This new system of assessment can be considered as a solution for Precision Forestry (PF) applications and can be employed as a ICT tool for the management of the forest companies. Aim of the proposed system is to manage operational information such as: a) positioning of each felling operation inside the forest, b) measurement of the time spent to carry out the felling, c) estimation of the size of every felled tree, and in the end, d) the analysis of the productivity of the felling operations. This experience is based on the operative principle which considers that the lumberjack, during the actual cutting, drives the chainsaw with the engine at the highest number of rpm. -
Felling Hazard Trees with Explosives Bob Beckley, Project Leader
United States Department of Agriculture Safety and Health Forest Service Technology & Development Program April 2008 6700 0867–2325–MTDC Felling Hazard Trees With Explosives Bob Beckley, Project Leader elling hazard trees is extremely dangerous. It can also be dangerous to leave hazard trees standing, because FFthey can fall unexpectedly. Removing hazard trees with explosives (figure 1) can be a safe alternative to cutting the trees down. Workers can be a safe distance away when the hazard tree falls. Explosives and ignition systems are safe and reliable when used properly. The Forest Service, U.S. Department of Agriculture, explosives program is one of the agency’s safest programs. Certified blasters need a “Hazard Trees” endorsement on their certification card (figure 2) to Figure 1—Fireline explosives have been wrapped around the trunk of this hazard tree. Note the catface (scar on the trunk), splits, cracks, and the fell hazard trees with explosives. separation of part of the trunk. Trees with these warning signs can be too dangerous for most sawyers to fell, but are excellent candidates for felling with explosives. -Blasting & Explosives Certificate- Agency: Issue Date: • Some trees with excessive decay or fire Name: DOB: damage are too hazardous for sawyers to License No: State: fell safely.

Andivius Hedulio Vol.II by Edward Lucas White
Andivius Hedulio Vol.II By Edward Lucas White ANDIVIUS HEDULIO VOL. II BY EDWARD LUCAS WHITE DISAPPEARANCE CHAPTER X ESCAPE At Tibur I put up at a clean little inn I had known of since boyhood, but which I had never before entered or even seen, so that I felt safe there and reasonably sure to pass as a traveller of no rank whatever. My knowledge of country ways, too, enabled me to behave like a landed proprietor of small means. After a hearty lunch I pushed boldly on up the Valerian Highway and covered the twenty-two miles between Tibur and Carseoli without visibly tiring my mount. He was no more winded nor lathered than any traveller's horse should be at the end of a day on the road. At Carseoli I again knew of a clean, quiet inn, and there I dined and slept. Thence I intended to follow the rough country roads along the Tolenus. Stream-side roads are always bad, so I allowed two days more in which to reach home, and I could hardly have done it quicker. The night after I left Carseoli I camped by a tributary of the Tolenus in a very pretty little grove. From Carseoli on the weather was fine. About the third hour of the day, on the fifth day before the Kalends of September, of a fair, bright morning, I came to my own estate. On the road nearing it I had met no one. I met no one along the woodland tracks leading into my property from that side: on my estate I met no one save just as I was about to enter my villa.
