THE NECESSITY FOE, GOOD PASTURE, &C. 217 
which are produced by the eruption is very uncertain, an effect 
having been produced only in one instance, and that probably 
arising from the existence of one or more insects in the matter 
used. — 3dly, That the scurf free from all admixture is incapable 
of producing the disease; it may be applied dry, moist, or dis- 
solved, to the hide of a healthy sheep without any effect follow- 
ing. — 4thly, That no effect follows the introduction of the blood 
of a scabby sheep into one that is healthy. — 5thly, That if sound 
sheep are mixed for some days with scabby sheep, they will 
almost to a certainty become infected ; nevertheless, a single 
healthy sheep may continue for two hours in the midst of scabby 
sheep without receiving the infection (this result, however, may 
depend on peculiar circumstances). — 6thly, That the infection 
will discover itself evidently, most probably, between the tenth 
and sixteenth day after it has been communicated, whether by 
the application of the insect intentionally, or in the common 
way, the sound and diseased animals herding together. — 7thly, 
That the scab in sheep of itself is only a local disease, and may 
continue such for a long time without disturbing the general 
health of the affected animal; and that when the health is dis- 
turbed it may be regarded as a secondary effect arising from the 
spreading of the disease, the disturbance of the functions of the 
skin, or from the constant itching caused by the insects, the ex- 
haustion produced by the discharges, or the absorption of such 
discharges into the system of the animal.

[The following observations come in as a fitting sequel to an ex- 
tracted article in our last number, “ Water and its Impurities,” 
and singularly confirms what we have given as a reason for the 
introduction of the former into The VETERINARIAN. Our Ame- 
rican friend will accept our best thanks for them. — E d. Vet.] 
The State of Maine is only just emerging from agricultural 
infancy; yet her farmers have given evidence of their ability to 
produce as good stock, and as good a crop of potatoes, as the 
farmers of her more favoured sister States. What you lack in 
capital and numerical strength you make up for in perseverance 
and industry. As pioneer husbandmen in a section of country 
where some of your most valuable lands were studded with 
forest trees, you have a laborious and difficult task to perform, 
and, in reference to present pecuniary returns, I might add, un-
