Shade Influence in a Plantation of Three-year White Pine Trans-

These figures show plainly the benefit of some shade for white 

 pine the first year after planting- In this dry year, 43 out of 

 every 100 trees without any shade died, while even the moderate 

 shelter furnished by low brush, such as sweet fern, cut this loss 

 more than half. Or again, the trees without shade were only 

 about one- fourth (26.9%) of the total number, but furnished 

 over one-half (52-5%) of the losses. With some shade the per- 

 centage of survival does not fall below 81, and averages 85.5. 

 With no shade, the percentage is 56.5- 



The number of trees in the lower half of Table i are insufficient 

 to justify conclusions as to the most favorable degree of shade, 

 although the falling values at the bottom of the column "Per cent 

 Alive" are at least suggestive. The table does indicate that, 

 within limits, the greater the amount of shade, the better the 

 chances for success ; and, what is of especial interest if true, that 

 a protection of low shrubbery is of substantially equal benefit to 

 one of short open-grown trees which may later cause great
