ground all the winter, and comes to active life in July or August. 

 After a time it lays eggs in the celery leaf. In September, and early 

 in October, the young grub eats and grows, and in a short time gets 

 to its full size ; it then drops from the plant into the soil, there to 

 remain in a dormant state till next summer. Grardeners from this 

 will know the exact time when to expect them, so that they may be 

 provided with plenty of dry soot to scatter over their plants of a 

 dewy morning, so that it may adhere to the under side of the 

 leaf as well as the upper side. They must bear in mind that soot 

 is not so easily washed off by rain ; if it should be, put more on. 

 "What I wish to see is, gardeners in small suburban places sow their 

 celery early in February. By so doing, the plants would be very 

 stout and fine long before the insect made its appearance ; and in 

 case of neglect in looking after the insect the plants would stand a 

 better chance. However, I have now done my best, and can only 

 add, that if this insect is not looked sharply after, celery will make 

 but a poor show on the tables of the merchant of London. I am 

 aware of the difficulty of having ground cleared for early celery ; but 

 to grow a large number of celery on a small piece of ground, I have, 

 in the large families I have lived in, always grown my celery on the 

 Scotch system — that is, a bed dug one spit or more out, and banked 

 up on either side, five feet broad ; then six inches of rich manure 

 spread on the bed, trodden hard, and dug in. Plant the rows cross- 

 ways, six or eight in a row ; then, for the next row, one foot or 

 fifteen inches from the last, and so on. The celery does not grow so 

 large as single rows, but this plan has every other advantage — 

 economy of ground, watering, moulding with a board on each side 

 of the row, winter covering, digging up in severe frost, etc. To 

 prove the great advantage of the large bed system, in 1837-8 I had 

 celery at Dyrham Park when everybody else's was destroyed. Again, 

 previous to that I had a family of seventy people to leed at Lord 

 Canterbury's, at Mistly Hall, where I grew 10,000 heads, for all 

 purposes. I look upon a large head of celery as I do long blanched 

 asparagus, long cucumbers, and the like — they go to the pigs. 



DISEASE or THE VINE A^D ITS EEMEDT. 



BY P. LAZAEIS, OF ATHENS. 



NT substance, dried and pulverized, which does not in- 

 jure the foliage or fruit of the vine, cures the disease of 

 " oidium," with which it is affected. It is because of 

 the same qualities that pulverized sulphur produces the 

 same effect, and not as a specific, as is generally believed. 

 Those who have thus far applied themselves to research, to discover 

 a remedy for the disease called " oidium," have wished to find a 

 specific, which would as surely cause it to disappear as does quinine 

 break the intermittent fever. Consequently they have considered
