. Analysis of test data on the performance characteristics of planning and displacement floats for supporting submerged loads. Towing; Pontoons. 29. Figure 2U - Photographs of Stabilized Vortex Rings These photographs were taken from Reference (8). observed on the floats and sphere drops. On the basis of these remarks, it appears that these striations should be existent in the fluid whether cavita- tion has begun or not. That they have not been observed at pressures above the cavitation pressure may be due to the necessity of having a "free" sur- face to provide a reflecting surface-stock-foto

Young, small saw- timber trees may qualify in every way but diameter, so the maturing proc- ess is important. Currently, 51 per- cent of the hardwood sawtimber volume is in trees over 15 inches in dbh —an improvement over 1965 when only 45 percent was over 15 inches. Perhaps more important than this increase for all hardwoods is the increase in commercially valued species.

Pennsylvania forests also ex- perienced a sizeable increase in saw- timber volume, from 31.3 to 46.4 bil- lion board feet —a 48-percent in- crease. The magnitude of the saw- timber volume increase is larger than those observed in the neighboring states, in part because Pennsylvania was logged over before those states. There are a number of factors that help explain the sizeable grow- ing-stock and proportionately larger sawtimber increase, the most impor- tant of which is that P-stock-foto
