. I FERTILIZERS
1 ` BY H. E. Cuivris
  The following is a brief report of the work of the Fertilizer
{ Departnient for the year 1916.
i   There were registered during the year 764 brands of fer-
0 tilizer, by forty-five firms doing business in this State. These
 _ brands included complete fertilizers, nitrogenous superphos— i
A  phates, bones, acid phosphates, acid phosphate and potash salts,
 [ and nitrate of soda. The number of brands of complete fertilizer
  was about 20% less than the previous year. On the contrary,
  · the nitrogenous superphosphates increased about ive times, the
 i number of acid phosphate and potash mixtures was about 20%
 3 of the previous year, while no potash salts whatever were reg-
,  istered.
 { During the year our inspectors collected samples at various
 ‘ places in the State and samples were sent in by farmers, in ad-
  dition to the samples sent by manufacturers when registering
  their fertilizers, as required by law. The analyses of these vari-
  ous samples are published in Bulletin 205.
 — We issued during the year 1916, 128,040 stamps of 100-
  pound denomination, 850,072 stamps of 125—pound denomina-
  tion, 7,596 stamps of 167-pound denomination, 6,230 stamps of
 E 200 pound denomination, and 3,746,000 tags. The total value of
 ;’ the stamps was $30,393.75, representing 60,787% tons of fer-
 ; tilizer.
 I By comparing the business of 1916 with that of the previ-
  ous two years we find a reduction of about $12,000.00, or 30 per
 M cent., in the receipts. The receipts during the years 1915 and
 S N14 were each nearly $43,000,00, This heavy falling off was
.1  universal thruout the United States. In many states it amounted
  to as much as 50 per cent.
