spot {Septoria ribis) which produces 

 dead brown spots about one-eighth 

 inch in diameter (Fig. 2300), and 

 anthracnose [Gleosporium ribis) which 

 produces spots only about the size of 

 a pin head (Fig. 2299). The former 

 is the common leaf spot disease, but 

 occasionally, as 1 90 1 , we have serious 

 attacks of anthracnose. 



Hepworth, a fruit grower on the 

 Hudson, estimates his loss on 18 

 acres of currants in 1901 as 24,000 

 quarts, due to anthracnose and sub- 

 sequent sunscald, there being little 

 foliage left after July 22nd to pro- 

 tect the fruit. Sprayed bushes at 

 Geneva, on the other hand, held 

 nearly full foliage until the middle 

 of October. Fay and Victoria 

 seem peculiarly liable to the dis- 

 ease, while Prince Albert and Pres- 

 ident Wilder are almost immune. 



As a remedy we advise the use 

 of poisoned Bordeaux instead of 

 hellebore, thus destroying both worms and 

 fungi with the same application. For 

 thorough work one should give the first

spraying before the leaves appear, and the 

 second treatment when they unfold. 



The Bordeaux is made after the usual 

 formula, 4 lbs. lime, 4 lbs. of copper sul- 

 phate and 40 gallons of water ; for the 

 worms we add 3 oz. of Paris green to the 

 40 gallons of mixture.

The San Jose Scale Act was amended at the 

 last session by adding the following sub- 

 sections, — 



(i) All persons owning, leasing or man- 

 aging any orchard or collection of plants, 

 other than a nursery, shall, when any plant 

 therein becomes infested with the scale, and 

 forthwith on becoming aware, whether by 

 notice or otherwise, of such infestation, 

 destroy such plant by fire, or shall effect- 

 ually treat the scale by fumigation, or by 

 spraying with crude petroleum, kerosene or 

 soap, or by any other material prescribed 

 by the Minister. 



(2) The council of any city, town, town- 

 ship or incorporated village may, and upon
