CARROT FLY. 43 



given with wood-ashes in which paraffin oil had been mixed 

 in the proportion of one quart to a barrow-load of ashes 

 (about one hundredweight). When the plants were about 

 four inches high, a second dressing of the same mixture was 

 given, and a thoroughly excellent and luxuriant crop resulted. 

 It is observed that mixing the paraffin with some absorbing 

 substance is better than simply watering with it in a dilute 

 form, as it lasts longer, and is more gradually carried down 

 into the soil. — (A. A.) 



Sand saturated with paraffin oil and strewed amongst the 

 Carrots, and afterwards watered in, was noticed as a good 

 preventive. — (G. M'K.) 



At Hopetoun, N. B., the Carrot-crop was not satisfactory 

 till the use of paraffin oil (in the proportion of two wine- 

 glassfuls to a gallon of water) run along the drills after 

 thinning was tried, and proved very successful.— (D. M'L.) 



"Watering with paraffin oil in the proportion of a wine- 

 glassful to a gallon of water has been found to be of service.

It is also noted that, in an attack of the Carrot Worm near 

 Guildford, Surrey, the patches to which a dressing of paraffin 

 and soot were applied turned out well, and yielded good roots. 



The following notes refer more especially to the successful 



use of gas-lime, wood-ashes , and soap-suds, a)id also to 



successful cultivation on ground which lias a liberal su2)p>ly of rich 



manure thoroughly incorporated ivith it by the cidtivation of the 



p)revious crop : — 



It was mentioned that at Marchmont, N. B., the system 

 adopted is deep trenching after Celery, and cropping with 

 Carrots without addition of manure, and as long as this 

 practice was adhered to, the fly rarely appeared. — (P. L.) 



At Dalkeith, a dressing of gas-lime forked into the soil 

 before sowing was found to be a good remedy, as also was an 

 application of ammouiacal liquor or strong liquid manure, 

 whenever the Carrot Fly is first noticed on the wing. — (M. D.) 



At Callander, N. B., where the grub has been found 

 troublesome, the use of gas-lime was tried with success. 

 The ground was rough dug at the beginning of winter, and 

 the gas-lime was sprinkled over the ground till it was white, 

 and then pointed-in about four inches. The Carrots on 

 ground so treated escaped all attack from fly, whilst those on 

 another piece not so treated w^ere destroyed ; and a second 

 sowing made to replace these on ground dressed with gas-lime 

 also did well.— (T. B.) 



Gas-lime dug two or three inches thick into the bed before 

 sowing was found to answer at Hopetoun ; but it is observed 

 that perhaps the best and cheapest cure for the worm in
