the time all that he sees, stating direction and (when possible) velocity 

 of tide, movement of ice, if any ; also describe the condition of the ice, 

 whether much broken up, solid field, etc. 



Tidal Observations. Each day the time and height of high and 

 low water are to be carefully observed, and during the open season the 

 character of the tide will be carefully noted for two days before and 

 three days after the full and change of the moon. For this purpose a 

 post, marked off in feet and fractions of a foot, is to be placed in the 

 water, at low water in some sheltered spot, if any such be available, 

 and the height of the water noted every half -hour during the rise and 

 fall of one tide on each of these days the height to be noted most 

 carefully every five minutes during the hour of high water and the 

 same at low water ; the five-minute observations will also be taken for 

 one hour during the most rapid portion of the rise. Special observa- 

 tions of barometric pressure are to be taken in connection with these 

 tidal observations. 



To check the zero-mark for the tidal-observation post, select a spot 

 on shore from which the horizon line will be projected on the tidal 

 post, and record the reading of this line when seen projected on the 

 post by the observer, whose eye is to be placed at a measured height 

 above the datum-point selected on shore. 



All remarks in regard to the movements of birds, fish, etc., and also 

 as to the growth of grasses, will be carefully entered. 



As it is impossible to give to the officers in charge of stations 

 detailed instructions which would be of service in every contingency 

 which might arise, the officers are required to observe and enforce the 

 following rules : 



(a.) Every possible precaution is to be taken against fire, and, as it is 

 anticipated that the temperature can be maintained considerably above 

 the freezing-point inside the houses, two buckets full of water are 

 always to be kept ready for instant use. 



(b.) As the successful carrying out of the observations will, in 

 a great measure, depend on the health of the party, the need of 

 exercise is strongly insisted on during the winter months, and also 

 that each member of the party shall partake freely of the lime-juice 

 supplied. 



(c.) Each party is supplied with a boat, but, unless some emergency 

 requires it, it must be a rule that neither afloat nor ashore must any 

 of the party leave the station for a greater distance than they can be 

 sure of being able to return the same day. 



(d.) As soon as possible after the houses are completed and the 

 stores all in place, the party will set to work collecting sods, grass, or 

 any other non-conducting material, and before the winter sets in the 

 whole house is to be covered with this, boards overlaid, and snow 

 packed over all ; the assistance of the Eskimos should, if possible, be 

 obtained, and the whole house arched over with snow.
