in tuning their voices to many a glee over their 
well-tilled pails. A beautiful herd of cows with 
these harmonic bells, attuned with art, grazing on 
their sunny green slopes, interspersed with copses 
of wood and sylvan clumps, could never be observed 
by a lady of refined taste, without awakening asso¬ 
ciations full of interest and of the highest gratifica¬

BUYING APPLES. 
Two boys, James and Robert, received six cents 
each to buy apples. James purchased two dozen 
of small Lady Apples, one inch in diameter; but 
Robert, more considerately, bought with his money 
two large Pippins, three inches in diameter. On 
their way to school, the question rose, which had 
made the best bargain. James contended, that, as 
he had the most apples in number, and as they 
made a larger pile when placed together, he had 
spent his money to the best advantage ; but as Ro¬ 
bert differed from him in opinion, it was agreed that 
the matter should be referred to their teacher at the' 
first convenient opportunity after they should arrive 
in school. 
The teacher, after hearing the statement of each, 
requested James to compute the cubic contents of a 
globe one inch in diameter, and then as the apples 
resembled small globes in their form, to determine 
the number of cubic inches, in 24 little globes of 
the same size. James, being good at figures, went 
immediately to work, and soon ascertained that the 
contents of a one-inch globe were equal to 5236- 
10,000th part of a cubic inch, and that 24 such 
globes contained a little more than 12k cubic inches, 
w T hich his teacher told him was about the amount 
of solid matter his apples contained. Robert, mean¬ 
while, had taken the hint, and calculated the con¬ 
tents of a three-inch globe, which he found to 
contain more than 14 cubic inches, whence it was 
evident, that he had expended his money to more 
than double the advantage. 
James, chagrined at this, and determined never to 
be caught so again, set himself to work and made 
the following table, by multiplying the diameter of 
each apple or globe three times into itself, and the 
products by the constant number 0.5236.

FOG, VAPOR, CLOUDS, RAIN. 
Q. Where does all the water of springs, 
brooks, and rivers, finally run ? 
A. It runs into the sea or ocean. 
Q. Do these streams raise the surface 
of the sea ? % 
A. By no means; the water goes back 
again to the land. 
Q. In what form does it do this ? 
A. In the form of clouds and rain. 
Although the water of the ocean is i 
salt, rain water is not so; because only 
the fresh part rises in the form of 
vapor. 
Q. How are clouds produced from the j 
sea and other bodies of water and. 
land ? 
A. By fog and vapor, which rises from 
their surface. 
The clouds formed in this manner, 
are driven by the wind over different Fog rising from the Ocean and forming Clouds.- 
portions of the earth; and in this way the earth 
is kept constantly supplied with refreshing showers 
of rain. 
Q. What causes fog and vapor to rise ? 
A. The warmth of the earth and sun. 
Q. What appears to be the order in wh 
rain, springs, &c., are formed ? 
A. The rain forms springs; 
The springs form rivers; 
The rivers run into the sea.

ich clouds. 
“ But there went up a mist from the earth and watered 
the whole face of the ground.”— Bible. 
Q. What is this process called ? 
A. It is called evaporation. 
The “drying up” of water, as we term it, is 
called evaporation, as steam rising from a vessel 
of hot water. Hay is made from evaporation. 
The sea gives vapors; 
The vapors form clouds; 
The clouds give rain again. 
“ All the rivers run into the sea, and yet the 
sea is not full; into the place from whence the 
rivers come, thither do they return again.”— Smith's 
First Book of Geography.
