Dear Mr. Jones,—Mr. Gilzean arranged with me before he left, to carry out the 
experiments with Manures on Ruimveld, so as to ascertain whether the prevalence 
or the intensity of Fungus disease is in any way influenced by Manures. This has 
been done, and I enclose for you as Chairman of the Agricultural Committee the 
table of results, 
I superintended the weighings of the canes and the separation of the diseased 
canes. I considered as diseased all canes showing any external sign of rind fungus, 
I ascertained the percentage of the canes diseased by numbers and also by weight. 
You will notice that all the fields were affected by the disease, and that its intensity 
appeared to be largely,in proportion to the nitrogen in the Manures applied.
