Pollard's Improved Night-Soil Fertilizer. 



In the Station report for 1880 were given the analyses of two 

 samples of " Concentrated Privy Guano," said to be manufac- 

 tured by Pollard and Cook, of Providence. These samples were 

 brought to the Station by a party who gave his name and address 

 as F. C, Cook, 119 Ellsworth Avenue, New Haven. These sam- 

 ples had an estimated value of |129 per ton, and while flavored 

 with night soil, were essentially mixtures of chemicals too costly 

 for agricultural use. It was perfectly evident that " there was a 

 mouse in the meal," and the question at once arose whether the 

 Station should act as detective, or by giving rope possibly be- 

 come hangman. It was decided to give rope ; the analyses were 

 mailed to the address given, and as stated in the last Report were 

 made use of by Pollard in a swindling tour at the South. 



During the present year Mr. F. C. Cook called upon the writer 

 in company with several respectable citizens of New Haven, who 

 appeared as his vouchers, and- stated that he did not bring or send 

 the samples of Privy Guano, and at the time they were sent knew 

 nothing of them whatever, Mr. Cook further stated that he had 

 negotiated with H. M. Pollard, and had bought of the same the 

 right to make the " Patent Improved Night Soil Fertilizer," and 

 also stated that it was his belief that it was Pollard in person 

 who brought to the Station the samples of " Privy Guano," and 

 used without authorization, his (Mr. Cook's) name upon the Sta- 

 tion form for description of the samples. 



Mr. Cook further wished to know whether the " Improved 

 Night Soil Fertilizer," the patent right for manufacturing which 

 had become his property, was worth manufacturing. If not he 

 desired to have done with it. The patent directs to mix fresh 

 night soil with burned plaster and various other ingredients, and
