Standard, from •which to procure good sorts of Fruit Trees to 

 plant on the Road Sides. 



24. Meeting of the Society of June 11. 1824. 

 Robin /a Pseud-Acacia is recommended to be planted on 

 poor sandy soil, where no other tree will prosper ; also for 

 its very durable wood, which, in France and on the Rhine, 

 is preferred to any other for stakes. 



25. Observations on the Slope of the Hoofs of Hot-houses. 

 By Professor Link. 



M. Link says that the direction in which the rays of the 

 sun fall upon the roofs of hot-houses is of less consequence 

 than is generally supposed, provided the plants have as much 

 light as possible, particularly from above. 



26. Germination of the Seeds of Tectona, grandis. 

 Dr. Kielmayer, from Wiirtemberg, who has sent seeds of 

 Tectona grandis (teak-wood) to the Society, gave the follow- 

 ing account of the method used at Stuttgardt to make the 

 seeds germinate. The external covering, as well as the nut, 

 must be carefully opened, and the small seeds which are con- 

 tained in the four cells of the nut taken out, and sown in 

 pots, which are then placed in the bark bed, when the seeds 

 will come up very soon. 



30. Descriptions of Two Sorts of Melons. By M. Seitz.

31. On the Arrangement of a Public Garden for the Town of Mag- 

 deburg. By M. Lenne. 



M. Lenne presented to the Society plans and descriptions 

 of this garden, which was begun under his direction : — 1 . A 

 finished vertical profile serving to show the ultimate effect. 

 2. A descriptive explanation of this profile. 3. A correspond- 

 ing outline, or working plan for planting the trees. 4. Level- 

 ling plan of the ground (Nivellemento Profile). 5. A list of 

 trees and shrubs, with numbers agreeing with those in the 

 outline, to show the different kinds with which the groups and 

 masses are planted. 



The trees in the profile [fig. 40.) are beautifully disposed, 

 and the bare inspection of the engraving is full of instruction 

 to the young landscape-gardener. We recommend him to 

 study every part of it with great care, and more particularly 

 the disposition of the masses relatively to the roads and 

 walks, and of the scattered trees and small groups relatively
