tree one pound of sulphate of iron in 25 gallons of water ; also give 
to the ground a dressing of three to four pounds of bonedust and 
one pound of sulphate of potash per tree, and avoid dry blood 
or orzanic nitrogen fertilisers. Make sure that drainage is good. 
Briack Spor or Crrraus Fruir (Phoma citricarpa, MeAlp.)— 
This disease, known also as anthracnose of citrus fruit, is on the 
list of prohibited diseases, and fruit showing signs of them are 
destroyed at the ports of entry. 
For the information of growers, and also of the officers in charge 
of the disinfection sheds at the ports of entry, I reproduce 
from Mr. D. McAlpine’s Monograph of Fungus Diseases of Citrus 
Trees in Australia, a summary of the description of the disease. 
The disease, it is stated, has not been met with in Victoria, 
but it is quite common on oranges, mandarines, and lemons sold in 
Melbourne and suburbs, and imported from Sydney. 
The fruit is affected by spots, round and sunken, and of a 
dark brown colour ; at first, whitish or greyish towards the centre, 
but ultimately becoming of one uniform tint. They are either 
isolated or run together in confluent brown patches. These are 
pustules which allow the escape of spores, which may be wafted 
by the wind, or carried by hands, clothing, insects, animals or empty 
cases. Thus is the disease rapidly and widely spread. It bears 
some resémblance to another black disease of citrus fruit called 
“*Melanose,”’ and also to a disease known in Italy as ‘‘ La Nebbia,”’ 
which is, however, caused by a different fungus. The effects of the 
disease on the fruit is that, besides being unsightly and rendered 
almost unsaleable, they soon become rotten and fall a ready prey 
to ‘‘ Blae Mould,” ete., so that all such should be rigidly excluded 
from shipments to distant markets. The fungus is found on still 
green fruit, and spreads most rapidly when the fruit ripens. 
Treatment.—The skins of diseased fruits should be burnt, in 
order to prevent the spores reaching fresh growing fruits. The 
cases containing diseased fruit should be disinfected by steaming 
or by dipping in boiling water for a few minutes. Spray the trees 
with Bordeaux Mixture as soon as the fruit sets, and again every 
few weeks up to within a month of the time of picking the fruit. 
Sooty Movuxtp or Brack Smut.—Fumagine follows the attacks 
of aphides and of scale insects, forming a sooty black membrane, 
which feeds on the sweet fluids (honeydew) secreted by these in- 
sects, and which falls on the leaves, branches, and fruits of the 
last plant they live upon. 
The growth of the trees affected is retarded in consequence of 
light and the respiration of the plant being interfered with. The 
insects further injure the plant by sucking the nutritious juices 
from the cells, and blooming and fruiting are, in consequence, 
checked or suppressed, and the market value of the fruit lowered.
