LITTLE TRANSPLANTING IS DONE In the State forest tree nurseries of Pennsylvania, the aim is to produce large quantities of trees that are large and strong enough for forest planting purposes. In most commercial nurseries, on the other hand, the aim is to produce relatively larger-sized trees to be 22 used for ornament or shade. To produce such trees, transplanting one or more times is necessary. Trees suitable for reforestation purposes can be grown without transplanting. Thus, it is possible to avoid the expenditure of time and money that is required in the production of transplants. During the early years of Pennsylvania forestry, con- siderable transplanting was done at Mont Alto. During the first year of the Mont Alto Nursery, 10,000 one-year-old white pine trees were bought from a commercial nursery and transplanted in the local nursery. In 1910 fully 500,000 trees were transplanted. But the loss llirough winter heaving was so heavy that the added expense of trans- planting was not justified. At the present time, the practice in the Mont Alto Nursery is to trans- plant only a few trees of standard stock which are to be grown for orna- mental plantings, as well as exotics and other special trees that are to be kept for several years. This transplanting work is usually done in the s])ring. When such work is done in the fall, it should be coiiij)lrted be- fore September 15. This permits good root growth before freezing weather arrives. Exi)erience has shown that spruce trees may be transplanted at any time up to the first day of December. Whe
