be rolled occasionally to flatten the Immps which form and 

 it should be kept mowed. The most serious objection to 

 Bermuda grass is that it will not remain green during freez- 

 ing weather. Frost kills the stems that are above ground, 

 hence the Bermuda grass lawn is always brown or yellow as 

 long as there is frost at night. It should always be irrigated 

 with clear water. 



Buffalo Grass (Bulbilis dactyloides). Much has 

 been said of the value of this grass, probably more than 

 is warranted by the facts. It occurs in the eastern tier of 

 counties in this State forming irregular patches often several 

 square yards in extent. It forms a thick sod and inclines to 

 spread, but it is very small and produces but a small amount 

 of forage in that region. It is probably palatable to stock 

 and quite nutritious as well, but in New Mexico it can in no 

 way compare in importance with the Grama and Galleta 

 grasses (with which it is most frequently associated) even 

 assuming that it is of equally good quality, since there is 

 nothing like the quantity of it. This condition in New Mex- 

 ico has caused the author to wonder if the Blue or White 

 Grama was really the grass the buffaloes lived upon and the 

 name Buffalo Grass had been applied to another grass acci- 

 dentally or for a different reason than the obvious one. Its 

 habit of spreading by means of rvmners makes it very resistant 

 to trampling and also to drought, and once established it 

 seems able to hold its own with the Grama, which is able to 

 crowd out most other plants. 



The Grama Grasses (Bouteloua spp. and Atheropo- 

 gon spp.).* These are without question by far the most 

 important range plants in the arid Western grazing lands. In 

 New Mexico there are ten species often referred to the single
