stored in a cool place. During the winter the package containing the 

 scions was inadvertently taken out and left in the open where it was 

 fully exposed to the action of wind and frost for nearly three weeks. 

 The {package when found was returned to the store house and left 

 there until spring. On May 1 tth, 1926, the scions were unpacked and 

 grafted or budded on suitable stocks of seedling Japan walnuts. 

 Quite unexpectedly a fair percentage of scions and buds started and 

 grew well, and thus this rare varietj^ was saved from destruction. 



Equally good results were obtained in shipping waxed walnut 

 scions from Canada to England, and in transporting scion wood of 

 fruit and nut trees from Poland to Canada. These latter, by the way, 

 were cut early in the year and were carefully waxed according to the 

 writer's directions before shipment. The scions arrived in Canada 

 early in March and were held' in storage until May 21 when they were 

 grafted on native sweet chestnut stocks. Some of the chestnut scions 

 were sent on to Gellatly Bros, in British Columbia and were there 

 grafted on native sweet stocks. Observations made just recently in 

 Ontario and British Columbia show a high percentage of scions grow- 

 ing, thus affording another proof of the value of parafine wax for 

 preserving plant material. 



It may be said that scions would keep well without wax for long 

 periods of time in moist sawdust, but experience shows that this is not 

 necessarily true. The moisture content and temperature of sawdust 

 varies considerably, in some cases too much moisture is present or high 

 temperatures occur and injury to the buds takes place, while in others 

 the sawdust may become too dry and the scions suffer by dessication. 



In the tree planting experiment a number of heartnut trees were 

 dug and the roots packed in sphagnum moss. The trunks were then 

 coated with a thin film of hot parafine wax and the trees despatched 

 for planting. After being on the way for several days the trees were 

 planted and according to observations and reports have all started 

 to grow. 



Another interesting point showing the value of wax was seen on 

 some of the waxed trees. On a few of the trees a section several inches 

 long was purposely left unwaxed and on these sections the buds were
