Extent of the Undertaking. 
Work of this nature should never be undertaken on too large 
a scale. If too many seedlings are planted, the care of the nur- 
sery may prove so much of a burden that the students will find 
no pleasure in it, and when the trees are grown it will be hard to 
dispose of them without loss. Should the trees die, the natural 
inference on the part of the pupils would be that the work done 
by them in caring for the young trees was useless. It should 
therefore be the endeavor of each school to raise but a few trees 
per pupil, but to grow these successfully and to transplant all of 
them with the smallest possible loss to permanent sites on the 
school grounds or about the homes in the community for shelter, 
timber, or ornamental purposes. This aim must be impressed 
upon the pupils if the lesson of the value of forest trees is to be 
taught. If only one tree per pupil is grown, but every one safely 
transplanted to a permanent site where it may grow into useful- 
ness and beauty, the work of the nursery will be infinitely more 
satisfactory than if hundreds of seedlings are produced and many 
of them allowed to perish. 
Cooperation Bctzveen Schools. 
It will add greatly to the pupils' interest in the tree nurseries 
if schools located in different parts of the country exchange sup- 
plies of tree seeds. It is suggested, therefore, that each school 
endeavor to communicate with some other school situated in an- 
other locality, and by exchange secure some new varieties of tree 
seeds and introduce these new and unfamiliar trees into the com- 
munity. It will be much more interesting for the pupils to watch 
the growth of a strange type of tree than merely to produce those 
with which every one is already familiar, and, should the experi- 
ment be successful, these new trees may be made to serve a useful 
purpose if they are awarded as prizes for faithful work done by 
individual pupils. Care must always be taken, however, not to 
experiment too much with trees which are not likely to thrive be- 
cause of the climate or other local conditions. 
The Care of the Nursery During Vacations. 
One of the most difficult problems which the school will have 
to solve will be how to care for the nursery during the summer 
vacation. It will not do to leave the young trees which were 
planted during the spring term to take care of themselves through 
the hot months of July and August until school opens again in 
September. Some means must be devised to protect and care for 
them during this time. Just how this will be accomplished de- 
pends largely upon the ingenuity of the teacher and upon local 
conditions.
