Queen's Co.— The disease has appeared in a garden at Abbeyleix. The 

 owner of the garden has supplied me with the following particulars : " The 

 disease was first noticed in 1902, and was very bad then. Almost all the 

 bushes have been attacked, ' Whinham's Industry ' very badly ; ' Heart of 

 Oak ' and Berry's ' Early Kent ' rather badly ; 1 Pitmaston Greengage ' 

 and ' Early Sulphur/ however, remained nearly free. Many of the old 

 bushes (some probably ' Red Lancashire ') and the large smooth-berried 

 kind kept quite free. One border of 1 Whinham's Industry' dressed in 

 the spring with about three parts of superphosphate to one of kainit 

 remained almost free from mildew and caterpillar ; another border of the 

 same variety of Gooseberry dressed with three parts of kainit to one of 

 superphosphate was very badly attacked, and these bushes are, in fact, 

 quite ruined with mildew and caterpillar. The berries were attacked first ; 

 the tops of the shoots are now (July 14) showing the white dust badly. 

 The garden is on light sandy soil, on a deep bed of limestone gravel, and 

 is perfectly flat and walled in." 



Co. Dublin. — The disease has been noticed in a garden at Foxrock. 

 The following particulars have been sent to me : " The fungus was first 

 observed in May 1908. The number of bushes attacked was half-a-dozen ; 

 these I have treated with sulphide of potassium, and burned all the berries. 

 The disease appears now to be checked. It first appeared on the berries. 

 As far as I know, the varieties attacked are all kitchen varieties, chiefly 

 1 Large Amber.' The bushes are, I should say, eight or nine years old, 

 and were all purchased about five years ago from a florist at Newtownards, 

 Co. Down. I should tell you that for the past three years I have had 

 a great deal of trouble with my gooseberry-bushes owing to caterpillars, 

 which have eaten off the leaves." This correspondent, writing later (July 

 14), reported : " I am glad to say that there are no fresh cases of the 

 mildew showing in my garden. Some eight or ten bushes became ulti- 

 mately affected, and nearly all the berries and leaves on these were taken 

 off and burned, and the bushes syringed with sulphide of potassium 

 according to your directions. A few berries on adjacent trees were 

 affected ; these were taken off and burned, and for the last fortnight I 

 have seen no sign of the disease. The crop is a very heavy one, and will 

 be ripe in another week or ten days." 



Co. Down. — An extensive outbreak of the disease has occurred at 

 Newtownards. The owner of one garden reported (on June 17) as follows : 

 " I have been making a careful inspection of a plot of 250 trees, and can- 

 not find a single tree free from the disease. It was first noticed in 1900. 

 The greater portion of my bushes are 1 Amber,' 1 Warrington,' and 1 Green 

 Gascoigne,' but I cannot say one variety is more severely attacked than 

 another. There has been a little of it observed on the ripe fruit for the 

 last three years, a sort of brown sticky substance being left, making the 

 fruit unmarketable. I have also been examining a quantity of young 

 trees (' Amber ') which I intended to use in replanting the ground occupied 

 by the present lot (after taking off the clean fruit and burning the rest), 

 but I find now the fungus on the young shoots of these, as enclosed." 



In the specimens sent, the uppermost leaves of the branches and the 

 apex of the young shoots were covered with a white powdery mass of 

 conidia, while the lower part of the young stems bore a skin of matted
