Zoological Department was represented by the Insect Diagrams, 
prepared by the late Miss Ormerod and her sister, and by four 
cases of injurious insects with illustrations of injuries. These, 
with two similar cases of forestry pests shown in the Forestry 
Department, form part of a cabinet which is now in process of 
formation by the Society’s Zoologist (Mr. Cecil Warburton), 
and which is open to the inspection of Members at Hanover 
Square. 
The exhibits from the Woburn Experimental Station, 
prepared by the Society’s Consulting Chemist (Dr. J. Augustus 
Yoelcker), were however the principal feature of the Society’s 
own share in the Exhibition. They consisted mainly of experi- 
mental crops grown in pots at the Pot-culture Station, together 
with illustrations of certain of the plots on the Experimental 
Farm, and of the produce obtained. 
1. Canadian Wheat. — Pots, with growing crops, were 
shown, exhibiting the “ Red Fife ” variety of Canadian wheat 
in comparison with English “ Nursery ” wheat, both being 
grown on the same soil and under the same conditions. The 
wheat in each case was spring-sown. This trial is being 
carried out on the field scale also. In 1903 the yield of 
Canadian wheat was about five bushels per acre lower ; but the 
quality of the corn was better and fetched in the market about 
3s. per quarter more than the English wheat. 
2. Large and Small Seed for Sowing . — The difference 
between using, in the one case, large and plump grains and, 
in the other, small grains, was illustrated with barley by two 
pots, in one of which twelve large grains had been sown and 
in the other twelve small grains. There was, at the time of 
exhibition, little difference to be seen between them. 
3. Improvement of Fen Land . — There were several pots, 
with barley growing in them, to show how a pot-culture station 
might be put to good service in ascertaining what are the 
requirements of a soil from a district quite different from that 
where the station happens to be located. The soil in question 
was from regular fen land in Cambridgeshire ; an analysis of 
it gave — phosphoric acid, *12 per cent.; potash, *23 per cent.; 
lime, 3*23 per cent. In such a soil the amount of organic 
matter would, of course, be very high, and this might tend to 
produce acidity. It was shown how, by the addition of lime, 
at the rate of 1 ton per acre, on a soil like this (which might 
be said to be well supplied with lime were it an ordinary soil), 
the yield of barley could be considerably increased, and, 
further, that the physical condition of the soil was much 
improved. The soil was rendered much more friable and 
showed less tendency to “cake”; the organic acids had, no 
doubt, been also neutralised. Even more striking was the
