ARBOR DA V MANUAL. 
So, whatever the plant may be — a great forest-tree or a spear of grass — its- 
cells are made of carbon and water. The whole tree is made of these cells,— 
trunk, roots, branches, leaves, flowers, fruit. 
Look at a great oak tree. Can it be that that immense plant is made of 
nothing but a mass of tiny cells not larger than the dot of an i —and not so 
large? It can be. It is so. 
PUSSY WILLOW. 
'HE brook is brimmed with melting snow, 
1 The maple sap is running, 
And on the highest elm a crow 
His black wings is sunning. 
A close green bud the Mayflower lies 
Upon its mossy pillow; 
And sweet and low the south-wind blows, 
And through the brown fields calling goes, 
“ Come Pussy! Pussy Willow ! ” 
Within your close brown wrapper stir; 
Come out and show your silver fur; 
“ Come Pussy ! Pussy Willow ! ” 
Soon red will bud the maple-trees, 
The bluebirds will be singing, 
And yellow tassels in the breeze 
Be from the poplars swinging; 
And rosy will the Mayflower lie 
Upon its mossy pillow; 
But you must come the first of all, — 
“Come, Pussy!” is the south-wind’s call,-— 
“Come Pussy! PussyWillow!” 
A fairy gift to children dear, 
The downy firstling of the year,— 
Come Pussy! Pussy Willow!
