crown had got beyond tlic dcsiructive 

 snow level. 



The crisis appeared to have been 

 passed, but nature, tliroueh its power- 

 ful agent, the north-cast wind, still dis- 

 puted the "young emigrants" their 

 right to live in their adopted land. 

 The wounds made by the wind-blown 

 branches on the bole of the trees had 

 not sufficient time to heal in our com- 

 paratively short growing season, and 

 as a result each year saw nature's tm- 

 successful atteni])t to close up the 

 wound, resulting in a series of con- 

 centric rings, each growing successive- 

 ly larger than its predecessor. From 

 a scientific point of view this was in- 

 teresting, but it did not betoken any 

 good to the young saplings, which 

 were making such a brave stand. Some 

 preventative must Ije found, and my 

 Grandfather anxiously cast about to 

 find a remedy. He saw that there was 

 only one thing to be done, and that was 

 to protect them from the ravages of 

 the wind and to carefully prune the 

 branches which had been broken. In 

 hardly less time than it takes to say it, 

 he had planted a willow hedge as a 

 wind break and had carefully gone over 

 all his trees with his pruning knife. 

 Although this was not a sovereign 

 remedy, it assisted the plantation ma- 

 terially. 



What the Results Have Been. 



On a late spring day. the same sea- 

 son when the first Black Walnuts were 

 planted, 37 years ago. it has been my 



])leasure to enter a grove of tall, clean 

 limbed trees, fragrant with the breath 

 of new green leaves. This is planta- 

 tion No. 2, the one I mentioned as hav- 

 ing been planted in an alluvial soil, and 

 (he one 1 have considered as the most 

 ; uccessful, not so much from the size 

 of the trees, for the plantation on the 

 ■.ultivated soil boasts of larger ones, 

 l)ut from the fact that it illustrates 

 more clearly and definitely the salient 

 points these experiments have to teach 

 us. 



If one looks at the i)rofits of this 

 plantation, photograph No. i, one is 

 struck with its resemblance to the side 

 of a sloping roof, the apex consisting 

 of the largest trees being under the lee 

 of a hill, and the eaves, the smaller 

 trees, growing in the open. Now, al- 

 though these trees were planted in the 

 same year, there is such a marked dif- 

 ference in growth that it will be inter- 

 esting and instructive perhaps to com- 

 pare their height and diameters. 



It will be found that the average 

 diameter of the trees in the lee of the 

 hill is 7 inches, while those in the open 

 have only a diameter of 4 inches. Tak- 

 ing the age of the plantation as ^/ 

 years, the diameter growth of the 

 former would be equal to i inch in 5 

 years. In other words, the trees in the 

 lee of the hill have grown almost twice 

 as fast as those in the open. The height 

 growth bearing very much the same 

 proportion, as Avill be seen from the 

 followine table:
