DEPARTMENT OF LANDS AND FORESTS FOR 1932 113 



Lecontes Sawfly. — Depredations from Leconte's Sawfly continued, but to a 

 lesser extent than formerly. Two private plantations were inspected and 

 sprayed. For the first time a very slight outbreak was noted in the nursery. 

 All jack and Scotch pine plantations were immediately given a thorough 

 inspection but, aside from the original branch attacked, no further evidences 

 of infestation were discovered. 



(c) Fungi: 



Damping-off.—A very severe attack of damping-off occurred in the red pine 

 seed beds during the warm, wet weather of June 1st, to 3rd. Severe loss was 

 experienced during the three days mentioned. No later attacks of any severity 

 occurred. Red pine was the only species which suffered unduly. 



White Pine Blister Rust- -Ribes eradication was concinued this year over 

 the area which was cleared during 1931. A close check-up showed that satis- 

 factory results were obtained from last year's work and that wild ribes are well 

 under control. Unfortunately the cultivated black currants in the village are a 

 very serious source of infection. Every black currant bush which was inspected 

 was severely infected and, unless some degree of control can be established over 

 these cultivated bushes, infection is bound to persist. 



As a result of this situation no white pine were transplanted on the nursery 

 nor were any white pine seed beds set out. 



(5) Woodlot Improvement 



In the effort to curtail expenditures very little work was done in the way 

 of woodlot improvement. The hardwood bush on the nursery was severely 

 thinnned, elm and cherry being removed and maple and basswood given 

 preferential treatment. 



On the two hundred acre block in Manvers Township, sufficient over- 

 mature, crooked and damaged hardwoods were cut to supply fuel for the nursery 

 for the next two seasons, a total of about sixty cords being cut and hauled. 



(6) Publicity 



The removal of the restriction on the number of trees made available to 

 the individual planter for reforestation purposes resulted in a very marked 

 increase in orders of from 10,000 to 100,000 trees. In almost all instances these 

 large orders were placed by previous planters. In all cases there were sufficient 

 experienced men available to ensure the proper handling of the trees. 



The Corporation of Bowmanville planted out some 25,000 trees on muni- 

 cipally owned land as a method of unemployment relief. The municipality thus 

 obtained material results from an expenditure which was a necessity in any 

 event. 



Exhibits were placed at only five fairs this year — three at school fairs and 

 two at agricultural fairs. The school fairs visited were at Welcome, Garden 

 Hill and Millbrook. Results obtained from these were not good. The agricul- 

 tural fairs visited were the combined West Durham and Clarke Township Fair 

 at Orono and Norwood Fair in Peterborough County. As products from local 

 plantations and transparencies of these plantations were main features of the 

 exhibit the results were very marked.
