early in the season, repeating twice or even three times, 

 especially if heavy showers fall after the process. () Tar 

 water, made by boiling half a pound of gas tar and two 

 gallons of water for half an hour or until it will readily 

 mix, then diluting to fifty gallons, applying as advised 

 for paraffin oil emulsion solution. 



2. (a) Dusting the plants with a mixture of lime 

 and soot, mixed together in the proportion of one 

 bushel of soot to two bushels of lime, very finely 

 powdered and broadcasted over the plants, afterwards 

 lightly hoeing in, has been efficacious in some degree. 

 () Sprinkling the young Onions with soot has been 

 adopted with some advantage, but it is necessary to 

 repeat the applications, a peck of soot being applied 

 per rod at each dressing, (c) Kainit, broadcasted on 

 land cropped with Onions, at the rate of five cwt. 

 per acre, or three and a half pounds per rod, has been 

 found of great use. It should be lightly hoed in after 

 being broadcasted on. (d) Nitrate of soda applied at 

 the rate of one and a quarter to two and a half cwt. 

 per acre, or fourteen to twenty-eight oz. per rod put 

 on infested land, after finely crushing, stimulates the 

 plants and acts badly on the maggots. 



3. Sow Parsley with the Onions thinly, the smell 

 of the former being hateful to the Onion Fly. In 

 many farms or gardens the Parsley remains after the 

 Onions, and is sometimes a very remunerative crop 

 The Onion Fly does not appear to relish umbelli- 

 ferous crops, hence follow Celery with Onions, not 

 using any manure for the latter crop.
