On the Homestead
In the southern Cascade mountains of Oregon it's been raining for four or five days. Pounding rains, uninhibited rains, land watering rains. It's been good for the soul.
Our March weather was hot, dry and windy - with temperatures breaking unprecedented records a time or two. One day in March I read it hit the 90 degree mark somewhere down in southern California. It seemed the whole west coast was experiencing much of the same.
We sheared in March during one of those long respites when the goats could shed their heavy fleeces and bask in warm sun, and I kept waiting for the usual "bite" and fury of a cold snap to ride in and spoil it all. Ol' Sol just kept shining for us and I never did have to get out the thrift store sweaters to put on the newly shorn goats. It just didn't seem like March. April was more of the same - warm sunshine and little rain. May was more subdued, a bit tempestuous with a rainstorm or two, green as Ireland with clover grass coming on strong in our pastures.
Now that June has arrived, it's nice to pull out long forgotten sweaters and trudge through the muddy paths of the garden remembering why we wait so long to put out tomato and pepper plants, and why we don't plant beans until June 1st at the earliest.
I watched the old farmer across the street, my gentle neighbor Ike, cut his large field of grass hay. Swath after swath of long tall grass fell over until the entire huge field was cut. That all happened on our last sunny day before the rains came. So, he lost a crop of hay this year. Rained on hay is basically washed out hay, nutrients so important to livestock leached out with the rainfall.
Safe Hay Storage
Now is the time to think of gathering hay harvests though summer is not fully ripe yet. SAFE hay storage is for us a necessity, especially since we finally (after many years) have a pretty nice barn to keep our hay in these days. The hand wrought timbers in that barn hold the weight just fine. The mows are spacious, each mow holding approximately 12-15 tons.
Last year we bought a few tons of grass hay locally and I still recall the lesson my husband gave me one hot morning as we stood examining a bale of green clover hay that he had just unloaded from the white International pick up. He reached a hand right into the bulky bale and said, "seems awfully warm in here." Then he pulled out a small wad of long leafy grass. It looked so pretty, so fresh. It almost looked as though it wasn't entirely dry. That's because it wasn't!
He took that long length and grabbed one end with one hand and the other with his other hand and "twisted" it around and around. "They say eight or nine times and if it doesn't snap, it's not ready yet to be baled." The pieces of grass in his hand refused to break. It truly was too "green."
"What do we do with this batch of hay?" I asked him. He had a place to store it, outside the barn. We would stack it there and cover it with a tarp. We would not be taking any chances on a barn fire. The rest of the hay we gathered throughout the summer was carefully looked over by my careful husband and we never got another batch of "too wet" hay, thankfully.
Barn fires are never fun. Though seeming to be a blessing, a gorgeous lot of green hay stored away in a barn mow can be a disaster in the making if it is improperly cured hay that is being stored. I recall the day one farming wife whose daddy had her milking Jersey cows during the Depression Era of the 30's told me of her close call with a barn fire.
"I was milking one of those Jerseys and suddenly I look up and see smoke puffin' in great clouds from one of the hay bales."
"What did you do?" I prodded her during a lax moment in her story.
"Well, I stood up with my milk pail and doused that hay with milk!" According to her it put out the fire.
All last summer I watched the hay in our mow carefully and each time I opened a bale for the goats, I looked to see if there were any "warm spots" inside the hay that would give cause for any concern. All seemed well in that regard.
Stan was doing some research one day and found a great article that succinctly explained what signs to look for or rather "smell for" in one's hay loft. After reading it, I sent an e mail to its author, asking him for his permission to reprint the article here, and he graciously extended it stating in his reply e mail: "Please feel free to use it if you feel it can help prevent a barn fire." I include it herewith. Pin a copy to a barn wall.

SPONTANEOUS COMBUSTION AND HAY FIRES
Harold K. House, P. Eng., Dairy and Beef Structures and Equipment Specialist
Ontario Ministry of Agriculture and Food - Clinton, Ontario. (July 1998)
Lives have been lost and hay crops destroyed because of fires caused by spontaneous combustion. This year has been particularly bad for hay heating due to the hot humid weather. If the hay crop is put into the mow above 20-25% moisture content, spontaneous combustion may occur.
A hay crop that is placed too wet into a mow will heat rapidly. If the mow is so large that heat loss is restricted, the internal temperature will rise. As the temperature rises above 130 oF (55 oC), a chemical reaction occurs and may sustain itself. This reaction does not require oxygen, but the flammable gases produced are at a temperature above their ignition point. These gases will ignite when they come in contact with the air.
Check your hay regularly. If you detect a slight caramel odour or a distinct musty smell, chances are your hay is heating.
What do you do if you suspect that your hay is heating? First of all, make yourself a simple probe that can be inserted into the hay mass to check the temperature. A probe can be made from a 10 foot piece of electrical tubing. Rivet a hardwood pointed dowel to one end and drill 8 - 3/16 inch diameter holes in the tube just above the dowel. Drive the probe into the hay mass and lower a candy thermometer on a long string into the probe. The thermometer should be left for 10 minutes to ensure an accurate reading.
Watch for the following temperatures:
150 oF (65 oC) ** ENTERING THE DANGER ZONE. Check temperature daily.
160 oF (70 oC) ** DANGER! Measure temperature every four hours and inspect mow.
