used as dwarfing stocks in a breeding program with timber-type chestnuts and 

 directly as fruit trees for small gardens. Seedlings of native chestnut, represent- 

 ing progenies of trees free from blight under conditions of severe infection, were 

 obtained from a nursery in British Columbia. Seeds of several strains of dwarf 

 chestnut were also obtained for further testing and breeding work at the Southern 

 Research Station. 



REFORESTATION 



Nursery Stock Inventory 

 In co-operation with the Statistics Section of the Division, Research Re- 

 port No. 33 entitled "Inventory of Nursery Stock", was prepared to present our 

 findings and recommendations on this problem. This report was distributed to 

 all foresters in the Department, to the nurseries, to universities, other research 

 stations, outside nurseries, etc. , because of the information contained in the 

 general field of sampling techniques. It is believed now that our nurseries have 

 sufficient technical guidance to be able to prepare inventories within the accuracies 

 required. 



Nursery Stock Packaging 

 In the spring of 1955, an experiment was conducted at the Kemptville 

 Nursery and at Larose Forest to study the moisture retaining material in bales of 

 nursery stock. A report of the experiment was prepared and published as Research 

 Report No. 34. The report showed that poplar excelsior was as effective as 

 sphagnum moss (and about half the price) in retaining the viability of stock stored 

 in bales for periods up to four weeks. 



Straw Fumigation Experiment 

 In the fall of 1954, an experiment was established at the Orono Nursery 

 to study the effectiveness of steam and MC2 treatments of straw used as seed bed 

 mulch, in killing weed and grain seeds. Counts were made in 1955 of the numbers
