learned from Mr. Look that in the month of August, 1855, he had 
thirty barren cows, varying in age from four to eight years, at pas- 
ture on a particular field — a piece of old feeding-ground — which 
had been going on to his perfect satisfaction ixp to the time of th& 
appearance of the disease. These animals had been bought between 
Christmas and May-day, about which time they were turned out to 
graze. Ko indications of ill-health preceded the attack ; but sud- 
denly and within a few days thirteen of them died, some being 
found dead a few hours after being believed to be in perfect health. 
The remainder of the animals were at once disposed of, and withiik 
a day or two of the sale several more of them became affected and 
died. After their removal the pasture was fed with sheep during 
the latter part of the summer and the succeeding autumn, and a 
great many losses also occurred among these animals from the same 
disease. 
The field in question, which, for distinction, I will name No. 1, 
is apparently a piece of good grazing ground. It lies on ridges, the 
valleys between which act as surface-drains. The greater portion 
of it is sufficiently dry, but the lowest parts would be improved by 
under draining. It contains twenty-seven acres, and is bounded ou 
one side by the river Yeo, from which the animals obtain their 
drinking-water. It has been regularly fed since 1844. No dif- 
ference was detected by me between the grasses it bears and those 
growing on the contiguous pastures, which hitherto have been per- 
fectly free from the disease. 
In the spring of 185G some more cattle were turned into this field, 
and in the course of three weeks one of them died. The others were 
immediately removed, and with one exception they all did well. 
The animal thus alluded to died within two or thi-ee days of its 
removal. 
The field was then shut up for mowing, and after the haj'-makiug 
it was stocked with about a dozen luUs, all of which went on well. 
They were turned in almost immediately after the removal of the 
hay, and consequently before the growth of much after-gi-ass. 
In 1857 the same plan of mowing and stocking the after-grass- 
with hulls was adopted, and without any loss. 
In 1858, and also in 1859, the field was partly mown and partly 
fed with sheep. An occasional death took place among these 
animals. 
In 1859 the disease appeared on another part of Mr. Look's farm 
— field No. 2, situated at a considerable distance from No. 1, It 
broke out among eleven feeding o.xen, four of which were at once 
slaughtered. Tliis also is seemingl}' a good piece of grazing land, 
and the animals pastured upon it have ready access to a brook of 
pure water. 
In 18G0 No. 1 was fed with sheep entirely, and the deaths being 
numerous, the animals were removed ; after which the field was 
skimmed over with the scythe, and then fed with hulls, and again 
Avithout any loss.
