are in number two hundred and forty-two, of two square feet 

 each, inclosed by cast-iron frames. Paths of gravel two feet 

 nine inches wide separate the spaces on every side ; these are 

 surrounded by a path three feet wide, with a border for the her- 

 bage plants, such as clover, lucern, saintfoin, vetches, &c. A 

 hedge of hornbean separates the compartment from the rest 

 of the grounds, and an outside border of roses completes the 

 grass-garden. The entrance to it is a Grecian structure, de- 

 signed by J. Wyattville, Esq. ; the grass-garden was designed 

 and executed by myself, then the Duke's gardener. 



At the Nursery Gardens, New Cross, Surrey, a grass- 

 garden {Jig. 14.) has been established, for the supply of seeds 



of all the different species ; and, for exhibiting to agriculturists 



and farmers living specimens of the most useful grasses. 



In this garden, a, represents a border for the herbage plants, 

 as clover, trefoil, lucern, saintfoin, &c. ; likewise for new 

 or dubious varieties of grasses, and for experiments and 

 trials generally. 



b, A path or walk of sand or gravel, c, Paths between the 

 different grasses. d, Spaces inclosed by iron or timber 

 borders, for the perennial and known annual grasses. 



<?, Border furnished with two rows of roses ; the back row 

 consisting of moss roses, and the front row of rose unique. 



f, Leaded tubs, or tanks, for the aquatic grasses, or such species 

 as live in water. 



g, Hedge of hornbean, holly, box, or privet, to inclose the 

 grass-garden, or compartment, from the rest of the surround- 

 ing garden or grounds. 



h, Entrance to the grass-garden. 



In planting a grass-garden thus formed, it is of importance 

 to suit the different species of plants with their natural soils ; 

 this is easily effected, as the separation of the spaces allotted to 

 each by the gravel or sand paths prevents any admixture
