hach soil
should be pulverized after drying.) Pour water into each beaker
from a graduate containing a measured quantity, until the water
rises to the surface of the soil. Find how much water it takes in each
case, recording results as follows:
Sand Clay Loam
Volume of soil
Volume of water added
Per cent of air space
The amount of water is the approximate measure of the air space.
Which soil contains the most air? Which least?
Ex. 18. Temperature of Soils.
Material: the three jars of soil set aside in Exercise 17. Into
each jar pour sufficient water to wet thoroughly. In each jar put a
thermometer so placed that the bulb is just below the surface of the
soil. Weigh each jar and set the jars close together in the window
and where the sunlight can strike fairly. Take the temperature and
weight of each jar at the same hour of the day on alternate days
for one week. Record the results as follows:
Sand Clay Loam
Weight first observation
Weight second observation
Weight third observation
Temperature first observation
Temperature second observation
Temperature third observation
Which soil shows the highest temperature? Which the lowest?
From which does the water evaporate most rapidly? From which
does it evaporate most slowly? What is meant by a warm soil? By a
A UNIT IN AGRICULTURE 39
cold soil? By a dry soil? By a wet soil? Review Exercise 14 and
state whether there is any relation between soil temperature and air
space. What are some of the ways in which a cold soil may be made
warmer ?
Ex. 19. Water Capacity of Soils.
Material: different kinds of soils, five long-necked bottles with
the bottoms broken off, rack for holding bottles, five tumblers. Tie a
small piece of cheese cloth over the mouth of each bottle, place in the
frame upside down with a tumbler under each. Fill the bottles to
the same height, about two-thirds full, with different kinds of soil.
Firm the soils by shaking the bottle. With watch in hand and glass
of water held as near as possible to the soil, pour water into one of
the bottles just fast enough to keep the surface of the soil covered.
Note how long before the water begins dropping into the tumbler
below. Do the same with each of the other bottles. Which takes in
water most rapidly? Which most slowly? Which is the most porous?
Which is the least porous? Compare results with results in Exercise
18. What happens to the less porous soils when a heavy shower of
rain comes? Repeat the experiment with any two of the soils, pack-
ing the soil in the bottle tightly before pouring in the water. What
is the «fect of packing? Does this experiment have any bearing on
farm practice? What bearing has it? Which of the soils could absorb
the heaviest shower? Which soil continued to drip longest? Which
would drain most readily ?
Ex. 20. Capillarity of Soils.
Material: same as in Exercise 19. Fill each bottle with a differ-
ent kind of dry soil. Fill each tumbler about two-thirds full of water
and set the bottles, neck down, in the tumblers so that the cheese
cloth is just above the bottom of the tumbler. Observe the rise of
water in the different soils. Note how high it rises in each bottle and
the time it takes. In which soil does the water rise most rapidly?
In which to the greatest height? Which soil draws up the greatest
amount of water? This can be determined by measuring or weighing
40 A UNIT IN AGRICULTURE
the water in the tumbler before and after the experiment. This power
of soils to raise water from below is called capillarity, and the water
is called capillary water. Because of this capillarity, plants are able
to get moisture from the subsoil in time of drought. What effect on
water capacity does the addition of organic matter have? Give one
method by which the farmer may increase the amount of organic mat-
ter in the soil. ;
Water that percolates through the soil until it reaches the rock
or hard pan is called soil water. How deep are the wells in your
neighborhood? Are they deeper on the upland than on the lowland ?
Is the impervious layer rock or clay? Are there any springs? If so,
observe the character of the strata over which the water flows.
Ex. 21. Absorption of Moisture from the Soil.
Material: a wide mouthed bottle, an egg, a glass tube 3 or 4
inches long and about 14 inch in diameter, a candle and a piece of
wire about 5 inches long.
Remove part of the shell, about the size of a dime, from the large
end of the egg, without breaking the skin beneath. In the same man-
her remove a piece of shell, no larger than the diameter of the glass
tube, from the small end of the egg. Cut from the lower end of the
candle a piece about 14 inch long and bore a hole in this the size of
the glass tube. Soften one end of the piece of candle and stick it on
the small end of the egg so that the hole in the candle covers the hole
in the egg, making a water-tight joint. Place the glass tube in the
hole in the candle, cement closely as before. Now run the wire down
the tube and break the skin of the ege. Now fill the bottle with
water until it overflows and set the egg over the mouth of the bottle,
small end up. In an hour or so, the white of the egg will be seen ris-
ing in the glass tube. The water enters the egg through the skin and
forces the white to rise in the tube. The skin itself has no openings
that can be seen even with a microscope. This process by which a
liquid passes through a membrane is called osmosis. It is by this
A UNIT IN AGRICULTURE 41
process that water containing plant food enters the fine root hairs of
plants.
