long bolts and screw nuts. From four to six of them in ordinary cases 
(more if required) go to make up a boiler; but being all cast to fit exactly 
together, any number of the smaller or the larger pieces, according to the 
size and heating power required, can in this way be firmly put together. 
The form will be most readily understood from the annexed figure. The 
boilers are set directly 
over the fire, which is fed 
from the top. 
One of the advantages 
of this boiler, is its shal¬ 
lowness, as compared 
with tubular boilers con¬ 
structed on the vertical 
plan, which shallowness 
obviates the necessity for 
constructing deep stoke¬ 
holes. The more direct 
action of the flames upon 
the horizontal pipes than 
upon vertical ones, is pro¬ 
bably another advantage, for by the constriction of the upper part of the 
boiler, the tubes are brought directly over the fire, and the flame from the fuel 
curls around each one as it passes upwards. The practicability of adding 
to the heating power, if found necessary, by increasing (or diminishing by 
reducing) the number of rings, may or may not prove a practical con¬ 
venience, as may be the case also with the facility?" with which it is said the 
whole can be taken to pieces, and a new ring added in any part, should acci¬ 
dental injury accrue. Those who have had to form deep stoke-holes in wet 
or badly drained localities, will thoroughly appreciate the advantage of 
avoiding the necessity for deep digging, while securing the quick action of a 
tubular boiler. The setting-is said to be simple and inexpensive. M. 
HORTICULTURAL NOMENCLATURE. 
HAT’S in a name ?” is a question that has often been raised, and 
doubtless as often settled—at least to the satisfaction of the ques¬ 
tioner. Now, whether taken from the political, literary, social, or 
commercial point of view, there is, we apprehend, much in a name ; 
and if we descend from the general to the particular, we fancy that 
from a horticultural point of view it is not a matter of indifference. True 
it is that our greatest poet has said, “ A Rose by any other name would 
smell as sweet,” but we take leave to doubt whether it would always seem 
as fair. We have observed that certain names at once take hold of the
