The destruction of otir early fruit trees, excepting a few to be loft as traps, has 

 been suggested. This method is based upon the erroieous belief tliat Trupcta works 

 only in early fruits. If wo raised no early fruit the early flies would do no harm. 

 The destruction of the larvie from thcfee trap trees would not lessen the ravages of 

 the later-appearing races of flics upon late fruits. Destroying the early fruit would 

 force many of the early-appearing fli(!8 to find a nidus for their eggs in the later fruit, 

 thus increasing the number of later flies. 



The destruction of the windfalls and the burninf? of refuse from 

 bins and barrels are urged as the most effective means of repressing 

 the maggots. 



Insecticides {\)\). 21:2-254, illustrated). — Directions for the use of insec- 

 ticides are given and various forms of spraying apparatus are described 

 and illustrated. 



List of fruits growing at the station (pp. 255, 25G). — This ijicludes 33 

 varieties of apples, 13 of plums, 1 of pears, 4 of cherries, 14 of grapes, 2 

 of currants, 1 of gooseberries, 4 of blackberries, 8 of raspberries, and 17 

 of strawberries. 



llEPORT OF VETERINARIAN, F. L. RUSSELL, V. S. (pp. 257-266).— This 

 contains accounts of hog cholera and parturient apoplexy in cows, with 

 special reference to the symptoms of these diseases and their treat- 

 ment. 



Report of meteorologist, M. C. Fernald, Ph. D. (pp. 267-281). — 

 " For 20 years meteorological observations have been taken at the Maine 

 State College, and summaries of the same have been ])ublished yearly 

 in the college reports. These summaries relate to the larger part of the 

 phenomena regarded as meteorological. 



"It is not the purpose of the station to duplicate this work of the col- 

 lege, but rather to make a somewhat careful study of certain meteoro- 

 logical conditions, an acquaintance with which can not fail to be of 

 value to those engaged in practical agriculture." 



Tabulated summaries are given of observations with the hygrometer 

 in a forest and in an open field, with soil therniometers at depths of from 

 1 to 36 inches, with terrestrial and solar radiation thermometers, and of 

 the velocity of the wind and the amount of rain-fall. Detailed records 

 of similar observations are also given for the month of June, 1889. 



Co-efficients of digestibility for protein, W. H. Jordan, 

 M. S., AND L. H. Merrill, B. S. (pp. 282-285).— This is a comparison 

 of the co-efficients of digestibility of protein as obtained (1) with animals 

 in the ordiimry manner; (2) by making an allowance in these tests for 

 the fiEcal nitrogen soluble in ether, alcohol, hot water, and lime water, 

 and (3) by pepsin-pancreas digestion on numerous feeding stufts. The 

 results by the second method averaged 11 per cent higher than by the 

 first. The results by the second method agree very closely with those 

 obtained by artificial digestion. 



Loss of food and mantirial value in selling sweet-corn, J. 

 M. Bartlett, M. S. (pp. 286, 287).— Tabulated data are given for four 

 lots of corn, showing the relation of i^arts of the plant and their composi-
