 USEFUL TABLES. 



The following tables have been compiled from every source that is con- 

 sidered reliable. They are largely the result of Station investigations in 

 this country and in Europe, and are given here as a means for reference, so 

 that the reader can find for himself facts that otherwise he would have to 

 correspond with his Station to find out. 



AVERAGE FERTILIZER CONSTITUENTS OF SEA WEED. 



One hundred pounds of dried sea weed of various kinds has been found 

 to contain of: Nitrogen, 2.65 pounds; phosphoric acid, 0.75 pounds; potash, 

 3.35 pounds; lime, 9.00 pounds; magnesia, 1.68 pounds. It is evident 

 therefore, that the estimate which the farmers near the sea have placed on 

 this material as a manure is warranted by its composition. Those situated 

 accessible to the great deposits that are washed upon our beaches will be wise 

 to save all they economically can. We were once in our life a seaside 

 farmer, and know full well the value of the material. We found that the 

 best use for the sea weed was to put it in the cemented basement we had 

 under the cow stables, and as the droppings were sent down through shutes 

 they were mixed and piled with the sea weed. The great abundance of 

 moisture and salt contained in the material prevented injurious heating, and 

 a regular daily dressing of the piles with phosphate, added not only to its 

 manurial value the phosphoric acid in which it was deficient, but also acted 

 as a further preventive of the escape of ammonia, and the resulting manure 

 gave remarkable results on our truck crops. As a manure for sweet potatoes 

 we found that raw weed, spread thickly on the land during the winter and 

 plowed under in the spring, was all that was needed to give the most abun- 

 dant crops. 



CONSTITUENTS OF FORAGE PLANTS PER ACRE. 



The Pennsylvania Station made experiments to determine the total dry 

 matter and plant food in certain forage crops, and gives the following results:
