322 NATURAL HISTORY OF THE FARM 
and gardens; also, if convenient, one or two water-grasses, 
such as cut-grass, manna-grass or reed. Weekly observa- 
tions should be made through the term on the activities of 
the whole plant—what it is doing in leaf or stem or flower or 
fruit production; what it is doing below ground in the 
way of production of stools or offsets; when starting growth 
or second growth; when distributing seeds, etc. 
For record, these observations may be entered in the 
columns of a cross-ruled table, the left-hand column being 
reserved for the names of the grasses, and dates being written 
at the top of the other columns in proper order. Names of 
the grasses, if needed, will be supplied by the instructor 
when a flowering or fruiting specimen is furnished for 
identification. Following the name of each kind of grass, 
there should be written, in the proper date columns, the 
observations made upon it. Footnotes may include any 
observations for which there is not room in the table. 
Optional Study 12. A Calendar of Summer Wild Flowers 
This is a continuation, through the summer season, of the 
observations on spring flowers, outlined in Optional Study 8 
on page 229, and may follow the plan there outlined. For 
the second table-heading, ‘Relation to leaf-unfolding,” 
substitute: “Form and size of flower-cluster (diagram, 
and give measurements)”’.
