 vestigations, Agronomic Investigations, Horticultural Investigations,

 gations, and Experimental Gardens and Grounds — were discontinued, 

 and all the scientific and technical publications prepared in these 

 offices and in those subsequently organized have been issued in a single 

 series of bulletins. '

 technical publications of the United States Department of Agricul- 

 ture are not for general distribution. All copies not required for 

 official use are by law turned over to the Superintendent of Docu- 

 ments, who is empowered to sell them at cost." All applications 

 for these bulletins should therefore be made to the Superintendent

 accompanied by either a postal money order, an express money 

 order, a draft on New York, or by cash. Postage stamps, foreign 

 money, uncertified checks, and defaced or slick coin will not be 

 accepted in payment for publications. No charge is made for post- 

 age on documents forwarded to points in the United States, Guam, 

 Hawaii, Philippine Islands, Porto Rico, or to Canada, Cuba, or 

 Mexico. To other countries the regular rate of postage is charged, 

 and remittances must cover such postage.
