While there are no very great: differences in growth of vines, 4 
those on Plat 7 are smallest, and those on Plats 3, 6,9,1land12 
are most vigorous. | ze 
August 14.— Very little difference discernible baieone pe st 
of vines on B Plats where different amounts of seed were planted. | 
Flea beetles are very numerous, and are doing much damage. eg 
F plats.— The seed from Mr. Peck has produced the most 
vigorous vines, and these show least difference now for different 
amounts of seed. Aoi 
Seed from Mr. Hood has produced least growth of vines, and 
these show most difference from different amounts of seed. ‘yo 
The Station grown seed has produced a medium growth of 
vines, and the difference in vines between two largest amounts of 
seed is trifling; the smallest amount of seed has given much less 
growth of tops so fav.. 
Vines on Plats 3 and 12, where potatoes rotted last year, are 
beginning to be attacked by rot again. Plats 5 and 6 continue 
to show darker and lighter color of foliage than any other plats. 
Destroying beetles— The Colorado beetles were plentiful long 
before the potatoes were planted, and began their work of 
destruction on the first appearance of the plants. In anticipation 
of this attack, a Kendall Paris Green Distributor of ninety-three 
gallons capacity had been purchased of the Rodbourn Manu- 
facturing Company, Breesport, N. Y. This was started June 
sixteenth, using London purple at the rate of thirteen and one- 
half ounces for each tank full of water to poison the beetles. 
Soft masses of the purple stopped the fine holes of the nozzles 
until coarser ones were tried and the distribution bettered. 
The London purple did not prove satisfactory, in that it failed 
to kill the beetles, and Paris green was substituted. Hight 
ounces of Paris green to every tank full of water cleared the vines 
of Colorado beetles, but did not affect the flea beetles which 
appeared in swarms. Twelve ounces were tried without effect 
save to injure vines wherever the machine stopped. 
Tansey tea,* kerosene emulsions, + and tobacco water t were each — 
given a trial in the strengths which have been recommended, but 
the swarms of flea beetles remained undiminished. |
