168 Seme observations on the 



one; place the sand between them and press it down with your 

 fingers pretty solid, and insert tlie cuttings close to the sides of 

 the pots, at the distance before recommended; then, instead of a 

 bell glass, place a pane of common glass over the whole, sufficient- 

 ly large to cover the large pot. If the glass does not lay close 

 to the rim of the pot, a little soft paper or cotton batting must be 

 put round the rim in such a manner as to give the pane a regular 

 bearing on every side, in order to exclude the air. If this is done 

 right, the lops of the cuttings will stand within half an inchof ihe 

 glass. The glass must be turned over every morning, in order 

 to keep the moisture, that settles on the under surface, from damp- 

 ing oft" the cuttings, and if a bell glass is used it ought to be fre- 

 quently taken off and wiped dry. 



When the cuttings are rooted they must receive the treatment 

 before stated. If the cuttings are potted and taken out of the house 

 in the summer season, a north aspect should be chosen in prefer- 

 ence to any oiher, and the pots all neatly plunged to their rims in 

 sand. •

Art. IV. Soiue observations on the general treatment of Ver-

 the Editor. 



The genus Ferbena, which, not many years since, con- 

 tained few species but httle better than mere weeds, is at the 

 present time one of the most valued in our collections. Since 

 the V. chamaedrifolia has been introduced, a new charm has been 

 given to the tribe. Several other species and varieties, very 

 beautiful, have successively been added to our gardens, and late- 

 ly the V. Tweediedna, vieing, if not surpassing, as a whole, 

 the chamajdrifolia, has been received: another, equalling either of 

 these, has just been figured in the London periodicals, called the 

 V. incisa. These three alone possess suflicient beauty, both as 

 hot-house, parlor, or garden- plants, to stamp the genus with 

 a character which shall make it known wherever there is a
