ed by actual experiments can be of no prac- 

 tical value ; but a few general remarks upon 

 spore-formation and its application to this 

 disease will be of interest. Bacillus inilii be- 

 longs to a form known a.s endosporous — spores 



formed within the bacillus or germ. Bacillus 

 thoracis belongs to the so-called aHhrosporous 

 form, in which the spore separates itself from 

 the rod or germ by fission or transverse sec- 

 tion, and does not form within as in Bacillus

THK CELEBRATED ALFALFA PLANT AND ROOT. 



The plant represented in this plate grew in a rich, loose soil, with a heavy clay .subsoil and an abundant 

 supply of water, the water level ranging from 4 to 8 feet from the surface at different seasons of the year. 

 The diameter of the top was IS inches, and the number of stems 360. The plate shows how these crowns gather 

 soil around them, for the length of the underground stems is seen to be several inches, and this represents the 

 accumulation of nearly this much material about it. 



This is one of the largest plants that I have yet found. The specimen, as photographed, was dug April 

 30th, 1896.— /?r. Headden, in Bulletin No. 3s, "Alfalfa:' See Editorials.
