THE COLOXY PLAN. 25 



ing the remaining ten months. The operation of the 

 mower and other haying machinery will not be seriously 

 interfered with in this plan, which is peculiarly adapted 

 to the extensive alfalfa fields of the Great Plains region. 

 If a location is preferred in a field of wheat, rye, barley, 

 oats or millet, the birds may be turned loose after har- 

 vest and before the weeds have grown tall enough to 

 encourage the fowls to steal their nests, while the scat- 

 tered kernels gleaned in the stubble will be quite an 

 item. Alfalfa, however, is destined to become one of 

 the most important crops, which will occupy millions of 

 acres of the great trans-Missouri region and feed count- 

 less numbers of horses, cattle, sheep and swine, and as 

 grasshoppers breed in this crop in myriads, the tunnel 

 plan is particularly suited to the alfalfa belt. 



The sixty acres of grain, which, as previously stated, are 

 raised every year on our colony poultry farm, may have 

 some of these poultry-runway movable-grasshopper traps 

 located thereon. K partly grown fowls, not yet of a 

 laying age, or chicks just separated from their mother, 

 are placed in such runways, among growing crops, a 

 very good house to be attached to the runways is shown 

 in Fig. 2. It may be built four feet high from floor to 

 peak of roof and four by twelve feet on the floor. Mov- 

 able perches rest in slots cut in the tops of blocks eight 

 inches high. The ends of the building and the two 

 doors are alike, the latter being fastened down nights by 

 a padlock. Several barbed fence wires are stretched on 

 both sides of the building, to admit air and keep out 

 thieves. Moving is done by attaching a team to a chain 

 fastened to one of the end crosspieces on which the 

 floor rests.
