EXPERIMENT STATION. 



[Jan. 



(6) Fertilizers collected and analyzed. 

 The collection comprised 981 samples representing 380 dis- 

 tinct brands. In making this collection 111 towns and 322 

 different agents were visited; 17,784 sacks were sampled, 

 representing 9,086 tons of fertilizer. Six hundred and eighteen 

 analyses have been made during the year's inspection, al- 

 though only 596 of these were published in the fertilizer 

 bulletin. The analyses not published were largely private 

 fornxulas not offered for sale and not registered, but were 

 officially collected. The registered brands analyzed are as 

 follows: —

On July 1, 1918, a new supplementary fertilizer act went 

 into effect. Its principal features are provisions for the col- 

 lection of a 6-cent tonnage fee which is supplementary to the 

 usual registration fee. It provides somewhat greater freedom 

 to the executive in prescribing and enforcing such rules and 

 regulations as may be necessary to the smooth working of the 

 act, and defines certain conditions in composition of the fer- 

 tilizer product which must be fulfilled or registration may be 

 refused. The full text of the act, as well as complete details 

 regarding the fertilizer inspection work, will be found in 

 Bulletin No. 9, Control Series, published in October, 1918. 



(c) Further Work of the Fertilizer Section. 

 Time has been found during the season, when it would not 

 interfere with the regular fertilizer inspection work, for the 

 analysis of the usual variety of fertilizing by-products forwarded
