ever, to the columns of the Leader^ published at Melbourne, Victoria. 

 A large number of localities are given in Victoria and ISew South 

 Wales near the Victoria line. From the accounts in this paper it seems 

 that the young locusts make their appearance in the last of September 

 and in October and November, become winged towards the end of March, 

 and lay their eggs in April. The habits of the species seem very similar 

 to those of the Rocky Mountain Locust ( OaZo^tewits spretus) and although 

 there is no hint of such a state of affairs in any of the articles wbicb we 

 have seen, we are of the opinion that the species has i)ermanent breeding 

 grounds from which it flies out and overruns the cultivated districts 

 further south and east, just as does spretus in this country. The same 

 general laws will, in fact, be found to govern. Only the most rudi- 

 mentary remedies are mentioned. The use of brush harrows, brush 

 and chain harrows, hot water, and spraying with kerosene emulsions 

 have been tried against the young locusts, but against the migrating 

 swarms nothing effective has been proposed. 



Later information than this just given from the Leader is given in the 

 February number of Garden and Field in an interesting article entitled 

 "Wandering Locust of South Australia; Its Breeding Places and 

 Checks," by J. G. O. Tepper. The species is there determined as Fpa- 

 cromia terininalis, and the habits given correspond with those described 

 above. It is recommended that the most strenuous efforts be made to 

 destroy the unfledged locusts during the period from August to the be- 

 ginning of October. For pasturalists, the best remedy is to ascertain 

 the extent of the breeding places and drive as large a flock of sheep as 

 can be conveniently mustered and crowded as much together as possi- 

 ble up and down the locust-infested field, taking care to cover fresh 

 ground at every passage on the same day. It is recommended that this 

 be kept up 2 or 3 days, after the locusts are permitted to re-unite. This 

 is often of some avail after the swarms become winged. Spraying 

 young swarms with kerosene is also recommended, and an additional sug- 

 gestion is made that the field be fired some distance behind the spraying 

 parties. The article concludes with a description of the method of 

 coping with locusts in Cyprus. 



We have just prepared an emergency bulletin on the subject of the 

 destruction of locusts, for use in this country, in which we have sum- 

 marized the best remedies, and shall take occasion to send a few copies 

 to some of our Australian correspondents. 



SOME OREGON "WORK AGAINST NOXIOUS INSECTS. 



Mr. F. L. Washburn read an important paper before the Oregon State 

 Horticultural Society at the annual meeting held January 13 and 14 at 

 Portland, of which we have seen the following review in the Pacific Rural 

 Press of February 7. In some successful experiments in spraying 

 with Paris green against the Codling Moth he mixed 6 pounds of soap 

 with 50 gallons of the liquid with good results, causing a thin spread-
