An abstract, with notes, from a paper by Burek published in the “ Javaasche Courant.” 
States the disease is due to a fungus, Hemileia vastatrix , which attacks the lower surfaces 
of the leaves and gains entrance to the interior through the stomata. The spores develop 
only in water and in darkness, light and moisture together being destructive to them. The 
infection of the leaves is described and suggestions are made for cure or prevention. The 
third pair of leaves on each branch, is the one first attacked. If taken in time and the dis¬ 
eased spot punctured with a needle having on its tip a small amount of sulphuric acid, or if 
it be cut out with a pair of scissors made especially for the purpose, the disease can be 
checked. It can also be prevented by spraying with copper sulphate, sulphate of quinine 
and tobacco water. The expense of treating plants is very slight, not exceeding 1| guilder 
cents each from the time of sowing until coming into bearing. Planting hedges so as to inter¬ 
cept the wind is also recommended. (J. F. J.)

Report from Graaff-Reinet states that rust is injuring wheat, some farmers reporting one- 
third of a crop lost. At Humansdorf nearly all soft wheat perished with rust, but hard 
wheat, such as Blaauw-Horn withstood the rust. Oat hay was injured by rust. At Peddie 
rust is reported bad on hard wheat; beans “rusted” in some parts of the district. The 
earlier varieties of grapes “are affected with rust.” At Steynsburg and Uniondale rust is 
reported on wheat to some extent. (W. T. S.)

Additional reports from seed inspectors are given. Rust is reported as destructive at 
Dooren Kloof and Tarkastad in the eastern districts. At Dooren Kloof “the rust was 
worse this year than it has been for vears; several people just, burnt oft’ their wbeatto clean 
the lands; others cut it off for bedding for their horses. Even the best wheat reaped was 
rusty.” (W.T.S.)
