be made, every important feature being inserted, as, for 
instance, the position of a pond, or marshy part, or furrow. 
Then the exact spot in which a plant was found was to be 
noted, its time of flowering, and so on. | 
Members of a class might find it interesting to make a list 
of the plants they found in the spring and summer holidays, 
and then to compare results when returning to school. In 
this way some rough idea would be gained of the flora of 
different counties, and of the plants that inhabit mountainous 
districts compared with those found in flat counties, such as 
Cambridgeshire. Johns’ “Flowers of the Field” is a useful 
book for the identification of plants. 
A great deal of time is sometimes spent in drying plants, 
and getting together aherbarium. ‘This does help one to gain 
a knowledge of many plants, but the time spent in pressing 
inay perhaps be spent to greater advantage in making ob- 
servations such as those that have been indicated here. More 
real knowledge of plant life is obtained by observations of this 
kind than by the making of collections. Miall’s ‘‘ Round the 
Year ” suggests many observations, not only on plants, but on 
Nature generally.
