growth and purpose . Collect, as in the other 
grades, a great variety of twigs, especially of hick¬ 
ory, lilac, Balm of Gilead, cottonwood and syca¬ 
more. To avoid an over abundance of brush and 
litter, request the pupils to cut the twigs only three 
or four inches long and bind them into bundles of 
a dozen twigs each before bringing them into the 
school room. As to position, buds are either ter¬ 
minal or lateral. The lateral buds are borne upon 
the sides of the branch and are usually found in the 
axil of the leaf. There are superposed buds and 
adventitious buds on some plants, but it will be as 
well to avoid the necessity of studying either in 
this grade. 
The arrangement of buds is dependent upon the 
arrangement of leaves. Compare terminal buds 
with axillary buds, and account for the greater 
growth from the terminal bud. 
Cut cross-sections of terminal buds and require 
the children to draw cross-sections greatly enlarged, 
so as to show the arrangement of the leaves and 
scales. 
Cut cross-sections of lateral buds and draw. 
Draw stems containing leaves with buds in axils, 
and also terminal buds showing relative sizes. 
Draw sycamore bud with the protecting leaf just 
pulled off at one side, with cup in base of petiole 
in full view.
