February, '19] BALL: ECONOMIC ENTOMOLOGY 33 



It is only when the closest cooperation and sympathy exists, that the 

 greatest good can be accomplished. A joint meeting of the two 

 societies each year, for the presidential addresses, would be a powerful 

 factor in bringing about mutual sympathy and understanding. 



Vision 



Of all the fundamentals, the power to see the possibilities and oppor- 

 tunities of the future, is probably the greatest and possibly the rarest. 

 Happily, however, a single leader may lead an army. A Moses, from 

 his cradle in the bulrushes, led a nation to emancipation; a Columbus 

 sailed on and on, towards a shore no eye had ever seen; a Foch could 

 see through the smoke of battle, to the fields of battles and victories, 

 yet to come. These, and a thousand others, have led because they 

 could see beyond the present and accomplished, because they dared 

 the unknown. Their vision and their faith were the creative powers 

 that established the modern world. 



It is America's boast, that yellow fever does not exist under the 

 Stars and Stripes; that the Bubonic plague, the triple alliance of the 

 rat, the flea and the bacillus, has been practically routed from civiliza- 

 tion; that scabies, the scourge of the western range, has practically 

 disappeared as a menace to the sheep industry; that the foot and mouth 

 disease has been banished from our soil. Newell calls attention to the 

 fact that the quarantine line of the Texas fever has steadily been 

 pushed southward, until it has touched the Gulf, and will eventually 

 disappear. These and other striking victories of scientific warfare have 

 involved problems partially entomological, but have been accom- 

 plished largely through other agencies. Newell has already called 

 attention to the eradication of the citrus canker, with its almost 

 phenomenal success. The campaign against the barberry has met 

 with a wonderful and almost unbelievable response. The spirit of 

 conquest is in the air, and if the Entomologists are to carry their 

 standard in the fore-front of this modern warfare against the enemies 

 of old, they must search the rushes for a Moses. 



Notable achievements are already to their credit. The cottony 

 cushion scale has been subjugated, the gypsy and brown-tail moth 

 compelled to intrq^ich. The waves of molesting mosquitoes have been 

 driven back and their l)ivouacs destroyed. The advanced spies of 

 devouring hordes have been stopped at our shores. The pink boll- 

 worm is now in retreat. These and other achievements have Ijeen 

 notable and worthy, but should be followed by even greater ones. 

 The cottony cushion scale should not only be subjugated, l)ut exter- 

 minated. The warble iiy passes the greater part of its life in an ex- 

 posed situation on the backs of the cattle. A concerted cfl'ort anil a
