Economic importance of vegetable food. The destruction of 

 sprouting grain means a loss of dollars and cents to the rancher. 

 This loss is minimized somewhat by the limited time during 

 which injury is possible and the possibility of protective measures. 

 A much smaller loss can be attributed to the destruction of grain 

 picked up in newly sown fields. Grain on or near the surface 

 of the ground in seeded fields is of doubtful value, as it cannot 

 be depended upon to furnish a strong, healthy plant. Much of 

 the wild oats and some of the tame oats must be considered waste 

 grain or uncultivated grain. Its destruction, in spite of its 

 utility as feed, cannot be considered a direct loss in money value. 



Practically all the other seeds destroyed are the seeds of weed 

 pests. The destruction of the seeds of certain forage plants such 

 as filaree could be considered a detriment if they were destroyed 

 in large enough quantities to make any difference in the amount 

 of forage available. This same plant is considered a weed in 

 many places. Any destruction of the seeds of thistles, sunflowers, 

 Johnson grass and like weeds must be considered a benefit. 



ANIMAL FOOD 

 Coleoptera (Beetles) 



The most constant article of diet of the meadowlark consists 

 of beetles. The habitat of the bird would forecast this fact. 

 Ground-beetles (Carabidae, Tenebrionidae) , click-beetles (Elate-
