Stem Eelworm (Tylenchus devastatrix). — " Clover sickness " and " Tulip, 

 root " in oats are caused by small nematode worms. We have not so far observed 

 these in Canada, but they have been studied in the United States and we should 

 be on our guard, Some points in the life-history of the species are given in re- 

 gard to which some common-sense remedies are suggested, such as not planting 

 a. crop liable to attack upon infested ground. It is shown that several plants are 

 injured by the worms and that they can survive the operation of digestion in 

 animals fed on infested fodder. It is the same species which causes stem-sickness 

 in clover and " tulip-root " in oats. Grain Aphis Si'pJionoiDhora granaria, Kirby. 

 Early maturing varieties of grain are recommended. The full life-history of this 

 insect is still unknown. 



Daddy Loxglegs (Tipulce). — These troublesome insects are treated at some 

 length. Amongst measures to be taken to lessen the quantity of eggs laid, are 

 mowing down coarse vegetation in places suitable for the females to lay eggs, and 

 feeding sheep on infested pastures. Draining of low land and the use of quick- 

 acting fertilisers are suggested. 



Hessian Fly (Cecidomyia destrvuctor). — This well known pest has been 

 specially studied by Miss Ormerod. The chief remedies are burning infested 

 stubble and screenings, the selection of varieties least attacked, and the use of 

 special fertilisers in the spring to strengthen injured plants. 



Wheat Midge {Cecidomyia tritici). — Deep plowing directly after harvest 

 and the destruction of screenings seem to be the best remedies. 

 - ;:;5£Thrips (Thrips cerealium), — Deep ploughing and clean farming are thought 

 to be the best remedies. 



Wireworms (larvae of the Click Beetles). — " Wireworms may perhaps be said 

 to do the greatest amount of mischief of any of our farm pests ; they destroy root 

 grain and fodder crops." So Miss Ormerod begins her article and it is almost as 

 true for some parts of Canada. Great stress is laid on the preparation of the land 

 before a crop liable to attack. Autumn feeding with sheep and the use of gas- 

 lime and salt are highly spoken of. Sir Richard Keene writes If the lea is 

 broken for oats (our general crop) it is sure to be attacked more or less by wire- 

 worms ; I top-dress with 4 cwt. agricultural salt, 2 cwt. superphosphate and 

 sometimes 1 cwt. nitrate of soda. I have never known this to fail if applied in 

 time. If the lea is broken in autumn, to have green crops in the following year, 

 I have the land worked as much as possible and apply 8 tons hot lime to the 

 statute acre ; lime as hot as possible. I always sow the seed with a liberal dress- 

 ing of farmyard dung, for such crops as mangold, turnip, cabbage, carrot, and 

 parsnip, and I use the following dressing of artificial : — 2 cwt. best bone meal, 1 

 cwt. nitrate of soda, and 3 cwt. common salt. I find the plants are soon forced 

 up beyond the reach of damage. 



Hop Aphis (Phorodon humuli). — This is another insect which sometimes 

 does enormous injury in Europe, and which has received particular attention from 

 both the authoress and Prof. Riley whose studies have supplied important links in 

 the life-chain of this insect. The remedies most to be relied on are the treatment 

 of plum trees early in the season to destroy the first brood of aphis and after- 

 wards washing or spraying the hop plants when they are found to be infested. 



Red Spider (Tetranychus telarius). — This is another of the dire enemies of 

 the hop as well as many other plants. Washes containing sulphur or kerosene 

 are suo:s:ested. 



^Iangold or Beet Fly {Anthomyia hetce). — The remedy most spoken of is 

 high cultivation ; but the benefits of a kerosene emulsion are suggested by the 

 •experience of one of the correspondents quoted.
