pot a variety excessively susceptible to this disease, with its 
foliage and stems badly attacked. These varieties had been 
crossed together two years previously, and in a third culture 
numbers of the descendants of the hybrid were shown. Some 
of these were excessively diseased, whilst others were entirely 
free from rust. All three cultures were grown under the 
same conditions. 
Specimens were also exhibited from the field plots of these 
same hybrids showing fully developed plants. The resistant 
parent has dense ears ; the susceptible has lax ears. Among 
the hybrids were dense-eared forms with badly infected 
foliage and stems, and amongst the lax-eared forms were 
some which were disease-resisting. It was thus shown that 
immunity and susceptibility to yellow rust could be trans- 
ferred from one type to the other. 
A considerable group of exhibits dealt with the formation 
and improvement of pastures. The Abbotsley pastures 
furnished material for a diagram which showed how slight 
may be the correspondence between the original seed mixture 
and the composition of the herbage of the resulting pasture. 
Turfs from the University Farm showed the effects of suitable 
manuring and of neglect on a five-year-old pasture ; and a 
second series of turfs from a poor Boulder Clay pasture at 
Cransley, in Northamptonshire, showed how useless is the 
attempt to enrich such pastures by cake-feeding, or to improve 
them by liming, until the soil has first had a dressing of from 
8 to 10 cwt. per acre of basic slag or superphosphate. In 
sharp contrast to the Cransley turfs, a third set from the north 
of England was introduced to show the class of soil which 
must be limed before manuring is resorted to. 
South Eastern Agricultural College, Wye, Kent. — As in 1904, 
this College sent its collection illustrating the chemical and 
physical properties of typical soils in Kent and Surrey, in 
relation to the crops for which they are best adapted ; also 
samples of nitrogenous manures for hop-gardens. A model 
and diagrams illustrated experiments on the digestibility of 
feeding stuffs. Fungoid pests of agricultural plants and fruits 
were illustrated. Living and dead specimens were shown 
of injurious insects. Those alive were exhibited in gauze- 
covered glass globes feeding on the plants they respectively 
injure. Labelled with their common and systematic names, 
and with brief descriptions of their characteristic habits, these 
exhibits made an interesting and instructive object lesson, 
especially to those occupied with fruit growing. The pests 
included the lackey moth ( Clisiocampa neustria ), the goose- 
berry saw fly ( Nematus ribesice ), the apple saw fly (Hoplocampa 
testudinea ), the little ermine moth ( Hyponomeuta malinella),
