Report on Liver-Rot. 
159 
worms measured by myself were 20 feet longf ; that was in the 
months of May and June 1879. There would be at least three 
joints in each, and 50 eggs in each joint, the quantity of eggs 
voided must amount to millions in a field ; but the same land 
in 1880 did not affect the sheep with tape-worm. Then, 
again, how is it that in the summer of 1879 thousands of 
lambs in this district became affected witli the throttle-worm, 
and the same lands scarcely affected the sheep at all in the 
summer of 1880. Tliere must, hence, be some special law in 
action in certain seasons favouring the development of these 
worms." 
Mr. C. W. Tindall, Aylesby Manor, Grimsby, manages 1700 
acres, two-thirds arable, one-third pasture, the land being high 
wold, loam, clay, and marsh. About 1000 Lincoln sheep are 
kept, grazing on the old pastures and clovers in summer, folded 
on turnips in winter, receiving besides cake and other con- 
centrated food ; salt has been used since 1879. Certainly for 
half a century the farm has never rotted sheep ; the marshes are 
not liable to flooding, but for several months during the summer of 
1879, owing to the continuous rain, they were in places ankle deep 
in water. The cattle as well as the sheep grazed there between 
July and October have been fluked ; 400 ewes were affected ; 
some are stated to have suffered earlier and worse than others ; 
but the aggravating circumstances are not known. Mr. Tindall 
is unaware whether the hares and rabbits are affected with 
flukes. The following is his statement of the Aylesby visi- 
tation : — " On August 6th, 1879, we sent from our Wold Farm 
190 feeding ewes to marsh land in the parish of Immingham, 
also 180 breeding ewes to marsh land in the adjoining parish 
of Stallingboro', both very similar land, both lying low. The 
190 Immingham ewes came to wold turnips on the 9th of Sep- 
tember. For a time they did well, but in the first week in 
December I found they were going all wrong, and had them 
examined, when they were declared affected with rot. We ran 
10 through the gate and had them killed, and found them as 
bad as needs be. Consequently we drew 100 of the worst and 
killed them at home, sending the carcasses to London ; the 
rest we sent off alive to Manchester. This was the third week 
in December. The ewes that went to Stallingboro' came up on 
the 6th of December, so at the same time we had them examined, 
and drew out 10 of the worst-looking, and sent them to be 
killed. Finding seven of them quite sound, so far as we could 
tell, I would not let any more be killed. From the above you will 
notice that the Immingham ewes were down only six weeks and 
all rotten, whereas the Stallingboro' ewes, under circumstances 
exactly the same, were down 16 weeks, and at this time were
