The character ot the soil has a great deal to do with the frequency of irriga- tion. Soils that are deep and homogen- eous have obviously a large storage ca- pacity and hence can hold much water in the subsoil reserve. During the drouth of this summer everybody must have noticed that on such soils crops do not suffer so quickly for lack of water. With shallow soils the condition is differ- ent. As the storage capacity is limited the irrigation must be more frequent. Any one who is observant and who studies his soil and notes the behavior of the crops should in the course of a few years learn to know how to irrigate so as to secure good yields. What constitutes proper irrigation is a matter of much importance. It does not consist of a complete saturation of the ground or putting as much into it as it will hold for no crop will thrive with its roots in watterlogged soil. Under average conditions long continued irriga- tion and the use of large amounts of water are uncalled for. A sufficient irri- gation should carry water to every part of the soil where there is a lack of it and it should replenish the reserve supply in the subsoil. Anything more than this is a waste and usually an injury. The mistake of applying too little is rarely made but that of too much is not infre- quent. Porous soils soou take up all that is re- quired and any excess goes into the un- der-drainage and is lost. On soils that absorb water very slowly the irrigation must be continued longer than required to run the water over the ground. Where there is no under-drainage and where the soil is shallow over-irrigation will set up excessive surface evaporation which may result in accumulation of al- kali in injurious quantities. Where fur- rows are used it is not always necessary that the irrigation shall be continued un- til percolation has proceeded in
