sometimes long clistanees awny and for a time feed on tlie foliage of the pea- 

 I»Iants. As soon as the young imds are formed, the females lay their eggs 

 on them. The beetles all become fully developed at the same time, which is 

 about the middle of August, and all. whether they winter outside the pease 

 or inside the grain die about the same time the fullowiug season, viz.: during 

 the month of June. 



Loss by soiriiiy ^yc(:■^^illrll I'rtisc. — That seed pease wliirh have been liored 

 b.v weevils are very seriously injured. I have proved by actual experiments. 

 ■\Veevilled small i)ease gave only from 13 to 20 per cent, of plants which bore 

 pods, and these were all weaker than plants frcnu perfect seed. Large pease 

 gave a better percentage of from 10 to 28 per cent. Therefore, weevilled 

 pease should not be used for seed if any other stock is obtainable. If. however, 

 this is impossible, much more seed should be sown to t!ie acre. 



Remedies. 



Fiimi(/ntioii. — Fumigation with bisulphide of r.-irlion is a sure remed.v. 

 jTor the treatment of small quantities of seed, iiarticidarly b.v farmers, an 

 ordinary coal oil barrel is very convenient. Tliis will Imld about five bushels, 

 or 300 pounds of seed, and may be treated with .'! <iun<es of bisulphide of 

 carbon which ma.v be poured right on to the pease. Care nuist be taken to 

 close up the top tightl.v. This is best done with a c.-iii made s|iecial]y for the 

 puriiose. but ma.v also be done with fine sacks daniiiened and laid smoothly 

 on the top, over which boards are laid, with a considerable weight on them 

 to hold the covering down closely. The bisulphide of carbon should be of the 

 best quality, which will vapurise without an.v residue, and the exposure 

 should be for 48 hours. Pease should be fumigated as soon as possible after 

 harvest, but they may be treated at any time when the tenqierature is above 

 freezing. As the vapour of bisulphide of carbon is very intlanniiable. this 

 work should be done at a distance from other buildings and no light of any 

 kind must be brought near. Xo smolving must be allowed near the buildings 

 where the bisulphide of carbon is being used. When large (immtities of 

 pease are to be treated at once, in specially prepared houses, one pound of 

 bisulphide of carbon to every 100 bushels of seed, is the amount regularly 

 used b.T large seed houses, as in these tightl.v constructed "bug houses" 

 there is less waste of the vapour during the necessar.v expo.sure of 48 hour.s. 



HoWintj orev seal. — Where onl.v a few seed pease are used, a most reliable 

 remedy is the holding over of seed until the second .\-ear. Tease should 

 always be bagged up and the sacks tied at once after threshing. The weevils 

 are not able to eat their way througli the bags, even when these are made of 

 paper. All the weevils which emerge, either in autunni or the following 

 sunmior. will iierish inside the bags, and the seed can be sown the following 

 .year without danger; the sound seed will not be injured b.v being held over. 

 Seeds showing the hole from which \\ee\"ils have emerged should be sorted 

 out before sowing. 



Trcuilng iritli coal oil. — A remedy which has l)een useil li.v many farmers 

 with satisfaction, is to drench tlie seed about two weeks before sowing with 

 coal oil. using about half a gallon to a barrel, or five bnsliels of seed. 

 Immediatel.v after putting on the oil, the jiease should be shovelled over and
