How did the two urchins track Griffin’s footmarks and gave him a tough time?

Crowds were a big threat to Griffin. He could be wedged in them and to be discovered in no time. Accidental collisions made matters worse. His feet were trodden by people; hence he was obliged to keep away from crowds. When the Salvation Army March attracted a huge crowd, Griffin thought it safer to run up the while steps of a house and stand there till the road was cleared. Unfortunately for Griffin, two urchins not only joined him on the steps, but they also noticed the footmarks that his muddy feet had made on the whitened steps. They saw the marks going up there was no trace of their returning. Then, to their great surprise they detected the outline of feet sketched in splashes of mud. This ‘ghost of a foot” soon generated interest and attracted other passerby as well. Griffin was left with no choice but to swing himself into the portico of the next house. One of the boys still kept track of these feet. Now many eyes turned towards the ‘Running feet’. By this time Griffin’s feet had become hot and dry, and at the first opportunity, he rubbed his feet with his hands. Griffin went away leaving behind his drying footprints and wondering people.
