The Aberystwyth Area 
Examination of a number of sheep walks during May—June only 
resulted in the discovery of one lot of proglottides and that among 
lambs recently brought up from the lowlands (June 1915), and, so far, 
I am without positive evidence of these worms above 1000 ft., and the 
causes of presence and absence are still obscure. I have been told 
by some shepherds that they see the worms “now and again”; others 
have never noted them, while still others say “ common.” I have also 
received reports of tape worms from South Cardiganshire, Carmarthen¬ 
shire and Pembrokeshire where they were said to be very abundantly 
seen in the slaughter houses. 
Reports from Aberystwyth and local men state that lambs of only 
six weeks may be heavily infected with worms of great length; that 
lambs killed in autumn contain fewer worms and those much less in 
length; whilst in ewes the worms are comparatively rare. 
Lambs from some farms appear to be always free. It is of course 
noteworthy that only lambs considered to be fat reach the slaughter 
houses, the worst cases being retained upon the farms. I have frequently 
observed enormous masses of Moniezia littering the floors of the 
abattoirs and noted the eager manner in which poultry will eat them. 
It seems very desirable that these species of Moniezia should be care¬ 
fully investigated and the Aberystwyth Area would be very suitable for 
such work. 
“Husk” (Verminous Bronchitis). 
Forty farmers complained to me of “Husk” and though I feel 
certain that a number of these cases were caused by the Nematode 
Strongylus filaria I would not like to affirm that this parasite was the 
cause of them all. 
Most of the complaints came from farms situated on damp or clayey 
land, and in many cases the calves had been allowed to graze in a field 
containing an undrained or swampy patch, or one in which the drains 
had become blocked, this causing very similar conditions. It is worthy 
of note that during a drought, calves are not infrequently allowed to 
graze aftermath near streams, etc. or in low lying fields where the growth 
of grass has continued, while the fields usually used for calves have 
become very bare. As a result of this, husk is reported from these 
farms while others are free. Those farmers who take precautions and 
care, who keep their calves indoors until the sun has dried the grass 
and away from swampy land, etc. and adopt other reasonable means, 
seldom have cause for complaint. In one case, on the Dyfi Flats, where
