the beds slightly over with the Mixture (No, 11). 
The Onions should also be sown on such soils as 
will produce health to the plants, that there may be 
no inducement for the Fly to place her progeny 
among them. 
Mr. John Mackmurry, speaking of the 
Maggot, says, “ this animal may, in my opinion, 
be considered as a nondescript, and peculiar to 
the Onion and Shallot 5” and after detailing the 
different diseases the Onion is subject to, he pro- 
ceeds to remark, “ I have always remarked, that 
whenever the Onion becomes diseased it is liable 
to the attraction of the Maggot;” he observes, 
“ I do not think that the Maggot ever passes from 
one Onion to another, and any remedy sufficiently 
powerful to destroy the insect must inevitably 
destroy the Onion itself ; in these circumstances 
the Horticidturist perhaps does all that is in his 
power, if he be duly careful to select for his 
crops of Onions those soils and situations that 
are most likely to resist the various common in- 
cidents of season peculiar to this very variable 
climate, and containing such eligible food, imd 
in such proportion as this bulbous esculent re- 
quires.” 
Mac KRAY says, “ Salt applied as a manure 
is a good preventive of the Maggot, but it 
rarely happens that a sufficient quantity can be 
procured for that purpose,” and also he recom- 
mends as a good practice to sow Onions in ground 
that has had Strawberries four or five years.
