    <p style="hp">The coal mini screen shows the coal reserves beneath your city. The coal seams are shown as red and green on a grey background. You will have to build a coal mine close to one of these seams to extract its coal.</p>
	<p style="hp">The first time you ask for this information, you will have to undertake a coal survey which will cost you one million currency units. After that the information is free to look at again.</p>
    <p style="hp">Left click on the mini screen to reposition the main window. Toggle overlay mode by pressing 'v' or clicking on the large overlay button.</p>
