Measure Seven Times!

What is a verst, a sazhen, an arshin, "seven spans on the forehead"? 

Feet, yards, inches, why do the English use different units of measurement than we do? How tall were Thumbelina and the Crooked Horse? 

The author of the book will help find answers to these questions and teach how to measure the length of objects with fingers and feet, elbows, iron boots, thrown spears, released arrows, as well as with the help of such a unique tool as "the bellow of a bull".
For younger school age.
