The whole of the above may be modified in various ways. The 
chief results are the great seasonal movements of lambs into the Area 
for the winter, and out again six months later; and the equally great 
movements to and from the mountains, and from farm to farm. There 
are also considerable movements connected with fairs, with shearing, 
and with dipping. A detailed account of the local farming will be found 
in the forthcoming Report on the Economic Survey of the Aberystwyth 
Area by Mr J. Pryse Howell. Of the 250 farms and holdings from which 
data were obtained we may neglect 75 on which either no sheep were 
kept, only wethers were bought in to fatten, or the data obtained were 
unsatisfactory. This leaves 175 from which to draw conclusions, and 
these fall into three categories : 
A. Flocks always kept at home (no movement) ... 68 
B. Flocks from which sheep are moved only within 
the Area surveyed (short to medium movement) 77 
C. Flocks from which sheep are moved to places 
without the Area, or moved into the Area from 
without it (medium to long movement) ... 30 
Total ... 175 
If these classes are now examined in turn, using the data given me 
by the farmers and shepherds, we discover differences in the degree of 
infection as follows: 
A. Out of a total of 68 flocks only 15 complained of Gid (locally 
known as Bendro, from jpen = head, and tro = turn, both words mutate 
and thus become bendro), and in all cases the infection was shght. 
The percentage of infected flocks in this category is 22. Of the 
15 flocks affected, seven had a mountain run adjoining, two were inter¬ 
sected by high roads (from which sheep are seldom effectively excluded), 
one grazed on an adjacent common, and another, in addition to a high 
road, walked hound puppies, thus increasing the number of dogs and 
the possibilities of infection. It is presumed that sheep grazing along 
a high road run increased risks of infection from grass fouled by dogs. 
No definite figures are available for these 15 flocks, “a case now and 
again” being usually reported; probably -5 % would be fairly accurate. 
B. Seventy-seven flocks come within this category and of these no 
less than seventy complained of Gid, or 90-9 % of the flocks. Many 
farmers were uncertain as to the actual number of cases and while 
complaining of trouble, stated “ a few,” “ one or two,” “ several,” or used
