Inoculation, Methods of Legume. By K. F. Kellerman {U.S.A. 

 Dep. Agr., Bur. PI. Ind., Circ. 63; May 1910; 3 pp.).— This deals 

 with the inoculation of new lands with the bacteria which develop 

 nodules upon the roots of leguminous plants. The advantages of the 

 use of artificial cultures lie in the greater ease of their transportation and 

 application, as well as in the absence of the danger of introducing 

 harmful weeds, which is incident to the method of transferring soil 

 from other fields upon which the particular crops in view develop 

 abundance of nodules upon their roots, though this latter practice is 

 the more certain of the two, especially in the case of alfalfa. Both 

 methods will fail if the crop which is being experimented with is not 

 adapted to the locality, or if the climatic conditions during the growing 

 season are unfavourable. In the soil transfer method it is recommended 

 to sow 200 to 300 lb. per acre on a cloudy day, or towards evening, 

 and harrow it in immediately, as bright sunshine is very harmful to the 

 bacteria. — A. P. 



Inspection in North Carolina, Nursery. By F. Sherman {Jour. 

 Econ. Entom. vol. 2, pt. 6, pp. 382-385. December 1909). — Nurseries 

 are carefully inspected and if few trees are found infested with San Jose 

 Scale these are destroyed and the nursery certified. If large numbers 

 are involved a second inspection is undertaken at the charge of the 

 nurseryman, and if this is insufficient the block is ordered to be 

 destroyed, and means are taken to see that it is destroyed. All stock 

 is required to be fumigated with hydrocyanic acid gas before being 

 ■ distributed from the nursery ; in doubtful cases this is done by the 

 inspector but usually by the nurseryman. 



The qualifications of the inspector are that he should be capable of 

 ; recognizing the important insect and fungus pests of the nursery. He 

 : should also be acquainted with nursery pra-ctices, customs, etc. 



Under the system in vogue the average condition of the nurseries 

 iis steadily improving though the scale is found in an increasing number 

 !of nurseries each year. — F. J. G.
