REPORT OF THE DIRECTOR. —  
AAA ‘ T l ° .
The year, though begun under the most auspicious conditions, _ · L i I 
gl) was marked by a serious disaster to the Station by the partial . ·` _?  
_ destruction of the Station building on the night of February ;“·    
m' 22d. The loss was a severe one to the Station, not only in the p_ . V -Z se 
and destruction of the building, but also by the loss of valuable   — .  
lm records, and especially the laboratory records, by which much ` lp  
that p of the work already done in many lines will be a total loss. A T  
I as Fortunately the records in the ofiice were saved. A great part     .,~—¥$;i·
L.- *1
H to of the time of the Station force has necessarily been taken up     g  
nts, in preparing temporary quarters and planning for future quar- V   ~ .  
ave ters. No time has been lost in rebuilding on the same model as ~   _ j  
before, and we are now situated once again as fortunately as we , `  
were before the fire, but unfortunately without any of our rec· . ``4   .
