A Consideration of Adverse Temperatures 327 



g^rowth. When the blossom buds begin to open, the covering 

 should be loosened so as to admit light and air, but it should 

 not all be removed [Plate XXIII]. More of the covering 

 should be removed as the weather gets warmer, but the 

 blossoms must be exposed to the sun gradually. 



" Air and light are, of course, necessary for proper fertiliza- 

 tion of the flowers, but after this process is complete and the 

 fruit is set, all danger from the weather is considered as being 

 over. The trees are usually raised about the middle of May 

 at Canon City. 



"Raising the trees is, of course, a simple task. The 

 ground is again watered and when wet enough the trees are 

 raised. To be sure, trees that have been treated in this 

 manner will not usually stand upright unsupported. Con- 

 sequently they are propped up at an angle, usually two props 

 being required to keep the wind from swaying them. 



"This process seems to be in no way detrimental to the 

 health of the trees, since they live as long and bear as much 

 fruit according to the size of the top as those grown in peach 

 sections. It is, of course, necessary to cut out the wide- 

 spreading branches and thus reduce the size of the top in 

 order to lessen the work of covering." 



Peach trees are shown in Fig. 18 that were laid down in the 

 fall and covered with burlap and soil. Growth is just begin- 

 ning in the sp" ingand the covering is being gradually removed. 

 A tree is shown in Plate XXIII that is beginning to blos- 

 som in the spr'ng and has been partially uncovered in order 

 that the tender leaves and other parts may become gradu- 

 ally inured again to the full intensity of the sunlight 

 and air.
