"Last year this experiment resulted very ftivorably to the sliallow 

 culture theory; this year less so, and yet decisively, considering the 

 extra cost of deep culture. In other words, so far as this experiment 

 goes it proves that deep culture is not beneticial." 



Test of varieties of cotton (pi>. 140-151). — Tabulated notes are given 

 for 17 varieties of cotton. 



Cotton at iliffcrcnt distances (pp. 151-155). — Cotton was planted on 

 1 acre of land in rows 4 feet wide and afterwards thinned to distances 

 of 1, 2, 3, and 4 feet, respectively, in the rows. The entire acre was 

 uianured with 312 pounds of superi)hospliiite, 78 pounds of muriate of 

 potash, and 130 jtounds of nitrate of soda, at a cost of $0.00. The yields 

 of cotton at different distances are tabulated. The author's conclusions 

 are as follows : 



(1) On land capablo of making between 1 and 1.5 balesof cotton per acretbe plants 

 sbonld not be closer tban 4 by 2 feet, nor wider pr<)l>ab]y than 4 by 3 feet. 



(2) The greater tlie distance given the more important it is to secni'e an early 

 stand, tliiii out early, and give rapid cultivation. 



(3) Close planting gives a larger yield in the early fall, or at the first and second 

 pickings. (The 4 by 1 series in the experiment was 161 pounds ahead of the 4 by 2 

 series at the close of the fourth picking, October 16.) This is because each plaut, 

 when planted close, will make nearly if not quite as many blooms in the first few weeks 

 of blooming as each plant in widely planted rows. Between the date of the first 

 and second pickings, a. period of 12 days, 1 pound of cotton was yielded by every 

 15 plants of the 4 by 1 series, while in the 4 by 2 series 12 plants were required to 

 1 pound. When it is considered that there were only 5,005 plants to the acre in the 

 4 by 2 series against 9,250 plants in the 4 by 1 series, the explanation of the greater 

 yield of the 4 by 1 series at the second picking is plain. At the fifth picking, Novem- 

 ber 4, 43 plants in the 4 by 1 series yielded 1 pound, while in the 4 by 2 seies 13 

 plants only yielded 1 pound. 



Effect of (liff^erent amounts of fertilizers applied to cotton (p]>. 155- 

 157). — An acre of land containino' 52 rows of cotton was used for this 

 trial. A mixture of GO pounds superphosphate, 15 i)ounds muriate of 

 potash, and 25 pounds nitrate of soda per acre was applied to different 

 series of rows in this amount and in two, three, four, five, and six times 

 this amount, respectively. The yields of the series of rows receiving- 

 different amounts of fci'tilizers are tabulated. " Successively increasing- 

 amounts of fertilizers do not result in the same ratio of increasing- yields 

 of cotton. It follows that the larger the amount of fertilizers the greater 

 will be the resulting cost of the increase per i)ound, while at the same 

 time there will be left in the soil a correspondingly larger amount of 

 fertilizer for the use of the succeeding crop."

Irish potatoes (pp. 1C5-174). — The experiments were in continuation 

 of those reported in liulletin Xo. 8 of the station (see P]xperiment Station