175 oF (80 oC) ** CALL THE FIRE DEPARTMENT! Wet hay down and remove from the barn.
185 oF (85 oC) ** HOT SPOTS AND POCKETS MAY BE EXPECTED. Flames will likely develop when heating hay comes in contact with the air.
212 oF (100 oC) CRITICAL! Temperature rise is rapid above this point. Hay will almost certainly ignite.
CAUTION: Before entering the mow, place long planks on top of the hay. Do not attempt to walk on the hay mass itself. Pockets may have already burned out under the hay surface. Always tie a rope around your waist and have a second person on the other end in a safe location to pull you out should the surface of the hay collapse into a fire pocket.
Extreme caution should be taken when fighting a hay fire if hay has been treated with chemical preservatives. Hay treated with preservatives containing ethoxyquin and BHT (butylated hydroxytoluene) will produce hydrogen cyanide gas at around 240 oF (115 oC). This gas is very deadly. Additives containing primarily propionic acid to not produce hydrogen cyanide during a fire.
Many farmers sprinkle salt on hay as it is stored, in an effort to prevent hay fires. However, tests have shown that salt has no effect on controlling spontaneous combustion. Dry ice, liquid nitrogen or carbon dioxide gas pumped into the hay will prevent combustion by eliminating the oxygen from the hay mass.
Spontaneous combustion is not an accident. By following good storage practices, not only will spontaneous combustion by avoided, but a higher quality of hay will be obtained.
Goats and More Goats
May was our "birth month" for the most part. Approximately 25 new kid goats dropped on the ground during that busy month, and though a few popped out white as the driven snow, we were awed by our share of color. One late May night the intercom signaled my light-sleeping husband that someone was in labor up there at the barn. I knew by my calendar at least three or four were soon due.
"Why do they wait until now?" I asked my husband as we both dressed in regal barn attire for the trek upward the hillside to the barn. I pulled the rabbit angora cap snugly around my head and we both ventured outside, our barn coats tight around us. The stars were twinkling in a deep black sky above us, nature's cathedral filled with light.
By the time we entered the barn, its sole electric light showed us a new kid had already been dropped. "Black as midnight," I heard my husband's soft spoken words. Indeed, she was black as midnight. Diane had given birth, lovely white Diane whose dam is a registered white goat and whose sire was a nice silver buck. "So much face hair already that she's almost snow-blind!" Stan laughed. Indeed, she had a lot of hair for a newborn kid!
So, we doctored up Diane, made sure the kid was nursing, and trudged on home, happy at 11 pm. At 1:00 am, my sweet husband turned to me and said, "sounds like another out there ready to give birth." My sleep was being interrupted again, I noted. I also took quick mental note that tonight seemed to be a strange night in that all the goats had decided it was time to "let go" of their cargo in the middle of the night.
So, we were up and dressing again as the sounds of a laboring goat kept streaming through that intercom speaker. I said, "Might be Donna's Silver giving birth. She's about due. Or might be #87. She's due." I was a bit excited about both of the gals, having bred them both to Dakota, a dark brown buck who seems to never fail to give color to his progeny.
"Midnight black," I heard my husband say as he greeted the new mother, Donna's Silver. Indeed, she was midnight black. "And another girl," I added as I took the necessary time to find out what sex the newborn was. "Two nice doelings tonight, both black. Two nice additions to Singing Falls Mohair," I smiled over at my tired husband. We took out the iodine spray bottle, sprayed the navel. "They are both suckling just fine," I said. We trudged back to the warm house.
At four in the morning was when #87 decided it was her time to give birth. Another girl. Another black girl. So, that starry starry May night held three wonderful surprises for us, intrepid goatherds that we are. Three nice surprises.
Early this month, the day before the last day of school, actually, a group of kindergartners and first graders, 11 children in all from the local school drove up our drive in their shiny yellow school bus. The six or so adults that accompanied them were just as anxious to see all the angora goats on this goat farm. We took them up to the barn first, where they got to see all the rambunctious kid goats jumping from rock to rock, all bundles of color. Their mothers, the does, stood patiently to the side watching the carnival.
"Just how many goats do you have here?" asked one of the adults, the bus driver, if I'm not mistaken. It was a decent question and one I should have expected, but it caught me off guard.
"I don't know," was my truthful answer. "I think about 70. Maybe 75." Finally I asked someone there to please count and tell me, because I certainly needed to know. They all laughed.
We stood there together in the yard watching goats and watching children fascinated by tiny goats who ran from them as they carefully pursued their bounding forms. (All of us then asked the children not to chase the goats, and they readily complied.) Whenever my husband scooped up a kid goat in his arms, the children huddled in closely so that they could "touch" all that soft baby mohair and pet the small creature. The adults, too, reached forth their hands to pet the small goats. Everyone seemed fascinated by the little bundles of mohair.
"Colored mohair?" asked one lady incredulously. That was the kind of question I had hoped to answer, and I told them all about colored angora goats, or as much as I thought they'd want to know.
Our herd is very large these days - large and colorful! I still recall the days when we had 20 or so angora goats in our herd. Life was not as rushed then. I knew every name and no goat was named by the number stamped into its ear tag alone. If one black doeling was born in an entire birthing season, we felt fulfillment. Now we have three born in one night and call it good.
Times change to be sure. It's been a very profitable spring. Summer is on the horizon. My spinning wheel and loom will be busy - with colored mohair.
