Further exi»eriiuents conducted in 1007 with remedies for the cabbage nia;^- 

 p>t arc reported. The best results were olitaiiicd by treating caulitlovver with 

 a dtH'oction of white hellebore prepared by slcei)ing 2 oz. of the powder for 

 an liour in 1 qt. of water and then diluting with water to make 1 gal. This 

 was ajiplied with a watering jtot (from which the rose had been removed) a 

 few days after the plants were set out, with a second ai»plication 5 days later, 

 followed by a third 5 days after the second. Holland cabbage appears to be 

 exempt from attack but red cabbage is not. Cabbage maggots were found to 

 emerge from pupte which were buried 5 in. deep in the soil. PseudoeucoUa 

 yiUvttci was the most common parasite that emerged from the puparia, other 

 parasites, including Uomotrupus hicapillaris albopictas, Aphwrcta pcgomyicr, 

 and Mcgaspiltifi siriatipes. 



From the results obtained with the worlc with the post during IIJUS and jtre- 

 \ ious years it is concluded that "radishes grown iu the open ai'e apparently 

 benefited by several api»lications of hellebore decoction (4 oz. of white hellebore 

 steeped in 2 gal. of water) applied with a watering pot, first when plants 

 are 1.5 in. high, and 3 or 4 later applications at 5 days' intervals; or by the 

 use of tobacco dust with equal frequency in the same way." 



Spraying experiments for jtests of the orchard and garden are reported and 

 discussed. " Spraying jihun trees with arsenate of lead and Bordeaux mixture 

 (3:4:50) two or three times at beginning of curculio season, at intervals 

 of a week or ten days will prevent at least 50 per cent loss of fruit from 

 curculio injury, to which must be added whatever injury from fungi is saved 

 by the use of Bordeaux mixture." 



Attention is called to the occurrence of crown gall on raspberries and that 

 such comes under the Minnesota law relating to contagious diseases of plants. 

 The irritating harvest mite or jigger Is described and preventive remedies sug- 

 gested. White grubs { Lachnosterna rugonn and L. fiisca) are said to have 

 been more destructive to lawns in the State in 1908 than ever before. The bee 

 moth (Gallcria mrlloiicHn) is now under investigation. Foul brood is described 

 and remedies briefly considered. 



Reports of orchard inspectors (Zoo/. Bui. Pcnn. Dipt. Agr., 6 (WOS), Xos. 8,

 work. 



A European ant (Myrniica levinodis) introduced into Massachusetts, W. M. 

 Wheeler (Jour. Econ. Ent., 1 {190H), A"o. 6, pp. 337-339). — The author reports 

 the discovery of M. levinodis at Forest Hills and Jamaica Plain, Mass. This 

 species and the A'ariety previously described as hrursi with Tctramorium 

 (CNpituin are the only species known to have been introduced into this country 

 fronj Europe. As .1/. Icrinodi.s is very fond of attending aphids and prefers to 

 nest in cultivated soil, it is suggested that it may become of economic 

 importance.