Ex. 22. Absorption of Moisture from Soil (continued).
Material: thistle tube, piece of waste bladder, jar, water and
molasses. Partly fill the thistle tube with molasses. Tie the bladder
over the large end of the tube and insert into the jar of water. Put
the tube into the jar so that the molasses in the stem is just on the
level with the water in the jar. Fasten the tube in this position and
observe what happens. Explain.
Ex. 23. Rise of Water in Plants.
Fill a tumbler one-third full of luke warm water colored with a
few drops of red ink or some brilliant coloring matter. Place in the
colored water the freshly cut stem of a white carnation, lily or almost
any soft green plant. Observe closely and explain what happens.
Ex. 24. Rise of Water in Plants (continued).
Pull up any good sized green plant, as, for instance, a bunch of
clover. Weigh it carefully and record the weight. Now dry the plant
thoroughly, being careful not to burn it, and weigh again. What are
the percentages of dry material and water as shown by the weights?
Estimate the number of pounds of water in one ton of freshly cut
clover hay.
Note.—It has been found that corn roots take up over 300 lbs.
of water for each pound of dry matter produced. Oats and clover
take up 500 lbs. What two important facts are shown by this experi-
ment?
Ex. 25. Effects of Excluding Air from the Soil.
Into a fruit jar or water-tight can containing a healthy growing
plant, pour water until the surface of the soil is covered to the depth
of one inch. Keep the soil covered with water, observe the plant
closely for several days and note results. Have you noticed the effects
of standing water on young corn? If not, do so. Would you say the
plant has been smothered or has it been drowned? Why? Can you
suggest a method of soil ventilation ?
42 A UNIT IN AGRICULTULE
Ex. 26. Soil Temperature.
Review Exercise 19. Which of the soils was warmest? What
coldest? In the same jar of soil insert two thermometers, one to the
depth of 2 inches and one 6 inches. Do you notice any difference in
the temperature shown? Try this experiment out of doors and note
the temperature of the. air as shown by the third thermometer sus-
pended a foot above the ground. Make three observations the same
day, one at 8:00 a. m., one at 2:00 p. m. and one at 6:00 p.m. Is
the surface of the soil warmer or colder than the air? Is this true
of all times of the day? If not, when? Is the average temperature
of the surface soil higher or lower than the average temperature of
the air? Which is more nearly uniform, the temperature of the air,
the surface soil or the soil at a depth of 6 inches? Do you know
whether each of your conclusions above will hold for different seasons
of the year? Should seeds be planted deeper or shallower in early
spring or late spring? Why?
Ex. 27. Soil Drainage.
Take two flower pots the same size and label them 1 and 2 re-
spectively. In No. 1 pour melted paraffin or wax to plug up the hole-
so that no air can get through. In the bottom of No. 2 put about one
inch of fine pebbles or coarse sand. Nearly fill each pot with a
mixture of good soil and sand, three parts soil and one part sand.
Place in each pot a healthy growing plant of the same kind and size.
Sprinkle each with water till the soil is saturated and place the pots
in a sunny window. In each pot place a thermometer with a bulb at
a depth of two inches. Every two days note the temperature of the
soil and the condition of the plants in each pot. If each of these con-
ditions of soil and moisture were found in a field, which would be
more apt to be flooded in time of rain? In which could the air pene-
trate more readily? In which would the temperature be higher?
Every two or three days apply equal quantities of water to each pot.
At the end of a month remove the plant, soil and all. In which pot
have the roots gone deeper? In which would they go deeper, the
drained or undrained soil?
A UNIT IN AGRICULTURE 43
PLANT PROPAGATION.
Ex. 28. Absorption of Water by Seeds. S
Soak a few beans in luke warm water. Notice closely the appear-
ance of the bean at the end of ten minutes and at the end of forty
minutes. What changes in form of surface and size of bean? With
a hand lens, examine the bean closely to find the place where the water
gets in. Try the same experiment, using three or more of the fol-
lowing seeds: squash, apple, gourd, pea, corn, pumpkin.
