Su(di a method might i>rove more effective where the humus is not so abundant in the soil. Experiments with tobacco ])roducts show that they are ])robably the best material for the control of the green- house millepede. Tobacco Dust. Tobacco dust s[)rinkled ou the beds at the rate of ."iOU pounds to the acre, or about one ounce tcj each nine square fe(d, ju'o\ed f.'iiriy efVi'ctive. On the day following suidi a treatment .about idghty- live per cent of the milleitedes on the beds were dead, although some appar- ently noiinal indi\ iilu.'ils were moving ai'fiund through the dust. Of the mille- pedes btdow the surface, only about live ]ier cent were dead. Specimens were as numerous on the treated bench as on the check ]dot. Two days later no mille- jpe found on the surface, and the nundier in the soil was about half of th(! number found in the check plots. No more dust was a])plied and in a week conditions on the treated ]dot were again normal. On another pbd a secoioi dosage w;is given thret; days after the tirst, with the result that at the end of the week only about live per cent of the former nundur remained. In a third experiirunt the tobacco ilust ^vas worked into the soil instead of being mercdy spiinkled on the surface, 'i'lie following morni
