THE NOETH DAKOTA FARMSTEAD 59 



The Box Elder Plant Louse, Elm Leaf Louse, Snow Ball Louse, 

 Scurfy Scale, attacking Cottonwoods and Willows and the Cottony 

 Maple Scale, attacking Box Eders, Maples, Virginia Creepers, Bass 

 Woods, and frequently Elms, are the most serious sucking insects. 



There are certain gall making insects and twig borers that cannot 

 be controlled except by removing the galls or dead twigs, which gen- 

 erally contain eggs or young larvae. 



(Residents of North Dakota desiring assistance in the planning of 

 farm ground plantings and further suggestions as to planting mater- 

 ials, can secure such assistance by sending a sketch, drawn to scale 

 of the farmstead to be planted, together with a statement as to the 

 location, kind of soil, slope of land or any other information necessary 

 in drawing up a suggestive plan, to the North Dakota Experiment 

 Station, Agricultural College, N. D. 



All such requests will be given as much attention as the work 

 of the department permits.)
