An esteemed correspondent says: 'I would ask what you meant by 'Blue Grass' in the last number? Poa compressa is the 'Blue Grass' of all the Eastern country, and merits the name, having a blue color, but the P. pratensis is the Blue Grass of the West and is much better for a lawn, though the name 'blue' is a poor one for the brightest green".

[Poa compressa is the 'Blue Grass' of botanists. There is no doubt of this, and yet we are nearly sure that if any one send to a seed store in any part of the United States for 'Blue Grass' he will get Poa pratensis. We are as sorry as our correspondent that it is so, but so it is. - Ed. G. M].
