At Least 150 pears, a soil which will furnish suflacient nutriment to the tree for two or three generations. It suggests the importance, also, of sufficient moisture, for soil depth is of little value unless the sub-soil or under stratum contains sufficient water to hold plant food in solution. Many or- chards are being planted in places where they will grow fruit successfully for 20, 25 or 30 years, but not for a longer period, because a few feet below the surface there is a stratum of rock or of hardpan, or perhaps there is not sufficient seepage to moisten the soil a very great depth and the food substances in the soil are not available. Especially is this so in the arid and semi-arid regions where it is necessary to resort to irrigation to grow fruit successfully. Then, too, in these irrigated sections there are many places where there is sub-irrigation and the soil is wet to a very great depth. This may be considered desirable if there is not too much water to injure the tender roots of the trees. In West Virginia I have observed that in every case where the orchards were from 50 to 75 years old they have been situated where the soil was deep and where there was seepage enough to supply the root system with more mois- ture than generally falls on the surface; that when the orchards were planted on situations where there was no seepage, and where the rock came near the sur- face, the orchards were dead. In 1905 I visited a number of farms where 40 years before there were flourishing orchards, yet. Please note that these images are extracted from scanned page images that may
