The time has passed to speculate upon the future of the Pianola Piano. It is here 
to-day as the most successful innovation in musical instruments. 
You may have your choice of four old-established Pianos of high reputation.

Nature’s Lore. 
Up ! up! my friend, and quit your books ; 
Or surely you'll grow double: 
Up! up! my friend, and clear your looks ; 
Why all this toil and trouble? 
Tho sun, above the monntain’s head, 
A freshening lustre mellow, ~ 
- Through all the long green fields has spread 
‘His first sweet evening yellow, 
Books! ’tis a dull and endless strife; 
Come, hear the woodland linnet ; 
How sweet his music! on my life, 
There’s more of wisdom in it. 
And hark! how sweet the throstle sings ! 
He, too, is no mean preacher ; 
Come forth into the light of things, 
Let Nature be your teacher, 
She has a world of ready wealth 
Our minds and hearts to bless— 
Spontaneous wisdom breathed by health, 
- Truth breathed by truthfulness. 
One impulse from a vernal wood — 
May teach you more of man, 
Of morai evil and of good, 
Than. all the sages can. 
Sweet is the lore that Nature brings; 
Our meddling intellect 
‘Misshapes the beauteous forms of things, 
_ We murder to dissect. 
Enough of Science and of Art, 
Close up those barren leaves ; 
Come forth, and bring.with you a heart 
That watches and receives, 
- tion to this rule. 
In a glass jar which is covered over ex- 
Marvels of Pond Life. 
A ROLLING WATER PLANT. 
This little organism is really a marvel, 
for although it is a vegetable, it is able 
-to move by rolling about through the 
water. It is exceedingly small, being 
about the size of the dots over the i's in 
this print. 
When seen with a favorable light, the 
sight is very beautiful. They resemble a 
_pale green transparent glass globe en- 
circled with a fine net, somewhat like the 
wire netting that is around a seltzogene. — 
It is thought they are on the borderland 
between animal and vegetable life. The 
scientific name given to them is Volvox 
Globator, revolving globes. 
Under the microscope we see within 
each revolving globe a number of smaller 
globes also revolving, each one revolving, 
-as 1t were, in its own orbit. 
The volvox are motile, or moviug plants, 
and when examined under high maguifi- 
cation, we are able to discern fine cilia, 
or hairs, the whole ball being covered 
with them, The vibrating of these hairs 
causes the revolving motion, 
All vegetable life loves the light and is 
attracted by it. The volvox is no excep 
If a number be placed 
cepting asmall opeaing where the light 
is allowed to penetrate, they will congre- 
gate against the side where the ray of 
light penetrates, ; ; 
' We will now take one of these globes 
from the jar by means of a small pipette, — 
or medicine dropper, and place it in. an 
animalcule cage, under slight pressure, 80

that it will remain in one place whiie we: 
examine it. Under a medium power of 
the microscope the cilia now comes to 
view, and also the surface of the ball. We 
see that it is cuvered with a network of 
six-sided cells, each cell joined to its 
neighbour by a fine thread running 
straight across from cell to cell, so that 
the whole surface of the globe is seen to 
be a mass of cells held together by the 
thread-like attachment. From the contre 
of each cell two fine hairs, or cilia, project. 
These hairs are the means of locomotion. 
With a higher power objective we find 
. that these hairs are extensions of proto- 
plasm, or living matter. 
From the six-sided cells new spheres 
are formed, but only a few in each globe 
are set apart for that work. These in 
time flatten out, and cell division takes — 
place in the usual way. Whan one eell 
has divided up into four, the parts detach 
themselves from the surface of the globe 
and take their place in the inside cavity 
of the ball, where they continue to mul- 
tiply, and finally develop into revolving 
globes like the parent, so that in each 
plant we see globe revolving within globe. 
As the parent grows and expands, the 
_ threads that hold the cells together are. 
stretched tighter and tighter, until at 
last they can bear the strain no longer, 
and so break away. When this takes 
place, the matured young ones that are 
inside make their escape. ; 
Like nearly all other forms of pond 
life, there is a summer propagation and‘a_ 
winter one. If we examine the volyox in 
the autumn, we see two new kinds of cells 
within the cavity. They are much larger 
than the ordinary ones. One is the male, 
or sperm cell, which, instead of dividing 
into globes, develops into flat discs of a 
red or yellowish color, and finally appears 
as a long shaped cell with a red spot near 
one end and two long cilia. The other 
new cell is. the female, or germ cell, 
which is at first pear-shaped, but finally — 
becomes round and covered with a glutin- 
ous membrane. At this period the sperm 
or male cell breaks up and releases a 
number of animal like creatures called 
antherozoids, which have been developed 
within it. These swim rapidly around ° 
inside the globe until they come to the 
female germ cell. They then penetrate 
the soft glutinous membrane and enter 
and become absorbed into the germ cell. 
This cell is now fertilised, and becomes . 
the winter egg of the volvox. The parent 
breaks up aud the ege sinks to the bottom 
of the water and rests until the spring. 
It then becomes swollen and breaks up 
into a number of cells, each one ulti- 
mately becoming a new plant, with cilia, 
etc., exactly like the autumn parent, and 
it repeats in its own life history that of 
its ancestors. : :

A teacher who was hearing the recita-

the Declaration of Independence signed ? 
- Please, sir, at the bottom,’ answered a 
little boy.-
