Book Description
This is one of the most important books in the early history of artillery. Written by Sir Ralph Payne-Gallwey in 1907, it's the first serious work on the ancient catapults to be written in modern times.In this book, Sir Ralph explores the ancient writings of sieges and their artillery. Not content to take the writings at face value, he endeavors to assign credibility to the writer, then he goes on to produce his own working versions of the ancient machines and test the principles and the claims of the ancient writers.With over 22 illustrations, the book gives details about the design, construction and operation of the three fundamental types of siege engines- the Catapult (also known as the Mangonel or Onager), the Ballista and the Trebuchet, as well as the history and effects of such weapons.

Book Description
Let children experience the learning power of play! Let’s Play is a handbook full of child-led, open-ended learning adventures. The 39 fresh, fun, and budget-friendly activities (plus more than 225 play variations) are packed with learning that helps children develop important motor, cognitive, language, and social skills. These activity starters were all tested by a slew of early childhood professionals and approved by the children they work with. Building on the early learning principles presented in the author team’s first book together, Let Them Play: An Early Learning (Un)Curriculum, they also support your transition to a play-based, child-led (un)curriculum. Jeff A. Johnson has more than twenty years of early childhood experience as a former child care center director and current family child care business owner. He is a popular keynote speaker, trainer, and author of six books. Denita Dinger has been a child care provider for more than ten years and is a frequent speaker at early childhood conferences, focusing on the topics of hands-on and play-based learning. This is her second book.
