abreast of e€ach other, he places two 
strong beams, which he calls depressers, 
across the three vessels, which beams 
may be placed twelve or fifteen feet 
asunder; but equidistant from stem to 
stern of the boat. The loaded vessel has 
fixed ina strong keeison, two powerful 
screws, and higher as to length than her 
gunwale: the beams, or depressers, 
having holes bored in the centre of them, 
receive the heads of the two screws; two 
eapstans, with bars being fixed in the 
head of each screw, the vessel which is 
loaded, becomes by the action of these 
elevated ‘screws vradually raised, while 
two beams are laid across the vessel and 
lightners, so that, by raising the loaded 
vessel, and depressing the lightners at 
‘the same time, the weight is divided on 
the three. When the shoals and diffi- 
culties in a river are so greatin places 
‘that the. lightners cannot enable the 
jJoaded vessel to pass, then he uses a 
Dumber of water-troughs, called move- 
2ble weirs, of which the first is fixed with 
‘a kedge anchor on the opposite side of 
the river, when the vessel 1s to pass the 
shoal; and by attaching 1a number of 
these moveable weirs to each other, in a 
d@iagoual position, and by placing a 
tarpauling along them to prevent the 
scape of the water, he sinks the said 
weirs by weights in the river, by which 
‘means he directs the current of the river 
inte.so-narrowa‘channel, that the in- 
<rease of water wili so deepen the shoal, 
that the vessel and apparatus will be 
enabled to pass the -said shoal, and 
thereby continue her course. When the 
stream és too narrow for the barge, and 
dightners both to float, the barge may be 
buoyed up so as to be clear of the bot-, 
tom, when the lightners must be stranded. 
In this case, two iron wheels are requi- 
site at the ends of the beams, to run in 
‘a trough affixed above the gunwales of 
the trough in the centre, and by secur- 
“ang the cable by anchor, or otherwise, the 
vessel may, with lier windlass, be warped 
». WIESOR’S, (PALL-MALL), for a fired 
Telegraphic Light-house, &c. for Sig- 
nals and Fntelligence, to serve by 
Night and by Day, §c. 
The tight-house consists, first, of a 
plain or hollow mast, either fixed or 
caised, and lowered at pleasure, accord- 
ing to the local situation. A lanthorn, 
of a large size, is fastened at top, which 
may be furnished with lenses, and may 
be supplied with gas or oil, and the lights

may be multiplied to any number, and 
arranged in different divisions above each 
other, so as to leave some visible space 
between them; for if only one rew, or 
circle of light is given, it might, at a 
distance, be mistaken for a star: if only 
one row, circle, or division, of Jight w 
given, a pure gas flame or oil-lamp, 
should be fixed at certain height 
above the lanthorn, In the present 
light-house, the gas burns in the form of 
a vane, or weather-cock, shewing the 
direction and variation of the wind in 
the darkest nights, which no rain, nor 
any storm, can extinguish: but the chief 
atility consists in the application of it 
for signals .and telegraphic dispatches. 
By Mr. Winsor’s invention, one central 
telegraph may correspond with awy 
number of surrounding ones, by only re- 
serving a distinct signal for preparation 
for each: whereas the telegraph, now ia 
use, will only serve for one direction, ‘or 
one point, in the compass, and there must 
be as many central ones, as there are 
Next surrounding telegraphs. 
Another point is, that the telegraphie 
light-house is made moveable to corre~ 
spond at different parts of the sea-coast, 
orany where, where no fixed telegraphs 
are erected; for instance, a vessel at sea. 
in distress fires guns, or makes other sig- 
nals of distress; a moveable telegraph 
may be brought by a horse and cart, 
nearest the opposite point, \to give sig- 
nals that relief is preparing, and to give 
directions of any kind to mariners in dis- 
tress. The inventor says, his telegraph 
may be of use to armies,during battle, 
by serving to convey orders from the 
commanding general to any, and -the 
most distant, corps, whereby time is 
saved, and a variety of maneeuvres can 
be executed against the enemy with the 
greatest celerity. ‘The machie is con~ 
“structed on the principle of the lazy 
tongs, which shut up m acart, and is 
raised to any length, from thirty to sixty 
feet, with ease and swiftness: it may 
follow the general, and become, more 
serviceable than many aide-de.camps,
