Theory:

Soon the roads began to get crowded. Some people were on tongas and ekkas, some in motorcars – all wearing perfume; all bursting with excitement. The children were a calm and contented lot. For village children everything in the town was wonderful. Whatever caught their eye, they stood and gaped at it with wonder. At last, the Eidgah came into view. There were row upon row of worshippers as far as the eye could see. Newcomers lined themselves behind the ones already there.
Explanation:
  
Now the roads get crowded, and there are many tongas, horse rides, some cars as well. People used perfumes and came out with enthusiasm. Children were also calm, as for the village children things in the town were amusing. They looked at each and everything with awe. Finally, they came to the Eidgah, and there were many worshipers as far as the eye could see, so a person who has recently arrived had to stand behind them.
