does not act as it should, because it is washed away by showers of 
rain, or because the temperature is too low for a sufficient emission 
of sulphurous acid gas. In such cases try liver of sulphur. Do 
not increase the dose, as liver of sulphur is corrosive, and soft soap 
may impart a nasty taste to the grapes. 
Crown Gat of the grape (called “‘ Broussin ’’ in France) shows 
like large cancerous growths at the crown of the vine. A knock with 
the hoe or the plough, the bite of insects, sunscald, or a variety of 
causes will produce these unsizhtly growths. The treatment should 
be somewhat similar to that of cancer of the apple. 
Vines planted on land highly manured with stock manure are 
more liable to show these growths which are caused by a bacterial 
organism that attack a wide range of hosts. 
Remove the growth, trim the wound, and wash the wound with 
an antiseptic wash, or paint it with some agjd solution such as recom- 
mended for Black Spot on grapes. Knives or secatures must be 
washed in an antiseptic after using. 
Seurrt Berry (Phoma tuberculata, McAlp.).—This disease is 
at times troublesome, especially amongst the Muscats. The fruit. is 
the part attacked ; it is at first ashy grey or slaty blue in colour, 
dotted and speckled with numerous small pustules, for a long time 
covered by the outer 
skin or epidermis, When 
gently pressed between 
the fin:er and thumb 
the berry squirts out its 
contents. Towards the 
end of the season the 
berries dry partially, but 
are always pliable. 
No experiments re- 
lating to preventive 
means have been tried.