Ex. 29. Effects of Temperature Upon Seed Germination.
Prepare two pieces of canton flannel a little larger than a dinner
plate. Wet one piece and place it on the bottom of the plate. On this
place a few seeds—squash, corn, or butter beans. Moisten the second
pieee of cloth, lay it over the seeds and cover with a pane of window
glass. Prepare a second germinating apparatus in precisely the same
way. Place one of the plates in a warm place, 80 to 120 degrees if
possible; place the other in a cold place at or near the freezing point
if possible. (The refrigerator may be used in summer.) At inter:
vals of two days examine each and note results.
Ex. 30. Effects of Air Upon Seed Germination in Water.
Fill two small wide mouthed bottles with water. Shake one thor-
oughly and put a few seeds of different kinds in it. Remove the water
from the other bottle and boil it. Pour it back into the bottle and
put in it the same number and kind of seeds. Cover the surface of
the water in the last bottle with oil, set both in the window and note
results. In which bottle do the seeds germinate best? Why? Exer-
cises 6, 28, 29 and 30 indicate quite clearly the conditions of seed
germination. What are these conditions? Give an illustration from
your own experience on the home farm or garden to show that all
these conditions must always be present when seeds germinate well.
Ex. 31. Purity of Seeds.
Material: clover seed from several sources, alfalfa, timothy, wheat
and millet. ‘The price of each sample should be ascertained. Weigh
out three grams of seed and spread on a sheet of paper. Using a
44 A UNIT IN AGRICULTURE
\
lens, separate the seeds into three piles: (1) chaff, dirt, broken seed,
etc.; (2) weed seed; (3) clover seed. Weigh each lot, record the
results and save the clean seed. Considering price, quality and weeds,
which sample should be purchased.
Ex. 32. Propagating Bed.
Prepare a box five or six inches deep, three feet wide and any con-
venient length (to be determined by the size of the window). Place
the box on a firm support and fill with clean sand thoroughly wet. If
the class is large and the windows small, two or more such beds will
be needed.
Ex. 33. Cuttings.
Make cuttings from any or all of the following plants: geranium,
eoleus, wandering Jew, rose, heliotrope, chrysanthemum, begonia,
California privet. Make a small hole with a stick or pencil, insert
the cutting and then pack the sand firmly with the fingers. If the
bed is properly made and placed, most of the cuttings should grow.
When the cuttings are well rooted, they may be transplanted in pots
or in the garden.
Ex. 34. Grafting. (Demonstration by Teacher.)
The teacher will prepare the roots, scions, knife and wax, and will
do the work before the class, explaining each step. Each student make
drawings of each kind of graft.
Ex. 35. Grafting.*
Each student provide material and make not less than six grafts.
Ex. 36. Budding. (Demonstration. )
The teacher will do the work, making all necessary explanations.
Ex. 37. Budding.*
Each student bud a definite number of plants in the school garden
or home orchard.
* Tf possible, students should do considerable grafting and budding at
home, or elsewhere, while the method is clear in their minds.

Ex. 38. Effects of Air Upon Seed Germination in Soil.
Into each of two fruit jars containing rich sandy loam, put a few
seeds of wheat, corn and beans. Moisten the soil in both jars, screw
the top on one tight, being sure to keep the rubber band in place.
Leave the other open. Set both in a warm lighted place and note re-
sults at the end of one week, two weeks, three weeks. What does this
experiment teach?
Ex. 39. Relation of Light to Growth.
Prepare two fruit jars as in Exercise 38. Put one jar in a closet
or dark basement to exclude the light, and note results. Substitute
for the fruit jars and seeds flower pots containing growing plants.
Are plants attracted by the light? Plan an experiment to prove. Why
do trees grow taller when planted near together than when planted
far apart?
Ex. 40. Relation of Temperature to Growth.
Note.——The work will vary with the facilities for maintaining
fixed temperatures. Try to germinate seeds and grow plants at dif-
ferent temperatures. Work out fairly accurate answers to such ques-
tions as the following: What is the lowest temperature at which corn
will germinate? At what temperature does it germinate most quick-
ly? ete.

46 A UNIT IN AGRICULTURE
Fill seven four-inch flower pots with clean sand. Number the pots
and place plant food in each as follows:
No. 1. Nothing.
