90 THE FLORIST AND 
off earlj it sometimes happens that an annual plant, such as Mignonett»3 is 
rendered biennial or perennial. The tree Mignonette is produced in this way. 
When plants are grown in a rich soil, it sometimes happens, that in place of 
producing flowers, they develope branches and leaves luxuriantly. In these 
instances cutting the roots, pruning the branches, taking a ring of bark out 
of the stem so as to retard the descent of sap, and transplanting into poor 
soil, frequently cause the plants to flower. Injuries inflicted on forest trees 
late in the season sometimes give rise to autumn flowering. When a branch is 
grafted on a vigorous stock it often happens that its flowering is accelerated. 
By this process a check is put to luxuriant branching, and the sap of the old 
stock stimulates the young graft or scion. Balfour.

the committee on Agricultural statistics of Pennsylvania, reported that the 
committee had learned since their appointment, that the State Society were 
engaged in a similar object, and in furtherance of it had already sent 
printed questions to nearly all the county societies in the State. To some 
of these, replies had been received and been printed in the volume of the 
proceedings of the State Society, published by authority of the last legisla- 
ture. It was true that no such questions had ever reached this society, nor 
was any account of the Philadelphia Society contained in the volume afore- 
said ; nevertheless, the general subject of state statistics more properly 
belonged to the State Society. That body had already commenced the
