 contains general statements reiL;ar(ling the condition and needs <>!' lliis 

 industry iu the United States, a liistorical resume of'ostreacultural exper- 

 iments and methods, and a brief account of experiments by the autlior 

 in the culture of oysters in a chdrc at Key Port, Xew Jersey, and in the 

 station laboratory. Most of the work of the year was i)reparatory and 

 actual experinu^ntinji' was not begun until hite iu the season. The lab- 

 oratory experinuMit was uuiterially interfered with by the impurity of 

 the water used and the improper construction of the tanks. Tlie autlior 

 records a discovery that spernnitozoa may survive the death of the 

 oyster at least 5 days. 



Eepokt of IJotanist, F,. I). Halsted, 1). So. (pp. L'LM-L*3!>).— Tliis 

 is for the tirst 10 months during which the statiou has had the services 

 of a botanist. A considerable portion of this time was necessarily 

 occn}»ied in prei»arat(>ry work. The r(>i)oit includes notes on weeds along 

 the same lines as those treated in bulletin No. 5:^ of the station (see 

 Experiment Station Kecord, ^'ol. i, p. b>()); explauations regarding the 

 ])olleii of plants, with a brief account of observations by a number of 

 ])ersons in New Jersey, witli reference to the relation between wet 

 weather at the time of the blooming and the setting and maturing of 

 fruit. An outline of the ])lan of these experiments was given in Special 

 Bulletin of the statiou (see Experiment Station liecord, vol. i, p. 134). 

 The season of 1S89 was very wet and thus unfavorable for such experi- 

 ments. In the case of apples it was observed that no fruit was set when 

 the flowers were not permitted to get dry. Keeping strawberry vines 

 wet during the time when the fruit is setting is probably undesirable. 



Some exijeriments were made in clipping the lower half of currant 

 clusters. This practice increased the number, size, and M^eight of the 

 berries as compared with those on untreated bushes. There are also 

 brief notes on potato rot [Vhytophtliora infestans), grape rot, cranberry 

 gall fungus {Synchytriuni vaccinii), cranberry scald, cucumber mildew 

 {'Pcronospora rnhcnsis), sweet potato rots {Rhizopus nif/ricans, Ceratoeys- 

 tisjimbridta) leaf blight on lilac {Fhyllosticta halstedii), and fungicides. 

 Oljservations on the two iliseases of the cranberry above referred to 

 were reported in Bulletin No. Gl of the station (see Experiment Station 

 Eecord, vol. i, p. UG3). The cucund)er mildew was first observed on 

 cucumbers growing under glass, and was afterwards found on pumpkins, 

 squashes, and field encumbers in various parts of the State. 



Report of Entomologist, J. B. Smith (pp. 241-313, figs. 22). — 

 The author assumed the duties of entomologist to the station April 

 1, 1889. Considerable preliminary work was necessary in securing 

 apparatus and making collections of insects. General information 

 regarding this department was given in Bulletin No. 55 of tlie station 

 (see Experiment Station Eecord, vol. i, p. 134). The report contains an 

 account of the horn flj^ {Hannatohia serrata), taken from Bulletin No. 62 of
