important ingredient may be obtained, is the manure. If there is 
a destitution or deficiency of the alkalies, then lime, potash and 
soda are the manures. If the phosphates are absent, then bone 
earth, or some other substance of which phosphoric acid is a part, 
is the manure. 
In the use of any special fertilizer, great care should be taken 
not to give it an undue importance over others equally necessary; 
for the danger is that farmers will over estimate the value of some 
particular manure, and depend upon that alone to supply their 
crops, and restore the fertility of the soil, when it is absolutely ne- 
cessary that all the ingredients, both organic and inorganic should 
be present, in the proportion in which they exist in the healthy 
plant. 
THE COAL MINES AT BLOSSBURG. 
EY J. TREMPER. 
These mines are of very great importance to this state, owing 
to their proximity and the great facility with which the produce 
of them to various parts of it may be conveyed; as the original 
forests, which are fast receding before the spirit of cultivation, are 
removed, the necessity of a convenient fuel will be more sensibly 
felt; already has coal in our cities suspended the use of wood as 
a fuel, as more convenient, less dangerous, and less costly; and 
soon the villages of the interior will be compelled to follow their 
example. As agriculture improves in those districts where lime- 
stone is easy of access, it will have an important influence in af- 
fording a cheap and excellent manure; and where clay prevails 
in the absence of building-stone, of cheaply preparing bricks as a 
substitute; the frame houses of our country being better adapted 
to the climate of Florida than the cold and boisterous winters they 
are vainly expected to protect us against. 
The mines of Blossburg were first explored by Dr. Saynisch, 
owing to whose untiring exertions, much of the natural wealth of 
that region has been developed. The state of New York, by the
