The figures given in this table show the great number of seeds 

 in pulverized sheep manure, — 4,000 to 1 pound, whieh would 

 be equivalent to 400,000 seeds in a 100-pound bag. But this 

 table re})resents only one analysis, although taken from a typi- 

 cal sample on the market. Some of the seeds named are of 

 little account, while others, like Plantago lanceolata and cer- 

 tain Panicums, often prove noxious. One lawn with which 

 we have experimented, and to which sheep manure was applied 

 freely, became badly contaminated with Plantago lanceolata, 

 which had never been noticed in the lawn before and must have 

 come in with the sheep manure. It was most abundant in the 

 poorest part of the lawn. In another case where pulverized 

 sheep manure was used plentifully a remarkable catch of a 

 beautiful little lawn grass growing about 4 inches high and 

 known as Poa annua was found. The seed of this grass cannot 

 be had in the market, and yet it is one of the most desirable 

 lawn gras.ses, thriving in the shade where other grasses will not. 

 Whether the sheep manure contained the seed, or whether it 

 merely furnished a suitable environment for its development, 

 as does potash for clover, was not learned. 



The large amount of organic matter contained in sheep 

 manure makes it an excellent lawn fertilizer, although from
