the food manufactured and stored becomes available and is 

 used after the first rains have made it possible for growth to 

 be renewed. If, as was the case last winter, there is much 

 mild damp weather, growth will be luxuriant, the stored food 

 will be freely used, the conditions for sucker-formation and 

 for fasciation will coincide. In the spring, especially after 

 a mild winter, during which much growth and comparatively 

 little food manufacture have taken place, the stores of food 

 having been considerably reduced, growth will be less luxu- 

 riant and food manufacture will become more necessary and 

 more active. We see, then, some reasons for the formation 

 of the fasciations and for the time of their appearance. 



B. Albinism. 



The most remarkable and, I am surprised to find, not an 

 especially rare peculiarity of the suckers or sprouts which 

 come up from the stumps or from the old roots of felled or 

 fallen redwood trees, is that they are sometimes perfectly 

 white. My attention was first attracted to this peculiarity 

 when, in the fall of 1898, a student brought some redwood 

 twigs bearing white leaves into the Botanical Laboratory of 

 this University. On inquiry I learned where these white 

 redwoods were growing, and in the fall of 1899 I went to 

 the spot. These are the only white redwoods which I have 

 seen growing, but I have heard of others much larger and 

 one which must be several years old was brought to the 

 laboratory from the "Redwood Retreat," about twelve 

 miles from Gilroy. This last I planted in my garden, but it 

 lived only a short time, whether because it was injured^ in 

 the transplanting or because it could not bear transplanting 

 late in the spring I do not know. Its behavior before it died 

 I will speak of presently (p. 95). 



The white redwoods which I have visited are on the sum- 

 mit not far from the stage road between La Honda and 

 Redwood City, and on the line to the left of the road (as 

 one goes toward La Honda), where the forest gives place 

 to open fields. The tallest redwood tree in view marks the 

 spot where the white ones grow. This tall tree is one of a
