This is the third installment of the Martin McMillan mystery/adventures for middle grade readers (ages 9-13). A vacation to Scotland finds thirteen-year-old skateboarders Martin McMillan and his friend Isabel drawn into another exciting mystery. Gaelic verses, recently found in the lining of an old trunk, hold the key to Druid secrets on the windswept Isle of Lewis. Clues lead to the ancient Calanais Standing Stones, which rival the wonder of Stonehenge. Martin and Isabel are determined to uncover the truth before other, less scrupulous parties can beat them to it. But dark forces go to great...

The term "Chiefs of Arms" refers to the Chief of Field Artillery, the Chief of Coast Artillery, the Chief of Cavalry, and the Chief of Infantry. The Artillery Corps contains two branches: the Coastal Artillery and the Field Artillery. This inventory descr

A fire characteristics chart is a graph that presents primary related fire behavior characteristics-rate of spread, flame length, fireline intensity, and heat per unit area. It helps communicate and interpret modeled or observed fire behavior. The Fire Characteristics Chart computer program plots either observed fire behavior or values that have been calculated by another computer program such as the BehavePlus fire modeling system. Program operation is described in this report, and its flexibility in format, color, and labeling is demonstrated for use in a variety of reports. A chart...

Rothermel's surface fire spread model was developed to use a value for the wind speed that affects surface fire, called midflame wind speed. Models have been developed to adjust 20-ft wind speed to midflame wind speed for sheltered and unsheltered surface fuel. In this report, Wind Adjustment Factor (WAF) model equations are given, and the BehavePlus fire modeling system is used to demonstrate WAF calculation and effect on modeled fire behavior. There are differences in implementation of the same basic wind adjustment models in various fire behavior applications, including the Fireline...
