TSUGA PATTONIANA. Of this species I have only twice in 

 the whole twenty-five years had good seed; the first time, in 1888 

 89, it germinated only 1 %; in 190910, on the other hand, in 10 

 days 53 %, in 20 days 75 /o and in 30 days 79 %. 



Thus the seed is sometimes good; but it is very difficult to 

 obtain.
