THE TREE AND MAN. 
These engravings are iiilrorluced here to teach you an important lesson. You must understand that 
the machinery for building our own bodies is almost identical to that which builds up the plant While it is 
true that the different parts of this complex machinery are dependent on others, yet one part may become 
weak and another part strong by different treatment. We shall see in the following pages how the seed and 
truit producing organs can be developed and kept in a condition to use the vegetative part of the plant as a 
supporting machinery for manufacturing Big Red Berries instead ol the mass'of small berries and profusion 
ot runners and foliage found on the plants of the average grower. You will see how we can guide the 
growth of the plant, making it take any form we may desire. This is what thorough breeding me.-nis. 
may be .strengtliciied by substantially the same 
means. 
Let us see Iiow the man grows or how his 
body is built up. Observe how he takes his 
food at the mouth, passing it to the stomr":li, 
thence to the intestines, liver and lungs where' 
it is converted into blood, a substance which 
contains all the materials for building up the 
body. The heart now forces this pure blond 
through the arteries to all the tissues of llie 
body. Our bodies are 'itcrally filled with 
workmen which are called glands, taking the 
materials out of the blood and building up the 
bone, flesh and sinews just like a lot of carpen- 
ters, stone masons, brick layers, i)lumbcrs and 
plasterers building a house. These workmen 
in our bodies are divided in the same general 
way. Some build the bone, others the flesh, 
and still others the sinews. The especial point 
to note is that each class does its special work 
just as the house builders do and cannot swap 
jobs. 
The i)lant cats manure and the animal eats the 
plant and when the animal dies, its flesh is 
put back into the ground to be eaten in turn by 
the plant. So-called commercial fertilizers are 
largely made of the blood, bones and flesh of 
animals. 
TREE AND MAN. 
Some people object to using plants and ani- 
mals in comparison and this objection arises 
out of a lack of knowledge concerning the 
close resemblance of their anatomical parts. 
The only reason I do ,so is that most people 
are familiar with the anatomy of animals and 
it is easier to explain by comparison. To 
make this inore clear, I secured the services of 
an anatomical artist who prepared a chart ex- 
pressly for this book showing the digestive and 
assimilating organs of both a man and a 
tree and will point out how any part of either
