Mr. Isaac Collins communicates the following to the Hay-ward Journal:

"The very large yield of fuel material from twenty acres of Stratton's Eucalyptus grove in Castro Valley may be of some use to Californians in general, and from the wide dissemination of your paper that end can be attained. The grove was planted in the winter of 1869-70. The twenty acres cultivated to the above was entirely cleared of the timber in the year 1880. The quantity and value of the fuel obtained therefrom were as follows:

From time of planting to 1875 ..............

. 12 cords

During year 1876 ...................

. 149 "

And 700 telegraph poles.

1877 .........................

. 100 "

1880 ..............................

.1000 "

And cords of roots

100*

Total number of cords ..

1,361

At $6 per cord .................

$8,166

700 telegraph Poles ..................

525

150* of cords roots at $4 per cord ................

600

Grand total for 20 acres ..................

$9,491

"*1 communicated the above to the State Horticultural Society, but since that time, in speaking on the subject to one of the contractors, he amended his first statement to me to 250 cords of roots and also $200, for piling for creek embankments".

It would be well worth while to know what could be made off the same ground by other crops in the same time. These figures give $50 per acre per year; but, as the money is not handled till ten years, compound interest will have to be charged against the proceeds, and in favor of some annual crops. On the other hand, there is much labor attendant on annual crops, which a timber plantation is free from. At any rate, when we can get careful statements like these, the chance to make comparisons should not be lost, as it is just what is needed to induce people to go into timber culture, if there is really any money in it.
