In 1905 and 1906 there were set out on the Nursery several acres of planta- tion, the varieties being the common hardy kinds suitable for prairie growth. Measurements are taken in these plan- tations annually in order to compare the rates of growth of the different varieties, and also that we may establish the exact cost of a plantation, as this will vary according to the varieties, method of mixing, and planting distance. As soon as large enough the trees will be cut for fuel and in this way it is hoped to arrive at definite conclusions as to the most profitable varieties for a farmer to grow. The following measurements taken in these plantations last fall (1008) may be of interest as showing the compara- tive rates of growth during the early years. The measurements represent averages of hundreds of trees selected as being about average trees in the plan- tations, though we naturally find many individuals far larger than these average figures would indicate.
