Principles of Plant Culture. 



and the earth should be moderately packed about the 

 roots with the feet, or otherwise. 



If the soil is dry, it is probably better to moisten it be- 

 fore placing it about the roots, rather than after, since 

 we have then a better opportunity 

 to judge of the quantity of water 

 required, and the soil is less likely 

 to settle away from the roots. 



Trees of considerable size should 

 generally be staked or otherwise 

 supported after planting, to pre- 

 vent shaking by wind (Fig. 138). 

 Surrounding the trunk with poor- 

 conducting material, such as hay, 

 straw or canvas, tends to prevent 

 damage from sun-scald (185), to 

 which recently-transplanted 

 trees are especially lia- 

 ble ; since the evaporation 

 stream (77) is much re- 

 duced, the bark tends to 

 become unduly heated. 



411. Devices for Transplanting. With young trees 

 and plants, that possess abundant vigor, rapidity of 

 planting is often of greater importance than the ob- 

 servance of precise rules. In this case, that method is 

 best which secures a given number of transplanted and 

 vigorously-growing plants at the least cost. The trans- 

 planting devices shown in Figs. 139-141 aid greatly in 

 accomplishing this end.
