It is proposed to foutimie the investigations during tlie next and future seasons. 

 Tlie main mixture experimented witli was tbe carbolic emulsion. Tliis mixture is 

 made by dissolving 2 lb. of soft soap in 2 gallons of warm water, to wliieh is added 

 2 pints of crude carbolic acid. This stock solution is then diluted 1-20 and applied 

 at the rate of 5 oz. to each cabbage. 



It was figured that 10 cents' worth of the diluted mixture would treat 100 

 plants once at this rate, not including the cost of labour. It was necessar.v to 

 treat each cabbage seven times between the end of May and the middle of July : 

 consequently the cost per 100 plants was approximately 70 cents, exclusive of 

 labour. 



The past summer's work indicated that the above mixture applied seven times 

 only held a balance in favour of treatment of 33 per cent, covering a great many 

 varieties of cabbages. There is undoubtedly much variation in tbe degree of resis- 

 tanc.y between the various varieties of cabbage; consequently it is not fair to judge 

 the 33 per cent, with too great a degree of detail. It is merely wished to point out 

 that the carbolic emulsion, which is the most recommended mixture for control, has 

 not offered perfect results from treatment. 



A greater benefit than maturity was noticed under the above treatments in 

 the individual comparative weights of the cabbages harvested. Without going into 

 details again with the various varieties, it was found that, covering the whole 

 experiment, a net increase of approximately 2 lb. per individual cabbage was figured 

 in favour of the treated cabbages over those left untreated. Quicker maturity of 

 the treated plants also resulted. 



The diluted mixtures did not harm any cabbage, not even those in the seed- 

 bed, when treated while growing. Dipped plants at tran.splanting were apparently 

 checked somewhat, but in the main survived. The eggs were not affected by treat- 

 ment by either carbolic or kerosene emulsions. 



In a large turnip-field experiment performed at Agassiz two significant points 

 appear to have been demonstrated: (1.) The net results in weights of turnips 

 harvested on equal proportions of an acre from roots treated with solutions of kero- 

 sene and carbolic emulsions over untreated roots do not warrant the time, labour, 

 or expense of liquid treatment of the roots. (2.) That thinly seeded rows possess 

 more eggs and maggots per root than thickly seeded rows, and that the process of 

 "thinning" the roots in the row again al^ects the infestation per individual. Conse- 

 quently, from the past summer's experience, it would seem advisable to seed heavily — 

 roughly, sixty to eighty plants to the lineal foot — and follow this by "thinning" in 

 the month of June. 



Experiments performed by others in tbe past have indicated that good success 

 may follow the use of thin felt-paper tarred disks iilaced around the neck of cabbages 

 and cauliflowers flush to the ground; that radishes may be screened against the fl.v; 

 that the old cabbage-stalks and refuse left around the field had best be destroyed 

 as soon as the crop is harvested; and that rotation of land be practised as far as 

 possible. 



The Imported Cabbage-worm (Pontia rupa:, Sch.). 



According to the late Dr. Fletcher in his Annual Rejwrt of 1001-1902, this insect 

 was first recorded at Kaslo in 1S99. It proved very troublesome in I'JOl, having 

 spread over the entire Province. During tbe summer of 1900 it reached Vancouver 

 Island. This insect of recent years, though present, has not attracted very much 

 attention from gardeners and farmers. The white butterflies are noticed early in 

 the spring and are known to all. The caterpillars feed on a number of plants of 

 the cruciferous family. They are green in colour and over 1 inch in length wheu 

 fully mature. 



Ar.sonate of lead applied before the cabbages " bead out " will bo found the best 

 remedy.
