Anthracnose of the Grape. 

 Sfliacelonia ampelinum^ Sace. 

 Anthracnose or Black Spot is one of 

 the most serious diseases affecting the 

 grape in this Colony. It attacks the 

 leaves, the new growth, and the berries 

 with equal virulence. It appears in the 

 form of black spots, which are circular in 

 outline, and which increase in size until 

 they are \ to \ an inch in diameter. As 

 the spots enlarge the centres assume a 

 grey colour, and the attack upon the 

 berry is very characteristic. 



Treatment. 

 Afi'er pruning, burn all cnttingsand such 

 dead leaves as are found about. Rub off 

 the rough bark and swab at once all parts 

 of the vine thoroughly with a solution of 

 sulphate of iron and sulphuric acid. To 

 prepare this take 20 gallons of water, heat 

 it, and dissolve as much sulphate of iron 

 (green vitriol) as it will take up, then add 

 16 fluid ounces of sulphuric acid. Great 

 care must be taken in using this, as it is 

 caustic, and will destroy machinery and 

 clothes. Follow this treatment by spray- 

 ing with Bordeaux mixture once every 

 two or three weeks, commencing before 

 the vines blossom.— [Ed., Ag. Journal.'] 



HORSE WORMS. 



Sir, — Many thanks for your reply to 

 my enquiry. The worms I refer to are 

 round white worms about three inches 

 long, and seem to be in large numbers. 



Yours, etc., 



J. H. COATES.

[It should not be forgotten that in- 

 testinal parasites are generally found in 

 animals in low condition, and the best 

 manner of ridding a horse of these 

 uninvited guests is to improve and main- 

 tain in a vigorous state his general con- 

 dition. The worms described belong to 

 the Nematode class, or nnmd worms pro- 

 per, so called from the Greek word 

 meaning a thread. 



Many remedies exist which are all 

 more or less useful in either causing the 

 expulsion of thei parasites of the horse, 

 or act in establishing a condition of the 

 system which proves inimical to the pro- 

 longed stay of the worm within the body 

 of its host. 



All worm remedies proper are more 

 effective when given after a long fast. 

 Kor the present case I should suggest one 

 ounce of oil of turpentine mixed in four 

 ounces of linseed oil. Repeat this 

 medicine upon the following day, adding 

 to it 40 grains of calomel and shaking 

 thoroughly before administering. A 

 course of iron tonic medicine will enable 

 the animal to maintain its freedom from 

 these parasites. For this purpose one 

 dozen powders should be obtained, com- 

 posed as follows :— Powdered gentian, 2 

 drachms ; sulphate of iron, 2 drachms ; 

 carbonate of soda, 4 drachms. This 

 powder should be sprinkled over the 

 evening feed, and given every other 

 night in this manner until the twelve 

 powders are consumed. 



If your correspondent will report pro- 

 gress in, say, a mouth's time I will see 

 whether 1 can advise him further. 



Animals liable to intestinal parasites 

 should be able to command free access to 

 rock salt at all times.— H. W-P,] 



la the course of a lecture on " Manures, de- 

 livered by Principal Wright in the AgriculLural 

 Hall of the Glasgow Exhibition, the learned 

 Principal summed up by saying that a very 

 good manure for growing potatoes wbere no 

 farmyard manure was to be got was 6 cwt.super- 

 phosj hate, 2 cwt. sulphate of ammonia, 1 cwt. ot 

 nitrate of soda, and 2 cwt. of sulphate of potash 

 to the acre. 



There has recently been much controversy as 

 to which was the largest oak, and many claimants 

 have come forward in support of the merits of 

 their favourite tree. There is good reason to 

 believe that the " Abt;ot's Oak," standing in 

 Welbeck Park, which has a circumference ot 

 102 feet at its base, has the largest trunk. 



The loss of sheep in Queecsland has been very 

 great. The decrease in the number of sheep in 

 the Colony since last year has been nearly 

 5,000,000 



In former da} s, when the bison was plentiful 

 on the North American plains, it was common 

 for men to be left " stranded " if a herd passed 

 their cirap upward ; nothing was more terrifying 

 to a horse than his first whiff of the scent or 

 first sight of the great beast, and when thus 

 alarmed, horses broke from their pickets and 

 bolted for miles.
