The issue of new gunpowder cartridges for the Enfield rifle in February 1857.
It failed because either the change did not work well in many business settings, or it was inefficient (due to the inefficiency of the conveyer-belt system). A more accurate reason is that the circuits couldn't handle the traffic during peak hour. The customer's orders were regularly mixed up. The conveyer-belt system was not fast enough or efficient enough to handle it.
I believe its the <span>consist mountains thick with trees, rivers and poor rocky soil that was difficult to farm and unsuitable for crops.
I hope this helps :)
