This grass, which wag brought to our attention by Col. Hillyard, of Mississippi, as one of the most valuable of all introductions for that State, is also attracting much attention in Australia, as we find by the following notice from Dr. W. R. Guilfoyle in his annual report of the Melbourne Botanical Garden:

"The Doub Grass {Cynodon dactylon), often erroneously called 'Doob,' is a native of Bermuda, and in my opinion ranks next to Buffalo Grass (Stenotaphrum glabrnm) as a hardy pasture grass for arid climes, though as a lawn grass it is inferior, presenting in the winter a brown and rusty appearance. I can state from experience, however, in New South Wales and Queensland, that where it has been introduced round a station hut horses and cattle, when left to feed as they chose, have collected round it eagerly, refusing the native grasses in luxuriant growth near them, so long as a blade of Doub grass remained. As to the nutriment contained in these two grasses there can be no doubt, as many squatters across the Murray could testify. Respecting their durability the same may be said, as during seasons of excessive drought, when scarcely a blade of them could be seen, so tenacious of life were they, that when the weather broke they sprang up in rich luxuriance, and when native grasses were totally destroyed by the drought these two species were the only ones that withstood it."
