SOME PROJECT PROBLEMS. 
The home-project plan has not been used sufficiently long to have 
established a very definite order of procedure. Many phases of its 
application are still in process of development, some of them being 
yet in the experimental stage. The followimg problems are suggestive 
of some questions which are being given attention at this time by 
those most interested. The extent to which the plan is adopted will 
depend in great measure upon how well some of these problems may 
be solved. 
Supervision of projects —The success of the home project will de- 
pend to a great extent upon proper supervision. ‘There are so many 
factors which will determine the time taken for supervision that no 
rule can be laid down as to the number of students one teacher should 
supervise. The number is limited, however, when compared with 
the number taken care of with the usual academic, classroom instruc- 
tion. Project work when conducted properly is expensive. As 
summer supervision is most important, schools which can not afford 
to hire an instructor for the full year may well hesitate about adopting 
the plan. Adequate means of transportation should be provided for 
efficient supervision, which means another item of expense. 
The teacher should not scatter his attention over too wide a range 
of projects. He may well center his efforts upon the leading industry