No. 2. Ten grams lime.
No. 3. Ten grams lime and one gram potassium chloride.
No. 4. Ten grams lime and one gram acid phosphate.
No. 5. Ten grams lime and one gram sodium nitrate.
No. 6. Ten grams lime and one gram each of the compounds
used in Nos. 3, 4, 5.
No. 7. About one-half pint of manure.
Mix the materials in each pot, then plant five kernels of wheat in
each. Record the growth of the plants from day to day, noting dif-
ferences in color and amount of growth. Let the plants grow until
the differences are clearly apparent.
Ex. 46. Air-Derived and Soil-Derived Elements.
Select a dry plant or a piece of dry wood. Weigh it carefully.
Now burn it and weigh the ashes: What per cent of the plant burned ?
This method gives a fair approximation of the amount of materials
derived from the air and amount of materials derived from the soil.
Review the following questions :
Will any seed germinate in a perfectly dry soil? Will any plant
grow without some moisture? Why is there so little vegetation in the
desert? What is a desert? What is meant by a drouth? What
would be the effects on this country of a total cessation of rainfall ?
Ex. 47. Bacteria and Molds.
Material: three test tubes, cotton, boiled potato, fruit or apple
sauce, three apples, one partly decayed.
Fill each tube about one-third full of apple sauce. Plug each
with cotton. Set one aside. Put the other two into a pail of water
and boil for half an hour. After boiling, set one tube aside with the
cotton undisturbed. Take the cotton from the third tube, leave it
out half an hour or more, and then put it in again. Leave these for
a few days, note what happens and account for different results. Is
A UNIT IN AGRICULTURE 4?
it desirable to leave canned fruit open a few minutes before covering
after cooking? Why?
Prick one of the sound apples in several places with a pin. Put
the pin into the rotten apple and then into the other sound apple.
Repeat this in several places. Set the two sound apples aside for
about a week. Note what happens and account for the different
results.
What is pasteurization, and how may it be performed at home?
Why discard the first few streams of “foremilk?” Why not feed just
before milking? Explain sour bread and formation of vinegar from
cider. What principle is employed in preserving silage?
Ex. 48. Preparation of Bordeaux Mixture.
Material: copper sulphate, lime, potassium ferrocyanid, balances,
two Mason fruit jars (quart size).
Bordeaux mixture is prepared by using 2 to 6 pounds of copper
sulphate to 50 gallons of water and adding enough lime to neutralize
it. Four pounds to 50 gallons of water is a good formula for use on
many plants.
(a) Put five cents’ worth of potassium ferrocyanid into a 4-ounce
bottle of water and label it “poison.” (b) Dissolve 2 ounces of cop-
per sulphate in a pint of water. (c) Slake about 4 ounces of lime.
Put 3 fluid ounces of (b) into each of the two jars. Fill the second
jar nearly full of water. Add some of (c) to each jar and test with
(a). If there is enough lime to neutralize the copper sulphate, (a)
will retain its yellow color when a drop of it is added. If there is
not enough lime, it will assume a decided brown red color. Add (ce)
until the test is satisfied. Then add as much more. Now fill each
jar with water. In which case does the mixture settle more quickly
and what is its color? These proportions give a mixture at the rate
of 4 pounds of copper sulphate to 50 gallons of water. It is usually
best to use double the lime called for by the test, because there is then
less danger of injuring the plants sprayed. Note that the mixture
containing the copper sulphate solution diluted before adding lime
48 A UNIT IN AGRICULTURE
did not settle as quickly as the other. The copper sulphate should
always be diluted with nearly all the water before the lime is added.
Some bulletins state that both should be diluted and then »ut to-
gether, but this way is quite as good and is easier.
Ex. 49. Insect Net.
Material: a handle about three feet long (an old broom stick
will do), a piece of No. 3 galvanized wire three feet six inches long,
and three-fourths of a yard of cheese cloth.
Bend the wire into a ring about a foot in diameter and bend back
about three inches of each end to insert into a hole made in the end
of the handle. Fasten securely. Make the cheese cloth into a bag
with rounded bottom and just wide enough to fit the wire loop; fasten
securely.
Ex. 50. Killing Bottle.
