largely a matter of air drainage, and every 

 owner is urged to make a detailed study of the 

 movement of local air currents in his own dis- 

 trict. Various methods of protection are briefly 

 described, including those based on mixing the 

 air ; warming the air ; cloud or fog formation ; 

 irrigation ; spraying, and screening. A ' warm 

 water method,' adopted by Mr. E. A. Mea- 

 cham, of Riverside, Cal., by which water, after 

 being heated in a small boiler, is allowed to run 

 in furrows through the orchard, is stated to 

 have been successfully tried. The Bulletin con- 

 tains a weather map showing the pressure and 

 temperature conditions which are followed by 

 heavy or killing frosts within 12 hours in south- 

 ern California, and also gives plates illustrating 

 the different methods of protection.

 equal reputation, who have served in the 

 second class for twice, if not thrice, as long, it 

 is anticipated that this good example will soon 

 be followed. It is pleasing to find that after
