Making Club-Fertilizers. — In some towns farmers club together 

 and piircliase their separate ingredients, each one doing his own 

 mixing liimself. In other cases the club decides upon a definite 

 formula and sends out specifications to manufacturers for furnishing 

 the same already mixed and sacked, letting the contract to the lowest 

 responsible bidder. One of the most successful instances of this sort 

 is the Riverhead Town Agricultural Society of Long Island. They 

 have found that a fertilizer containing 4 per cent, of nitrogen, 8 per 

 cent, of available phosphoric acid and 10 per cent, of actual potash 

 is well adapted to their conditions for growing potatoes. They 

 require the nitrogen to be distributed in three different forms, one- 

 Iia If being fish-scrap; one-fourth, nitrate of soda; and one-fourth, 

 sulphate of ammonia. The potash must be in form of muriate. 

 For the season of 1895 they were able to get 1,200 tons of this mix- 

 ture made at $29.32 a ton. Commercial fertilizers of similar com- 

 position sold for $36 to $40 at the same time. The actual saving 

 affected by the members of this club amounts to not less than $10,000 

 a year. 



Where to Purchase Unmixed Materials. — Any large manufac- 

 turer of fertilizers will generally fill orders for separate ingredients. 

 Farmers are advised to write to three or four different firms and get 

 their prices. In comparing price, one should take into consideration 

 the question of freight. The schedule of prices given later may be 

 used as a general guide in regard to what one should pay for different 

 forms of materials. 



Farmers will find their chief difiiculty in knowing in what forms 

 and quantities to order separate fertilizer constituents. 



The suggestions found in the preceding pages giving this infor- 

 mation in regard to our more common crops will be found helpful. 



Below is given a list of manufacturers who are willing to sell un- 

 mixed goods direct to farmers. A few firms indicate their prefer- 

 ence of selling through local agents where these are already estab- 

 lished.
