THE MORGAN HORSE, “ BLACK HAWK.” 
from the spiral thread g, and forces it into the discharge 
spout k. 
The grain, during its passage through the annular 
space/, is acted upon by heat on both its enclosing sur¬ 
faces at the same time; the casing C being acted upon 
directly by the heat of the furnace, and the casing B 
by the hot air and gaseous products of combustion in 
their passage from the furnace through the annular flue 
space e, to the chimney. 
It will clearly be perceived, as a very valuable fea¬ 
ture in my kiln-drying apparatus, that the heating sur¬ 
faces over which the grain passes, are regularly and 
constantly increasing in temperature, from the point 
where the grain enters the circular chamber A, to that 
where it is discharged out of the annular space/; this 
feature, combined with the constantly progressive rota¬ 
ry motion, causes every particle of grain to be equally 
operated on by heat, without danger of injury from 
scorching, if proper attention be paid to the furnace. 
The red arrows in fig. 1, represent the course of the 
wheat from the receptacle w, through the chamber A, 
and annular space/, to the discharge spout A; the black 
arrows represent the course of the hot air and gaseous 
products .of combustion frdm the furnace to the chimney. 
I design using my rotary cylindrical grain-dryer, not only 
for kiln-drying grain of all J^inds, but also for drying malt, 
salt, and every other substance it can be used for, and 
for the roasting of coffee. 
Having thus fully described the construction and ope- 
r'tion of my rotary cylindrical grain dryer, what I claim 
herein as new, and desire to secure by letters patent, is 
tne uniting the cylindrical casings A, B, and C. with 
each other, and combining them with the furnace J, in 
such a manner as to form a circular heating or drying 
chamber A, within the inner casing A; an annular 
space or drying chamber /, connected with the same 
between the outer casing C. and central casing B, and an 
annular flue space e, between the central casing B and 
inner casing A , substantially as herein set forth. 
I also claim the giving the grain or other substance 
acted upon, a constantly progressive rotary movement 
from the front to the rear end of the circular drying charn 
ber A .—conducting it into the annular space or drying 
chamber/, and returning the same by a reversed move¬ 
ment to its front end, and discharging the kiln-dried 
grain at the spout k, by the action of the projecting 
spiral thread d , connecting pipes h , h , and spiral thread 
g , combined and operating substantially in the manner 
and for the purpose herein set forth. Sebre Howard. 
“ BLACK HAWK.” 
Editors of Cultivator —About two years since I 
furnished you a drawing of Messrs. Hills’ horse “ Black 
Hawk,” with a description of that animal, and the Mor¬ 
gan stock in general; all of which was published in the 
June number of your periodical, and which elicited cor¬ 
roborating remarks from connoisseurs of the horse. 
Too much, in my opinion, has not been said in praise 
of this perfect “ Yankee Harness Horse,” and the Mor¬ 
gans in general. His stock, most of them, outdo their 
sire in size. I saw several colts of his get. coming two 
this season, weighed, some months since, their weights 
varying from 800 to 1000 pounds. These colts exhibit 
great action, and are sprightly, mild and attractive. 
By the request of the Messrs. Hill, I have sent an¬ 
other drawing of this noted horse, exhibiting him in 
harness, to the engraver; the cut I presume will be fur¬ 
nished you this month, and I hope to see a perfect figure 
and representation of the animal. I am happy to in¬ 
form you that he will, be on the ground at your next 
State show, together with some of his stock.
