"It seems, then, that a man must be pretty well versed in the weather to be able to read the signs."
"That is a correct observation. The instrument in the hands of one who has had experience with its use is absolutely necessary; it is not a very satisfying device for those who do not take the time or trouble to read all the signs, and note all the indications."
As detailed in a preceding chapter, the hardened steel rod for the compass was brought out for the purpose of securing it in a little case, so that it might be utilized to give them the true north.
It was a difficult task to find a means of suspending it, for the reason that they had no tools which would make fine and carefully pivoted balances, but eventually this was done, and they were gratified to see the little rod or bar swing around and point north and south.
The work of arranging suitable closets for the various provisions and providing a miniature kitchen was the next thing in order. This occupied several days. Instead of taking the bedding in their house, it was decided that new mattresses should be made up from the barley, of which there was quite a quantity on hand.
One of the receptacles taken from the cave was a copper jar, which held five gallons of water. A top was made for this which could be sealed up, to hold a reserve supply of water. In addition two other vessels were also provided for the regular supply, and also fitted with covers, so that they had about ten gallons, an amount which was considered sufficient.
The matter of fuel was a more difficult one to solve, unless they intended to prepare most of the food before starting; but George insisted that the small stove should be put aboard, and about fifty pounds of the coal stowed away.
"How long do you think we should provision for?" was George's inquiry, as they were carrying the various things aboard.
Harry had no ideas on the subject, but the Professor ventured the opinion that at least two weeks' supply should be arranged for.
This conclusion rather startled the boys, who had not expected more than a few days' trip, and when they questioned him about his reasons for making the statement, he said: "Did you ever hear of the old lady who attended a special meeting of prayer for rain? She came with an umbrella, and the people laughed and chided her. The minister reproved them, saying: 'She, at least, has faith, which you have not.' We are going for two purposes: one is to learn something about the island we are on, and the other to rescue our companions if they can be found. We couldn't rescue them and let them starve."
