310 Printing Press for the Blind.—Mount Vesuvius. 
scarcely larger than a walnut, last winter took fresh made lime 
from the kiln, slacked it with water, and (without allowing time 
for its caustic quality being injured by imbibing fixed air) well 
dressed the trees, applying the lime with a brush. The result 
was, that the insects and moss were completely destroyed, the 
outer rind fel! off, and a new, smooth, clear, healthy one formed ; 
and the trees, although some twenty years old, have now a most 
healthy appearance. 
It will readily occur to the reader, that the same treatment 
may be extended to other fruit-bearing trees, and probably with 
a similar beneficial result. 
PRINTING PRESS FOR THE BLIND. 
A Journal printed at Geneva thus announces a very interest~ 
ing invention:—A Press For THE BLinp.—A lady deprived of 
sight from her birth, but distinguished for her wit, her talents, 
and good temper, conceived that it might be possible to com- 
municate her thoughts to her family and friends by means of 
printing, if some skilful mechanic would invent for her a press, 
and give her the necessary instruction to make use of it—the ap- 
plication and patience for its accomplishment becoming after- 
wards entirely her own. She addressed herself to our country- 
man Mons. Francois Huber, the celebrated historian of Bees, to 
whom she had the advantage of being related; in addition to 
which, @ community of misfortune {for he also is blind) increased 
the interest he had in gratifying her request. ‘Thereupon his own 
genius, and that of his servant Claude Lechet, a man endowed 
with the highest degree of natural talent for mechanics, were 
strongly excited. ‘They went to work, and the press was in- 
vented ; and being finished by Claude, who sent with it a col- 
lection of types to the amiable suggester of the plan, she soon 
made herself mistress most completely of this invaluable means 
of communicating her ideas. We have seen a letter of 33 lines 
addressed to her happy benefactor, composed, and printed by 
herself with common ink, without a literal error, or a single ty- 
pographical irregularity.” —Courier de Londres, April 5, 1822. 
ERUPTION OF MOUNT VESUVIUS. 
Naples, Feb. 25.—On the 13th of this mouth two loud subter- 
rancous detonations were heard in the neighbouring communes of 
Vesuvius ; these phenomena usually precede each eruption, From 
the night of the 16th to the 17th the detonations were renewed with 
violence, and were heard from hence. On the following day it 
emitted a thick smokes on the 19th it began to throw up a shower 
of cinders and stones, and soon after fragments of inflamed lava. 
This eruption again covered the whele extent of the crater, a
