make the best showing in the tests
 being made at Martinville under the
 supervision of County Agent T. M. I Williams, according to the statement
 es were inspected on September 3.
 The poorest showing was made by No. IA, which was given treatment of POO pounds of nitrate of soda, 800 pounds of acid phosphate and 800 pounds of potash. This patch had a
 boil count of 290 and an estimated yield of 249 pounds The cost of the fertilizer treatment was $22.75, and the value of the yield is estimated at $24.90 giving promise of profit of $2.15 per acre.
 MT. Williams detailed statement shows that acid phosphate, 250 pounds to the acre; potash, 40 pounds to the acre; manure, 10 tons to the acre, and lime, 10 tons to the acre, promise to be the most profitable fertilizers used on the 16 experiment patches. Of the check patches, which were given no treatment, Mo- 9 is high with an esti- mated net value of $31 per acre. The estimates made from the boil count on September are next to the | final statement upon the experiments. When the cotton has been gathered and weighed, the full record will be published, and the relative showing of all the patches listed. As planned by MT. Williams, the teams which pre- pared the charts at the public inspec- tion will keep them and make the production is published. Each chart will then become an accurate record of the first fertilizer tests on Faulk- ner soil
 Mr. Williams made the statement lupon the manner of checking the re- suits and lessons to be gaine dfrom the showing made by the different fer l tilizers:
 | "The committees or teams making
 the boil count of the various fertilizer plots at the Martinville field meet Sep tember 8, counted only those bolls
 from quail egg size and up, believing these to be safe from shedding and
 and early frost. In arriving at the es- ltimated yield, it was figured that for leach boil per running foot there was I2l4 pounds seed cotton per acre, this
 being the rule for three foot six inch
 rows and Rowden cotton. This would vary of course with different varie- ties.
 1.-Two hundred and fifty feet was counted in each plot and an average number of bolls per foot figured from this. Total number of bolls in the 25O feet an estimate is given without giv- ing number of bolls per foot, as this will be easy for you to do, if you SO desire.
 "The seed cotton, for convenience, was figured to be worth 10 cents per pound. The cost of the fertilizer is subtracted from total value of cotton. No charges were made as to cost of distributing fertilizer.
 "To summarize it appears that plots three, four, five, nine and sixteen are the outstanding ones. Taking into consideration the cost of hauling the lime in plot 16 and the manure in plot five, Nos. three and four are the leaders.
 1t will be noticed that plot nine is check, but in adding all check plots, which would be a fair way, as none have fertilizer, we get an aver age of $24.12 against $35.53 and $32.70 of plots three and four But on the other hand the variation of plots hav- ing no fertilizer might lead us to think that the same conditions might prevail in the fertilized plots.
 ''In a field of cotton srort dis tance from these plots, Mir. Arm strong used about 200 pounds of H. 20 fertilizer. Near the middle of the field a row was left without fertilizer. The rows near this one have more than twice the number of bolls per foot than the unfertilized row. Which further adds to the statement that without an actual test of fertilizer on your farm you will not be able to tell the kind needed. Also conclusions drawn from test covering a period of years are much more reliable than conclusions arrived at from one or two years test
 Save this article and compare with final yield. As all plots are to te weightde separately and reported on later"
 In detail, the check showed the fol- lowing results by patches:
 Plat No. 1.-Check patch, no fer tilizer used and no expense incurred; boil count 327; estimated yield per acre PTS pounds; value S27.
 Plat No. 2.-Fertilizer treatment, nitrate of soda 100 pounds; cost $5; i hOll coup+ 2G7. aStip,atad viald nor