Take any small, wide-mouthed bottle—a quinine bottle or pickle
bottle will do. Secure a cork that will fit the bottle closely, and that
is long enough to handle easily. Get two cents’ worth of cyanide of
potassium, and one cent’s worth of plaster of Paris. Put the cyanide
in the bottle, cover with water and add the plaster of Paris until
all the water is soaked up. Leave the bottle open in a shady place
for an hour, when the plaster should be hard. Cork the bottle and
label it poison. Now it is ready for use.
Caution.—Do not breathe the fumes of the bottle.
Ex. 51. Insect Box.
Secure an empty cigar box. Cover the bottom with some soft ma-
terial as cork, cork linoleum or pith of dried corn stalks. Fasten
this material to the bottom of the box with glue and cover with
white paper.
If your collection is to be a permanent one, make a glass cover
for the box and fit it air tight.
Ex. 52. Spreading Board.
The spreading board may be any length. Material: two strips of
soft wood, 1144 inches wide and 1% inch thick; one piece 314 inches
A UNIT IN AGRICULTURE 49
wide, 1% inch thick; two cleats 314 inches wide by 34 inch by 1%4
inch; one strip of cork linoleum a little less than 1 inch wide and
as long as the longest strips. : ;
Place the two narrow cleats % inch apart and fasten on the
under side to the longer cleats. On the same side as the cleats, tack
the cork or linoleum over the open space. Now tack the whole to the
bottom board, which should fit exactly.
Ex. 53. Killing and Mounting Insects.
Immediately after having caught the insect, put it in the killing
bottle and cork tightly.
For mounting all insects except the butterfly and moth use the
insect box. Stick a steel pin (a sewing needle is better) through the
insect so that the insect is about 14 an inch from the point. Now
stick the needle about 14 inch into the cork at the bottom of the box.
Write the name of the insect on a piece of white paper and fasten
near the pin.
To use the spreading board, do as follows:
Kall the moth or butterfly as before, and mount within half an
hour. Insert the pin, with the insect on it, into the cork just far
enough so the body of the insect will be in the space between the
boards up to the wings. Place the wings out flat on the board and
fasten them with narrow strips of paper held by pins. Arrange the
wings so that the rear margins of the front wings will just cover the
front margins of the rear wings and shall be at right angles to the
body. Now pin larger pieces of paper so as to hold all firmly until
dry.
Ex. 54. Study of Cuts of Beef.
Study Farmers’ Bulletin No. 41. Copy drawing of ox showing
different cuts of beef.
Ex. 55. Study of the Egg.
Each student should be provided with two hen’s eggs. With the
ends of the egg in the hollow of the hands, press firmly. Account
50 A UNIT IN AGRICULTURE
for the great strength of the shell. Break a fresh uncooked egg in a
saucer or plate by separating the shell in the middle. Observe:
1. The germinal disc (a light colored spot usually found on the
upper surface of the yolk). What is the function of this
part ?
2. The transparent albumen or white of the egg.
Examine the shell and find the air space. Where is the air space?
Of what use is it? Observe the two membranes best seen at the air
space where they separate.
Examine a piece of the shell with the microscope, and observe the
pores. What would be the effect on the chick while in the egg if the
shell were covered with varnish ?
Note the color of the egg. Ascertain whether the eggs from any
particular hen are all of the same color.
Boil the egg and carefully cut lengthwise through the middle. Ob-
serve all closely and make drawing of either half, showing and naming
all parts. Make an exact drawing, omitting nothing. Use colored
crayon, if convenient.

FARM MANAGEMENT.
Ex. 63. Plan of Farm.
Take the measurements of the home farm. Make plot of farm;
scale, one inch==660 feet. Show location of cultivated fields,
pastures, timber, barn lot, orchard and garden. Show location of all
buildings and all wells, ponds, or springs.
Ex. 64. Plan of Home. ;
Measure and make to scale a floor plan and cross section of your
home. If you can, make a good drawing of the home.
Ex. 65. Plan of Barn. :
Having read the references assigned by the teacher and knowing
the kind and number of animals to be provided for, make ground plan
of barn; scale, one inch = 6 feet.
Ex. 66. Examination of Fertilizers.
Study small samples of all fertilizers available. Test each with
litmus paper. Learn name, composition and price of each. Observe
color, odor and form.
Ex. 67. Experimental Test of Fertilizers.
