. Death to the rodents. Death to the Rodent*. 433. BI393 : Pocket-Gopher Mounds in Cultivator! Field. While burrowing underground, pocket gophers cut off the roots of alfaif i and other growing Crops and of orchard trees, and pile up great mounds of dirt on the surface. These mounds cover up and destroy much of the crop, damage machinery used in harvesting, and interfere with its efficient operation. destroy as many as 95 per cent of these animals through a single application of the poisoned bait. Pocket gophers occur in all States west of the Mississippi River and are par- ticularly destructive to alfalfa, grazing lands, hay meadows, and root crops. A stand of alfalfa is often entirely ruined through the cutting off of the main branches of the root sys- tem. The quantity of hay that can be harvested is reduced both by this depletion of the stand and through being buried by the great mounds of dirt which are thrown up by por kel gophers. These mounds also interfere seriously with the operation of the harvesting machinery. In addition to the direct damage caused by pocket gophers, their burrows frequently serve as an outlet for water from irrigation ditches. The flow of water through these small openings enlarges them, and breaks occur that result in serious loss of water and the flooding and destruction of crops. Such washouts also entail large expenditures in re- pairs. Burrows distributed over the irrigated areas also admit water when irrigation is in progress, frequently result- ing in the washing of deep gullies on sloping land and also interfering seriously with the proper distribution of the available water supply. A striking instance of the breaking of a canal bank, due to a pocket-gopher burrow, occurred in the Farmers' Cooperative Canal Co. project of Canyon.
