worm, ciiiTant borer, flea beetle, pea weevil, strawberry crown-borer, 

 cut-worm, and grain beetle {/SUvanus snrhiamen.sis). There is also a 

 preliminary account of experiments at the station with various insecti- 

 cides for the grain beetle. Gum camphor, kerosene, kerosene vapor, 

 the fumes and a liquid preparation of bisulphide of carbon, and the 

 vapor of crude carbolic acid were (he principal remedies tested. Bisul- 

 phide of carbon proved the most effective, but there are difficulties in 

 the wa3^ of its use in granaries. The experiments will be continued. 



Gophers and rabbits, F. L. Washburn, B. A. (pp. 24-29, illus- 

 trated). — Brief notes on the pocket and gray gopher and thejack rabbit, 

 with suggestions as to means for their repression. 



Analysis of bone meal, P. H. Irish, Ph. D., and W. D. Bigelow, 

 B. A. (pp. 30, 31). — Tabulated notes on chemical and mechanical analy- 

 ses of two samples of bone meal. 



The need of a fertilizer inspection in this State is urged, and the con- 

 ditions are stated under which the station will examine samples of com- 

 mercial fertilizers sent to it for that purpose.

Experiments in growing potatoes, C. S. Plumb, B. S. — The 

 experiments with potatoes at this station in 1889 are discussed in this 

 bulletin under the following heads: (a) Concerning the influence of the 

 amount of seed tuber planted upon the resulting crop of Irish potatoes ; 

 (b) trial of the Rural IN'ew Yorker trench system of potato culture; (c) 

 tests of varieties of Irish potatoes ; {d) early vs. late culture for sweet- 

 potatoes. The soil used in all the experiments was a clay loam with a 

 heavy clay subsoil. 



TnfJuence of the amount of seed tuber planted upon the resulting crop. — 

 Under this head three different experiments with Early Eose potatoes 

 are described. 



1. Comparison of lohole tubers of different iceights for seed. — Eight 

 different lots of whole tubers of Early Kose potatoes were seL cted ; each 

 lot, with one exception, consisting of 100 tubers. Each potato of each lot 

 was weighed on a Fairbanks silk scale, and each lot was planted in a row 

 by itself, the rows being 3i feet apart and the tubers 2 feet apart in the 

 row, with the exception of one row, in which they were 3 feet apart. A 

 table gives for each row the weight and number of tubers planted, the 

 date of vegetation, blooming, and ripening, numberof tubers vegetated, 

 and the height of plants June 20. From the data reported it appears 

 that: (1) The largest tubers bloomed first and produced the highest 

 (and also largest) growth of plants ; (2) the smallest tubers bloomed 

 last and produced the lowest (and smallest) plants, and ripened one day 

 earlier than the largest; (3) large size apparently favored earliness of 

 bloom, height, and size of plant, and, to a certain extent, delayed 

 ripening; (4) ])lants from tubers weighing from 4 to 8 ounces ripened 

 earlier than those from tubers of greater or lesser weights.
