conductors ; and a case of points, copper tapes, and necessaries 
for lightning conductors, by Messrs. J. W. Gray & Son, were 
also exhibited. 
Various patterns of meteorological instruments by Messrs. 
Negretti & Zambra and by Mr. J. J. Hicks, were also shown. 
Weather Charts for 8 a.m. and 6 p.m., specially prepared by 
the Meteorological Office, and also a telegram giving the forecast 
for the weather, were posted up each day and lectures were 
given by Mr. W. Marriott on “ Meteorology in Relation to 
Agriculture.”

Cambridge University (Agricultural Department). — The 
Department of Agriculture of this University again sent an 
exhibit consisting chiefly of specimens to show the work which 
is being done at Cambridge in the direction of breeding improved 
varieties of farm crops. Two large sized diagrams, composed 
of specimens showing the progeny of ci’osses between a small 
bearded club wheat and a lax eared beardless wheat, and 
between a black two-rowed barley and a white six-rowed 
barley, formed a conspicuous feature ; and these showed clearly 
the application of Mendelian ideas to the fixing of new types. 
Loaves baked in the University Laboratories were shown to 
illustrate the difference in baking properties between ordinary 
English wheat and the best Canadian wheat ; and side by side 
with this were experiments to show the methods of chemically 
testing flour in order to ascertain its baking value, which have 
been worked out in the University Laboratory. 
Specimens of new varieties of wheat combining English 
vigour and cropping power, with Canadian baking qualities, 
were also shown. 
Another important exhibit was that showing the method of 
raising nist-proof varieties of wheat by hybridization and 
fixation on Mendelian lines. Attention may be called to this 
as supplying the first i-eally definite contribution to the study 
of the inheritance of disease. Results of the greatest economic 
importance may be expected when these experiments have 
been further applied to other crops. 
A number of photographs were also shown illustrating the 
first attempt to apply Mendelian Laws to the cross-breeding of 
sheep. This experiment is only in its preliminary, stages, but 
the results already obtained show that by crossing Suffolks 
and Dorsets and mating first cross rams with first cross ewes, 
a second generation is obtained, in which re-combination of 
the characters takes place exactly as in the case of barleys and 
wheats. 
number of photographs of hybrids between various 
crucifers were also shown, and other photographs illustrating
