Prevention and Eemkpiks.—In gardens where maggot- attack is noticeable in tho podn, the Pea-haulm shoii'd be cleared away directly tlio crop is gathered, so that all .-^tray podp (which are very likely to be infested) may be cleared off the ground before the maggot can go down "into it. This haulm should bo carefully destroyed at once; the safest way is to burn it, and it would be a very good plan to lay the haulm and any other combustible rubbish at hand along the rows where the infested Peas stood, and burn it there, so as U get ril at once of all grubs remaining in the pods or quite near the surface of the ground. For field treatment, as the haulm could not well bo spared, it would be desirable, if a Pea-growing district was infested, to plough deeply, so as to bury the chrysalids well down during the winter; or to skim the surface lightly, so as to throw them open to attack of birds. But commonly the regular rotation of crops might be expected to prevent this infestation getting ahead. ° In garden treatment it might be worth while to watch whether the little grey moth infested the Pea-plants during flowering time, especially in the evening, and in case they were noticeable in any great numbers it might make a difference in the amount of egg-laying to dust the plants with any powder dressing as soot, &c., which might be obnoxious to the moLhs, but would not do harm to the leafage or blossoms.
