Jasper, Page, Johnson, Lucas, and Dallas, 5 per cent. or less. In John-— 
son, from 500 to 1,000 hogs died of cholera and quinsy. In Powieshiek, 
an unknown disease swept 25 per cent. of the pigs. In Muscatine, the 
‘‘ anthrax fever” prevailed in some localities, but was not general. In 
Pulaski County, Missouri, one-half the hogs died. Pemiscot and Worth 
lost 20 per cent.; ; Barry, 15 per cent.; Ozark, 25 per cent.; Grundy, 
_ Linn, and Wright, 10 per cent.; smaller losses from cholera, pneumonia, 
&c., were reported in: Caldwell, De Kalb, Bolinger, Callaway, Daviess, 
Moniteau, Perry, Carroll, Stoddard, Marion, and Lincoln. In Holt 
County, one-half the young hogs were destroyed by a singular disease, 
the prominent symptoms of which were cough and swelled throat; one- 
third of the older hogs died from another malady, characterized by stu- 
pidity, loss of appetite, &c., sometimes obviated by merely changing the 
animal’s quarters and bedding. The above symptoms strikingly re- - 
semble the epizooty. In Nodaway, kidney-worms destroyed 15 per cen. 
of young hogs. But two counties in Kansas—Brown and Chase—re- 
port losses, and in both cases light. In Nebraska, Cass County lost 10 
per cent. ; "Richardson and Pawnee, a few cases each. In Alexander 
County, California, some Kentucky hog-pedlers imported diseased ani- 
mals, which infected others there and in other counties. In Mendocino 
County kidney-worms were somewhat troublesome. 7

THE TOBACCO-WORM.—The tobacco hawk-moth or ‘“ horn-blower” of 
Maryland, Macrosila (Sphinx) carolina, Linn., is a large moth, the cater- 
pillar of which, commonly known as the tobacco-worm (Fig. 3) in the 
Middle States, is very destructive to the leaf of the tobacco-plant, when 
the worm is young, by eating holes in the leaves, thus spoiling them for 
use as wrappers for cigars, and when old by devouring the whole of the 
leaf itself. These worms appear of all sizes, during late summer and 
autumn, in the tobacco-fields in Maryland, the first brood of eggs hatch- 
ing in May or June. 
During the last season the Department has received numberless letters 
on the subject of their ravages, desiring information concerning their 
habits, and the best remedies that can be suggested for their destruc- 
tion. We shall therefore give a short description of their transforma- 
tions from the egg to the perfect fly. The egg is deposited singly on the 
leaf of the tobacco pr tomato plant, and the young worm when first - 
hatched out by the heat of the sun commences to eat holes in the leaf 
of the plant, and sheds its skin several times before attaining its full
