the pathology of a common disease of Turkeys, known as 
“ swollen head.” 
A number of diagrams to illustrate the results obtained in 
potato cultivation, in such directions as change of seed, cutting 
sets, sowing large and small sets. 
Among the miscellaneous exhibits at this stand were shown 
specimens of barley damaged by “ Helminthosporium,” the 
disease which is commonly known as “ blindness,” and which 
can be most readily prevented by steeping the seed in Formalin 
solution, one part in about 200 of water. 
South Eastern Agricultural College, Wye, Kent. — At the 
stand at the disposal of this College were shown collections of 
injurious insects, mammals, &c. ; fungi, especially those des- 
tructive to fruit ; various washes used as insecticides and 
fungicides ; a collection of different types of horse shoes, 
dissections of horses’ feet in various stages of disease, and bones 
of the horse’s foot showing disease. 
Photographs of various cross-breeds of sheep experimented 
with at the College Farms, and models showing systems of hop 
training, and various manures, cakes, &c., showing impurities 
were also exhibited. 
The collection of insect pests (exhibited by Mr. F. V. 
Theobald) was in two parts, one of cases showing the insects 
in various stages and the damage done by them, the other living 
examples of some of the most harmful insects feeding on their 
natural food-plant under large bell jars. Amongst these were 
the very harmful apple sucker (Psylla malt), which is such a 
pest in the Worcestershire orchards. The adults only were 
present. In connection with this exhibit was a series of branches 
showing the different substances iised to hold lime and salt 
wash on the trees, and photographs showing the treated trees. 
This wash has been shown in the recent Report on “ Spraying 
for Psylla,” issued by the Worcestershire County Council, to 
be the only successful way of fighting this enemy. 
The other living insects included lackey moths, the 
caterpillars in their tents, the brown tail moth, once so 
abundant in Britain and which occurred again this season ; 
caterpillars of the gold tail moth, and others that had been 
liarrnful during the season. 
Amongst crop pests one bell jar contained living click-beetles, 
the parent of the wire-worm, and another the celery fly. 
Amongst animal pests exhibited were the two warble flies 
{Hypoderma lineata & H. boris), with enlarged coloured 
drawings of each, and the life-history pointed out on labels. 
The exhibition of British mammals of economic importance 
included all those likely to l)e seen on the farm, such as the 
English and Irish stoats, the weasel, voles, mice and vats, the
