192 ON CONTINUOUS COEN-GROWING AT PAXTON. 



portable thrashing mill about the beginning of November. The 

 grain, as usual, was sold in Berwick market, and the straw to 

 various parties in the neighbourhood. The price received for the 

 straw was 5d. per stone of 22 lbs. 



The fields have kept wonderfully clean under the continuous 

 barley growing, but last '"year there was a quantity of annual 

 weeds, such as sow thistles, amongst the corn, which had to be 

 removed about the latter end of the summer. 



The continuous corn growing experiments on the home farm at 

 Paxton have not been carried on long enough to enable me to 

 give any decided opinion as to their probable success in the 

 future, but I am inclined to think that they will succeed fairly 

 well. My opinion at present regarding the continuous corn 

 growing system on a large scale, is that it may answer well 

 under favourable conditions, the chief of which are an early and 

 dry climate, to allow the land to be kept free of weeds, suitable 

 soil, and steam power for cultivating the land. I think, however, 

 that it might with advantage be adopted in a modified way in 

 this county, in cases where the land is too heavy for turnips. 



ON THE CAUSE OF EINGSHAKE IN TREES.

When injury, disease, or death is produced either in the animal 

 or vegetable world, it is incumbent upon all interested parties 

 diligently to inquire as to the cause, which, if once ascertained, 

 the same or some other student may find an antidote, and thus 

 produce a public good. 



Disease and permanent injury are often caused to man, 

 animals, and plants by atmospheric influences, while the want 

 of sufficient drainage, or inattention to the same, also produce 

 deleterious effects. Contact with diseased bodies in many 

 cases is highly injurious, and in some produces not only per- 

 manent injury, but death. Medical men, sanitary inspectors, 

 mining engineers, agriculturists, horticulturists, and arbori- 

 culturists have all to contend, more or less, with these in the 

 course of their professional lives. But while, in these days of 

 enterprise, research, speculation, and competition, each advances 

 in the knowledge of his own profession, we may naturally 

 expect fresh, if not grand, discoveries yet to be made ; some of
