White stag. A white stag (or white hind for the female) is a white-colored red deer, explained by a condition known as leucism that causes its hair and skin to lose its natural colour. The white deer has played a prominent role in many cultures' mythology.
The average commercial dump truck can haul anywhere from 10 to 14 cubic yards of dirt. The actual price of the dirt can vary depending on the type. Now, a truckload of dirt is a lot of dirt, so you would only need that much dirt for certain projects.
When you purchased the wheelbarrow, it should tell the volume in cubic feet. For example, Home Depot sells a 6 cubic feet wheelbarrow. Of course, you won't fill it all the way with gravel because it will be too heavy. For example, 6 ft^3/27 = 0.222 yds^3 * 1.4 = 0.311 tons, or roughly 600 pounds of 2B stone (gravel).
