Can you have 2 scouts on 2 different squares and come time to gather resources can you gather from both squares? A friend of mine was the english and had 4 armies on 4 different sqaures and also 2 scouts on 2 different squares and thought he could harvest 6 production from his city and 6 production from his 4 armies and 2 scouts. I did not see in the rules where only 1 scout gathering is aloud.

You most certainly can. This is why getting all your scouts out on the board early is key to getting those few extra production hammers and/or trade arrows and/or special resources you need. Just one extra trade can save you a whole turn on research by being the difference between having just enough trade for a tech or being one short.

Don't remember if it's in the rules but we always play 1 scout (army for English) per city

Wow, that makes the British pretty powerful. thanks for answering my question
