To Preserve Wall-Nails from Rusting. — I beg to com¬ 
municate a little valuable information to those who use many nails 
for fastening the Wall Trees. I use cast nails about one inch and 
a quarter long, and heat them pretty hot, in the fire-shovel, over 
the fire, but not red, and then drop them into a glazed flower¬ 
pot saucer, half filled with train oil. They absorb a good deal of 
oil, and thus prepared never become rusty, and will last many years. 
The effluvia of the oil also, for a long time, I fancy, keeps insects 
from the trees. T. B. Buxton.

Lucas’s Self-Acting Force and Lift Pump, for Raising 
Water. (Fig. 34.) This Machine is said to be an excellent con¬ 
trivance for supplying gentlemen’s houses, gar ens, reservoirs, farm¬ 
yards, &c. &c. with water, where, from their elevated situations, it

would otherwise be difficult to obtain. It may be fixed in all situa- 
« * 
tions in which a small supply of water can be procured; its con¬ 
struction is very simple, and not liable to be out of repair, yet should 
that happen, it may be readily adjusted. The appendages can be 
attached to any description of pumps, whether such as are already 
fixed, or otherwise. The w aste of water is very trifling, a very small 
supply being sufficient to work it, which, if requisite, can also be 
raised. Although we have not seen it act, yet a friend of ours, who 
is in the habit of frequently examining it, pronounces it a most va¬ 
luable invention. Conductor.
