As postal systems developed, and the volume of mail they handled increased, many problems cropped up. To begin with, the cost of transport 
was high, and it was also difficult to calculate the exact cost of letters sent to other countries.Delivery was often slow, and this resulted in people using other means to send their messages. Many illegal postal services sprang up, causing financial losses to official postal systems. Gradually, these problems were overcome. The introduction of the postage stamp by Henry Bishop did away with uncertainties regarding that should pay the cost, and regularized charges. Since the day and month were also printed on the steps, unnecessary delays could be checked Today, we have speed post which guarantees 24 hours delivery to most places. We have come a long way indeed from the days when it sometimes took weeks for an urgent letter to reach us!