This experiment takes time and can not be completed before Sep-
tember. If there is no school garden, ask some farmer in the neigh-
borhood to rent you the necessary land. Lay off one-half acre of land
in plots, each plot being precisely one-tenth of the whole, or one-
twentieth of an acre. Mark the division points by'stakes set well in
the ground and number the plots from one to ten.
On plot No. 1, sow nothing.
On plot No. 2, 8 lbs. of nitrate of soda and 16 lbs. of acid phos-
phate.
On plot No. 3, 8 lbs. of nitrate of soda and 4 Ibs. of muriate of
potash.
On plot No. 4, 8 lbs. of nitrate of-soda, 16 lbs. of acid phosphate
and 4 lbs. of muriate of potash.
On plot No. 5, 20 lbs. of any commercial fertilizer used in the
neighborhood.
On plot No. 6, nothing.
On plot No. 7, 500 Ibs. of barnyard manure.
A UNIT IN AGRICULTURE 63
On plot No. 8, 8 lbs. of nitrate of soda.
On plot No. 9, 16 lbs. of acid phosphate.
On plot No. 10, 4 lbs. of muriate of potash.
Do this work in early spring. Plant the entire plot in corn or
potatoes and cultivate carefully. In the fall, gather and weigh the
crop. Which plot made the best yield? Which made the poorest?
Arrange the plots according to the yield. Considering the market
price of the corn or potatoes, did it pay to fertilize? Which plot
shows the highest per cent of profit?
Ex. 68. The Home Garden.
Make drawing of plan for a vegetable garden to supply the home
with a succession of vegetables. Indicate the area planted to differ-
ent vegetables, the approximate time of planting, distance between
rows, method of planting and cultivating.
Note.—It is important that the garden be arranged for cultiva-
tion by horse power.
Ex. 69. Farm Forestry.
Visit the woods on a farm. Find out what trees the method of
cutting has favored, and what are the leading kinds, with the pro-
portion of each. Learn the names of the common trees. Note that
much of the cutting in woods is done in such a way as to leave the
undesirable trees—the tree weeds.
Ex. 70. Agricultural Manufacturing.
Visit a creamery, vinegar factory, evaporator, canning factory or
other similar industry. Note the different operations and refer to the
scientific principles involved.
Ex. 71. The Babcock Test for Butter-Fat in Milk.
This exercise should first be performed by the teacher as a demon-
stration exercise and then by the individual students.
Caution—Examine the apparatus and read the directions care-
fully before using it. When pouring the acid into the milk, be sure
that the bottle is not pointed toward yourself or any other person.
Mix the milk by pouring it back and forth between two vessels
several times. Place the small end of the pipette near the center of
64 A UNIT IN AGRICULTURE
the milk and suck up the milk above the 17.6 ¢.c. mark. Quickly put
the index finger over the upper end of the pipette; and, by releasing
the pressure, allow the milk to run out until its upper surface is even
with 17.6 ¢.c. mark when the pipette is held straight up and down.
Place the point of the pipette a short distance into the test-bottle
neck, holding it against the glass and with both pipette and bottle at
an angle. Remove the finger to allow the milk to flow into the bottle.
Be sure to get every drop of the milk, taking care to drain the pipette
and to blow the last drop into the bottle.
After all the samples of milk to be tested have been measured,
the acid should be added. Fill the acid measure to the 17.5 ¢.c. mark
with acid that is neither very cold nor very hot. Pour this into the
bottle with the milk, holding the bottle in a slanting position. The
acid will then carry down any milk left in the neck, follow the glass
surface to the bottom of the bottle and form a layer under the milk.
Hold the bottle by the neck and give it a circular motion for a
few minutes, mixing the milk and acid until no milk or clear acid is
visible. By this time the contents will be dark colored and hot. This
change is due to the acid dissolving all the solid constituents of the
milk except the fat, which it does not affect. |
Place the bottles in the machine so that each one will have an-
other directly opposite, to keep the machine in balance. Whirl the
bottles five minutes at the proper speed for the machine in use. Then
stop it; and, with the pipette or other convenient means, add hot
water to each bottle until the contents come up to the bottom of the
neck. Whirl two minutes. Add hot water enough to bring the top of
the fat nearly to the top of the graduations on the neck of the bottles.
Whirl one minute. The fat should then form a clear column in the
neck of the bottle.
Reading the Percentage. Keep the fat warm so. that it will be
in the fluid condition. Hold the bottle by the upper end of the neck,
